What Is PVD Coating on Jewelry and Watches — and How Long Does the Finish Last?

If you buy watches and jewelry for a living, you have seen this sequence before. A sample arrives with a warm, even gold tone. You photograph it, list it, and it sells. Six months later a customer sends you a picture of the same piece with the tone rubbed away along the clasp, the inside of a ring band, or the edge of a watch case. That single photo can undo a season of work, and it always leads to the same question: how long is a finish supposed to last, and who is responsible when it does not?

That question is why more wholesale buyers are now asking about PVD coating on jewelry and watches before they talk about price. PVD is a vacuum-based surface treatment that produces a hard, colour-stable finish on stainless steel and other metals. It is not a marketing invention; the same family of processes is used on cutting tools, aerospace parts and medical instruments, where a surface failure is far more expensive than a returned necklace.

This article is written from the manufacturing side of the table. Aurevo is a Shenzhen-based manufacturer of watches and jewelry producing for wholesale, OEM, ODM and private label programs in more than 65 markets, and the questions below are the ones our sales engineers answer every week. We will explain what PVD coating actually is, why "how long does PVD coating last" has no honest single answer, which variables really decide durability, and - most useful of all for a buyer - how to write a surface-finish requirement into a purchase order so that the obligation is clear, the inspection is objective, and your claim is enforceable. Every product we ship carries a 12-month warranty covering manufacturing defects in normal use, and there is a dedicated section below on how that warranty interacts with a coated surface.

What Is PVD Coating on Jewelry and Watches?

PVD stands for physical vapor deposition. In simple terms, a solid coating material is turned into vapour inside a vacuum chamber, travels across the chamber as a plasma of atoms and ions, and condenses onto the surface of the part you are coating, where it builds up into an extremely thin, dense film.

The important word is physical. Electroplating, the older and much more common method of putting a gold colour on base metal, works by passing current through a chemical bath so that metal ions deposit onto the part. PVD does not use a plating bath at all. There is no liquid chemistry touching the part, no drag-out, no rinse water, and no wet chemistry waste stream to manage. The coating material is delivered as a vapour in a vacuum and bonded to the surface.

That difference in how the film is formed is the reason the two processes behave so differently in the field. A plated layer sits on the surface, bonded mechanically and electrochemically. A PVD film is bonded at the atomic scale to the substrate, and it can be significantly harder than the metal underneath it. The practical consequences for a buyer are greater resistance to abrasion in the places that get touched, and better colour stability over the life of the piece.

The coating materials you actually buy

When a supplier talks about PVD, they are usually talking about one of a small family of coatings. Each has its own colour and properties, and the colour is a function of the coating chemistry rather than a dye or a pigment.

• Titanium nitride (TiN) - the classic PVD gold tone. A hard, wear-resistant film with a warm yellow-gold appearance.
• Zirconium nitride (ZrN) - a slightly softer, more champagne or greenish-gold tone that many buyers prefer for women's collections because it reads closer to a light gold alloy than to brass.
• Chromium nitride (CrN) - a cool silver-grey, widely used on steel watch cases and bracelets that should keep a steel look with improved surface hardness.
• Titanium carbonitride (TiCN) and diamond-like carbon (DLC) - darker gunmetal to near-black finishes common on sport and men's models.

None of these is a paint or a lacquer. You cannot buy a "PVD colour" the way you buy a Pantone swatch; you buy a coating chemistry plus a surface preparation plus a thickness specification, and the visible result is the outcome of all three. That is also why two suppliers can both offer "gold PVD" and deliver visibly different tones.

Where PVD sits in a watch or jewelry production line

A coated surface is one of the last things that happens to a part, and everything that happened before it matters. In watch and jewelry manufacturing the sequence typically runs: forming or casting, machining or filing, polishing or brushing to the desired base finish, cleaning and degreasing, then the coating step - PVD, plating, or a lacquer - followed by final assembly, setting stones or joining components where relevant, and inspection.

Two consequences follow from that order, and both affect your order:

• Surface preparation is not optional. A mirror-polished part and a coarsely brushed part do not produce the same coated result. Residual polishing compound, oil or fingerprints on the surface will show up as adhesion failure or as a visible defect, not as a small cosmetic nuisance.
• PVD is a line-of-sight process. Because the coating material travels through the chamber as a vapour, recessed areas and deep internal surfaces are harder to coat evenly than outward-facing surfaces. Complex geometries need masking plans and, sometimes, fixturing so that the visible faces are oriented toward the vapour source.

What PVD is not

It is worth clearing up three misconceptions that regularly appear in buyer enquiries.

First, PVD is not a solid gold layer. It does not contain enough precious metal to have a measurable resale or scrap value, and it should never be presented to consumers as gold. It is a hard, decorative surface treatment.

Second, PVD is not a coating you can apply as an afterthought to a finished watch that is already assembled and sealed. In practice the parts that will be coated are handled as separate components, and any stone-set or glued assembly has to be considered in the masking plan.

Third, PVD does not make a piece indestructible. It changes how the surface behaves under abrasion and chemical exposure. It does not protect a watch against water ingress, and it does not change the engineering of a clasp, a crown or a caseback gasket. Those are separate specifications with their own tests and their own warranty considerations.

Why the Question Comes Up in Wholesale and Private Label Ordering

For a retailer or a brand owner, a surface finish is not an aesthetic detail - it is a return-rate variable. When a finish fails early, the cost is never limited to the price of the piece. You absorb the refund, the shipping, the marketplace penalty, the review, and the value of the customer relationship. In a wholesale channel the same failure is worse, because your business customers see it across dozens or hundreds of units at once.

That is why experienced buyers treat the finish as a specification to be written down, quoted, sampled and inspected rather than a phrase in a catalogue. Three questions do most of the work:

• What exactly is the surface, in chemically and visually describable terms?
• What conditions is it expected to survive, in the customer's real usage?
• If it fails inside the warranty period, what evidence decides whether it is a defect or normal wear?

If your supplier cannot answer all three in writing, you do not yet have a specification. You have a promise. The rest of this article is about turning that promise into language a factory can build to and a buyer can verify.

How Long Does a PVD Coating Last?

Here is the honest answer, and it is the reason this section is the longest in the article: there is no single number, and any supplier who gives you one without conditions is guessing.

Search for the lifespan of a PVD finish and you will find confident statements ranging from a couple of years to "a lifetime". Almost all of them are written by someone selling coatings, and almost none of them define the substrate, the surface preparation, the coating chemistry, the coating thickness, the contact points, or what "still good" means. Two identical-looking watches in the same shipment can come back with completely different wear patterns, because the wear happened in different places.

What a competent manufacturer can do is different and more useful: define the variables, agree which of them are fixed by the order specification, state which quality checks will be performed, and commit to a warranty position for defects inside a defined period. Aurevo publishes a 12-month warranty on all watches and jewelry covering manufacturing defects in normal use, and we confirm the finish specification for each order in the proforma invoice against an approved sample. What we do not do is publish a micron figure or a wear-test number we have not verified on your specification, because that number would be meaningless the moment your design changed.

The variables that actually decide how a finish ages

If you want to predict how a coated surface will hold up in a specific market, look at these in order. Each one can move the outcome further than any marketing claim.

• The substrate. A dense, corrosion-resistant base such as 316L stainless steel gives a coating a stable foundation. A soft base metal that dents easily will damage the coating from underneath, because the film is thin and cannot bridge a dent.
• Surface preparation before coating. Polishing quality, cleanliness and degreasing decide whether the film bonds. This is the single most common root cause of a finish that "peels" instead of wearing.
• Coating chemistry. TiN, ZrN, CrN or DLC behave differently in abrasion and chemical exposure, and the correct choice depends on the piece and the market rather than on fashion.
• Coating thickness, within the agreed specification. Thin films are cheaper and look correct on day one; thicker films take longer in the chamber and cost more. This is a commercial choice you make explicitly, not a detail to leave to the factory.
• Contact points and geometry. The clasp, the link edges, the ring band's inner face and the watch case's corners take the load. A design that concentrates friction in one small area will always show wear earlier than a design that spreads it.
• Chemical exposure. Chlorinated pool water, perfume sprayed directly onto metal, sunscreen, hair products and hand sanitiser all attack finishes. Two customers can buy the same ring and get different results purely from lifestyle.
• Cleaning habits. An abrasive metal polish used on a coated surface will remove or dull the film. Soft cloths, mild soap and water are appropriate; polishing compounds are not.

Colour stability and coating integrity are two different questions

Buyers often merge these, and the merge hides the real risk. Colour change - a gold tone drifting toward a duller, greyer or slightly patchy appearance - is a cosmetic outcome, and it is usually gradual. Coating integrity - the film lifting, blistering or flaking away from the substrate - is a bonding failure, and it usually shows up early and in patches rather than as overall fading.

The distinction matters because the two have different causes and different responses. Gradual tone change is a wear story, and it is managed through realistic expectations, care guidance and a specification that matches the price point. Bonding failure inside the warranty period is a manufacturing-defect story, and it should be documented, investigated and remedied by the supplier. When you write your purchase order, define both: the tone you approved against a physical sample, and the adhesion behaviour you expect.

What to commit to in the order instead of a lifespan claim

A useful finish specification replaces the vague question "how long will it last?" with commitments that can be built to and inspected against. In practice, for a coated watch or jewelry order, the written specification should fix the following. It should name the substrate by material, not by family. It should name the coating system and the visible tone, referenced to a physical approved sample rather than to a photograph or a screen. It should state which surfaces are coated and which are masked. It should state the base finish (mirror polish, satin, brushed, matte) because the same coating over different base finishes gives a different appearance. It should state the inspection method and the acceptance approach you will use, and whether a buyer-nominated third party will verify it. Finally, it should state the warranty period that applies to the finished piece.

PVD Compared with Other Ways to Finish a Watch or Jewelry Piece

Buyers who ask about PVD coating on stainless steel or on jewelry are usually weighing it against one or two other options. The comparison is commercial as much as technical, and it is worth making surface by surface rather than for the product as a whole.

Electroplating deposits metal from a chemical bath using electrical current. It is the most widely used method for putting a gold colour on base metal, it covers a wide range of tones, and it is the lowest-cost route at volume. Its limitations are the ones buyers already know: the layer is comparatively soft, it fades at the points that get touched most, and wet-chemistry control in the supply chain has to be managed carefully. For fashion jewelry at an entry price point, or for pieces that are not expected to survive heavy daily wear, plating can be a perfectly rational choice.

PVD deposits the coating material from a vapour in a vacuum, and the resulting film is bonded at the atomic level. It is harder, more abrasion-resistant and more colour-stable than a plated layer, and it uses no plating bath chemistry. It costs more per piece, because it needs vacuum equipment, careful preparation and often masking, and it is the sensible choice when the finish is part of what the customer is paying for.

Anodising is chemically different again: instead of depositing a new layer, it grows an oxide layer out of the metal itself. The colour is therefore integrated into the surface rather than sitting on it. It applies only to certain metals, aluminium and titanium being the usual ones, and its colour range is narrower than plating or PVD - which is why it is rarely the answer when a buyer needs to hit a specific gold tone.

Lacquer, enamel and e-coat are organic films rather than metal coatings. They are inexpensive, they can match an exact brand colour, and they can be applied to awkward shapes. They are also the least abrasion-resistant option on this list and can chip away from an edge. Their best use is often in places the customer does not handle, such as the interior of a caseback, rather than on the surfaces that take the wear.

Solid gold and gold alloy parts are not coated at all. The metal is the finish, so there is no layer to wear through - but the part scratches, dents and is priced at metal value, which is a completely different commercial conversation. Whether a solid metal part or a coated one is right for your line is a sourcing decision about the product, not a finish decision; our separate guide to gold plated jewelry and what it is worth deals with that question on its own terms.

Method	How the finish is created	Behaviour in wear	Main buyer consideration
Electroplating	Metal deposited from a chemical bath by current	Softer layer; fades first at friction points	Lowest cost; fit it to the price point and the expected usage
PVD	Vapour deposited in vacuum, bonded to the substrate	Harder, more abrasion-resistant, more colour-stable	Higher per-piece cost and masking planning; specify per surface
Anodising	Oxide layer grown from the metal itself	Integrated with the surface; does not flake like a film	Limited colours and limited metals; not a precise gold tone
Lacquer / enamel / e-coat	Organic film applied over the surface	Least abrasion-resistant; can chip from an edge	Cheap and colour-flexible; best kept off contact surfaces
Solid gold / alloy	The part is the metal; no coating layer	No layer to wear through; scratches and dents instead	Priced at metal value; a product decision, not a finish decision

In practice, experienced buyers often specify more than one process within a single collection. A caseback interior that nobody sees can take an inexpensive coating, while the bezel, bracelet and clasp - the surfaces the customer actually touches - get the better process. The discipline that makes this work is simply to decide it per surface, write it down per surface, and confirm that each process suits the substrate it is applied to.

How the 12-Month Warranty Meets a Coated Surface

Every Aurevo watch and jewelry product carries a 12-month warranty that covers manufacturing defects appearing in normal use. This is a uniform position across our range rather than a variable to be negotiated per order, because a warranty that changes with every shipment is not a warranty a buyer can plan around.

For a coated surface, the warranty is only meaningful if both sides understand where the line falls between a defect and wear. In our experience that line is usually clear, and it becomes clearer when the claim arrives with good evidence.

What a manufacturing defect looks like on a coated part

Defects that we treat as covered include coating that lifts, blisters, flakes or peels in normal use; visible patchiness or colour gaps that indicate an incomplete or inconsistent coating rather than gradual wear; coated surfaces that were masked or uncoated where the approved specification required coverage; and finish failures traceable to a contaminant or a process deviation that we can identify in the production record.

What normal wear is not

Wear is not a defect. Scratches from contact with keys and abrasive surfaces, tone change at heavy friction points over months of daily wear, dulling from abrasive polishing compounds, and damage from chemicals such as chlorine or concentrated fragrance are all normal-use outcomes. They are worth planning for through the specification and through consumer care guidance, but they are not covered by a manufacturing warranty, and a supplier who tells you otherwise is simply going to refuse the claim later.

How a finish claim gets resolved

Quality issues are documented on receipt. We ask buyers to raise claims within 30 days of receiving a shipment, with photographs and the affected batch numbers, so the pieces can be traced back to the production run and the process record can be checked. Verified defects are remedied through replacement in a following order, a discount against the affected value, or a refund of the affected value, depending on what is practical for the buyer. Spare parts such as straps, buckles, clasps and batteries can be included with orders to support after-sales service in your market, which is often faster and cheaper than returning a complete unit. The general expectations to set with any supplier are set out in our article on what warranty you should expect when buying wholesale.

PVD and the Metals You Buy: Stainless Steel, Titanium and Plated Substrates

The substrate is the part of the discussion buyers skip most often, and it is the one that decides how well a finish ages. Three substrate situations cover most wholesale orders.

Stainless steel is the workhorse of coated watches and jewelry, and 316L stainless steel is the grade most commonly specified for watch cases, bracelets and jewelry that need corrosion resistance in humid conditions and against skin contact. The alloy itself is chosen for properties independent of the coating, which is why we treat the grade decision and the finish decision as two separate questions in the specification; if you want the material reasoning rather than the finish reasoning, our article on what grade of stainless steel to look for covers it in detail.

Titanium is used where lightness and skin compatibility matter. It takes PVD well, and titanium substrates are common in higher-end watch cases and in jewelry aimed at sensitive-skin markets. Where lightness is the sales argument rather than the finish, the substrate choice comes first and the coating follows.

Coated base metals are the trickiest case, and they are common in fashion jewelry. A brass or alloy part that has already been electroplated and is then coated has two layers whose behaviour has to be considered together. If the plating under the PVD is inconsistent, the visible finish will fail from underneath. When a buyer asks us to match a competitor's gold tone on this kind of construction, the first thing we need to establish is what the base part actually is, because a tone that is achievable on 316L stainless steel is not automatically achievable on a zinc alloy casting.

One more point belongs here because buyers ask about it directly: whether a coated piece is suitable for sensitive skin depends on the material that ends up in contact with the skin, and on how the piece is constructed, not on the fact that it carries a coating. We cover the sourcing side of that question in our guide to nickel-free and hypoallergenic sourcing; for a coated order, the practical action is to declare the base material in the specification and to confirm any specific compliance document your market requires at enquiry.

How to Write a PVD Finish Specification Buyers Can Enforce

This section is the operational core of the article. Everything above explains why the variables matter; below is how to capture them in the language of an order.

1. Name the substrate by material

Write "316L stainless steel" rather than "stainless steel", and write "brass" rather than "alloy" if the part is brass. If the piece is plated before coating, say so, and identify which layer is visible where. Vague substrate language is the reason so many finish disputes end with both sides believing they are right.

2. Fix the tone against a physical sample

Colour approved from a phone photograph is not a specification. Screens render warm metals differently, and lighting in your office is not lighting in your customer's bathroom. A tone is approved against a physical master sample - a golden sample held by the factory and, where possible, a counter-sample held by you - and it is compared under consistent lighting at an agreed distance. When you ask for a champagne-gold tone, be precise about what you mean by it: to some buyers champagne gold means a very pale, slightly warm silver-gold, and to others it means the deeper yellow of a yellow-gold alloy.

3. Define the base finish and the sheen

Mirror polish, satin, brushed and matte are different visual products and different processes. Specify the sheen on each visible surface, because on a watch it is normal for the bezel to be polished while the bracelet links are satin-brushed, and that mixed finish has to be described surface by surface rather than as one instruction.

4. State coated areas and masked areas

Say which surfaces are coated and which must not be: casebacks where a reference is etched, threads, spring-bar holes, snap-fit joints, stone settings and any surface that will be soldered or glued later. Masking instructions prevent a whole class of rework, and they tell the factory how to fixture the parts in the chamber.

5. Describe the parts as components

Specify whether the pieces will be coated as loose components or as assembled units. Loose-component coating gives better coverage and is normal for watch cases and bracelets; assembled pieces with stones already set usually cannot be coated without damaging the setting. Getting this wrong in the quotation stage is an expensive mistake, because it changes the process route rather than the price line.

6. Set the inspection approach, not a magic number

Instead of demanding an unverified figure, define how the finish will be judged: visual inspection of the full visible surface under an agreed light level, comparison against the master sample, examination of edges and contact points, and confirmation that masked areas were respected. If your market or your customer requires laboratory verification, nominate the third-party laboratory and the method, and agree who pays; we support third-party inspection such as SGS, BV or TUV at the buyer's cost, and we will confirm at enquiry which methods we can support on a given specification. Where a test method is not already part of your standard, the correct pattern is: the buyer defines the requirement, the supplier confirms whether it can be met, and both write it into the proforma invoice before production starts.

7. State the warranty period on the finished piece

Write the period into the order and let it apply uniformly across the shipment. Our position is 12 months covering manufacturing defects in normal use, and we would rather decline an order we cannot warrant than sell a finish and then argue about it.

An example of a finish clause

The following block is the shape of language that removes most finish disputes. Replace the bracketed sections with your own values, and confirm every one of them with the factory before the proforma invoice is issued.

Part	Ladies three-hand watch, 32 mm, case and bracelet as per drawing
Substrate	316L stainless steel, case and bracelet
Coating system	PVD [chemistry], tone approved against master sample [reference]; coating thickness specification confirmed at enquiry
Base finish	Bezel mirror polish; bracelet links satin; caseback satin
Coated / masked	Coat all visible external surfaces; mask caseback engraving area, threads, spring-bar holes, crown tube seat
Coated as	Loose components; assembly after coating
Inspection	100% visual against master sample; final inspection per agreed level; buyer-nominated third-party inspection accepted at buyer's cost
Warranty	12 months, manufacturing defects in normal use
Sampling	Finish sample approved before mass production; sample lead time confirmed at enquiry

How to Inspect a PVD Finish at Sample and Bulk Stage

A finish specification is only as good as the inspection that follows it. In our own production, more than 40 quality-control stations run across the process, from incoming material inspection to final inspection, and a coated watch or jewelry order is checked at more than one of them because the coating step can introduce defects that the pre-coating inspection could not see.

For buyers, the practical inspection routine at sample stage is short and cheap, and it prevents most bulk-stage surprises:

• Inspect under more than one light. A warm store light flatters a gold tone. Look at the sample under cool white light and under daylight, and compare against your master sample rather than against memory.
• Look at the contact points first. The clasp, the link edges, the case corners and the inside of a ring band tell you more about a finish than the display face does.
• Check the masked areas. Confirm that the surfaces you asked to leave uncoated are actually uncoated, and that no overspray, shadowing or residue sits next to them.
• Confirm mixed finishes. If the design calls for polished bezel and satin links, check that the sheen boundaries are where the drawing says they are, and that they are clean rather than blended.
• Handle it for a day. Put the sample through normal handling - put it on, use the clasp, wipe it - before you approve it. Very small wear marks appearing within a day of gentle handling are worth discussing before you commit to thousands of units.
• Record what you approved. Keep photographs, the sample reference, the inspection date and the light conditions with the approved sample, because that record is what makes a later claim objective.

At bulk stage, the routine shifts from judgement to consistency: verify that the production pieces match the approved sample, that the colour is consistent across the whole shipment rather than only within a box, and that the packing protects the surfaces in transit. Our articles on what quality checks to expect from a manufacturer and on how to evaluate a sample before placing a bulk order go deeper on both routines.

What Drives the Cost of PVD Coating on Jewelry and Watches

Buyers often ask how much PVD coating costs, and the honest answer is that no responsible supplier quotes a coating price without seeing the piece. Coating is priced against a process route, and the route changes with the design. The variables that move cost most are these:

• Part size and chamber loading. A coating chamber holds a finite load. Large cases consume more of that load per piece than small findings, and small components with awkward geometries consume more than flat ones.
• Masking complexity. Every surface that must be protected needs masking, and masking is hand work. A design with many masked features costs more to coat than a simple outward-facing surface.
• Base finish preparation. A mirror polish before coating takes more labour than a satin finish, and the polish quality affects the coating result.
• Coating chemistry and thickness specification. Different chemistries and thicker films take longer in the chamber or require additional process steps.
• Reject and rework rate. Coating is a late-stage operation, so a rejected part carries all the value already added to it. Suppliers who quote unrealistically low coating prices are usually planning to pass that risk back to you.
• Order quantity. Coating has set-up time, so the per-piece cost falls as the quantity rises. This interacts directly with your minimum order quantity: standard watches typically start from 100 pieces, custom watches from 300 pieces and custom jewelry from 200 pieces.

A related question we see from time to time is the cost of a PVD coating machine. That is a question about buying production equipment, not about buying finished goods, and it is not a cost that belongs in a wholesale quotation. If you are exploring in-house coating, the honest starting point is a different conversation about facility requirements, chamber capacity, process control and the skills to run it - and it is worth being clear that buying a chamber is the easiest part of that project. For a brand or retailer, buying the finish as part of a manufactured product is almost always the lower-risk route.

Nine Specification Mistakes That Cost Buyers Money

These are the errors we see most often when a buyer specifies a coated finish. Each one has a cheap fix at quotation stage and an expensive fix after the shipment arrives.

1. Approving colour from a photograph. Screens and lighting lie. Approve a physical sample under defined light.
2. Using a colour name as a specification. "Champagne gold" means different things to different people. Anchor the tone to a sample and describe it.
3. Leaving the substrate unstated. The same requested tone is achievable on one base metal and not on another; the substrate decides a large part of the answer.
4. Forgetting to specify masked areas. Uncoated requirements are as important as coated ones, especially around engraving, threads and joints.
5. Asking for a lifespan guarantee in years. No supplier can guarantee how a customer will wear a piece. Ask for a specification, an inspection approach and a warranty period instead.
6. Demanding a test method the factory cannot perform. Agree the method before the order, and agree who pays for third-party verification.
7. Assuming the coating covers an assembled piece. Stone-set and glued assemblies usually have to be handled as components, which changes the process route and the price.
8. Skipping the master sample. Without a signed-off reference sample, neither side can prove what was approved, and every later conversation becomes a matter of opinion.
9. Ignoring consumer care guidance. Even a well-specified finish degrades faster under abrasive polish, chlorine and concentrated fragrance. A short care card in the box protects your returns rate, and our guide to cleaning and caring for a stainless steel watch is a reasonable basis for one.

Planning a Coated Private Label Order

If the finish is part of a private label program rather than a stock item, a few planning decisions belong early in the timeline, because they change the part rather than the paperwork.

Settle the finish before sampling. The coating system, the base finish and the masking plan all affect the component, and a sample made without them cannot be used to approve production. Changing the tone after a sample has been signed off usually means making a second sample, which costs more time than it costs money.

Decide the order of operations for your branding. If your logo or any marking will be engraved, etched or added as part of the manufacturing process, decide it before the finish step and put it on the drawing, because the sequence affects what the finished surface looks like and how the masked areas are planned.

Decide what the customer will touch. On a watch, that is normally the case sides, the bezel, the crown, the bracelet and the clasp; on a ring, it is the outer band and the inner face. Naming those surfaces in the specification is what allows a supplier to put the better process where it is felt, and a simpler one where it is not.

Plan after-sales before you order. Spare straps, buckles, clasps and batteries can travel with the shipment, which lets your market handle a worn part without shipping a whole unit back. It is a small line on a proforma invoice and a large saving on a customer complaint.

Check the commercial floor. Standard watches typically start from 100 pieces, custom watches from 300 pieces and custom jewelry from 200 pieces. The finish specification itself does not change those numbers, but heavier customisation does, so it is worth confirming the quantity band for your design while the finish is still being decided. Our explanation of how minimum order quantity works shows how MOQ interacts with customisation levels.

Frequently Asked Questions

Is PVD coating better than gold plating?

They are different processes for different price points and different wear expectations, not competing claims on the same piece. Electroplating is a mature, cost-efficient way to achieve a range of tones and is widely used on fashion jewelry; PVD produces a harder, more abrasion-resistant and more colour-stable surface, and it costs more because it requires vacuum equipment and more careful preparation. The right question is not which is "better" but which one your price point, your customer's usage and your return-rate tolerance can support. What matters in either case is that the process is named, the tone is approved against a sample, and the warranty position is written down.

Does PVD coating come off?

Any coating on any surface is subject to wear, so "never" is not a claim a serious supplier makes. What PVD resists well is the gradual fading that thin plating shows at friction points. What you should watch for instead is the bonding failure pattern described earlier - lifting, blistering or patchy flaking that appears early. That pattern points to preparation or process problems rather than wear, and inside the warranty period it is a claim we would investigate against the production record. Our 12-month warranty covers manufacturing defects in normal use.

Can a worn PVD finish be re-coated or repaired?

Not in the field, and usually not economically at the component level. Re-coating means stripping and re-running the coating process under the same controlled conditions, which is a factory operation. For a retail situation, replacement of the component or the piece is normally the practical answer, which is one reason we include spare parts such as straps, clasps and buckles with orders when buyers want to support after-sales service locally.

What thickness should I specify?

That depends on the part, the coating chemistry and how much abrasion it will see, and it is one of the parameters we confirm at enquiry against your specification rather than publish as a general figure. The reason is straightforward: a thickness that is right for a pendant that sits under a shirt may be entirely wrong for a bracelet clasp that opens and closes several times a day, and quoting one universal number would be misleading. Tell us the piece, the wear conditions you expect and your market, and we will confirm the process route that fits.

Will PVD coating work on titanium?

Yes. Titanium takes PVD coatings well, and titanium substrates appear in watch cases and in jewelry made for lightweight, skin-conscious positioning. If you are specifying a titanium piece, note that the base finish of the titanium has a visible effect on the final tone, exactly as it does on steel.

Can you match a finish I have seen from another supplier?

Often yes, and the fastest route is a physical sample rather than a description. Send the piece, or the clearest possible photograph together with information about the base material, and we will tell you honestly whether the tone is achievable on your construction. If the original is a plated zinc alloy and you are moving to 316L stainless steel, the same visual target will usually require a different coating system, because the substrate changes the way light behaves on the surface.

Is PVD safe for sensitive skin?

The finish itself is not the usual concern; the material in contact with the skin is. If your market includes customers with sensitive skin, declare the base material, state which surfaces touch the skin, and tell us which compliance documents your market requires so that we can confirm at enquiry what we can provide for that specific order and market.

Does PVD coating affect water resistance?

No. Water resistance is a mechanical property of the case, crown, caseback and gaskets, and it is specified and tested independently of the surface finish. If water resistance matters for your collection, that is a separate specification - our guide to watch water resistance ratings explains how the ratings work and what to confirm with a supplier.

Placing a PVD-Finished Wholesale Order with a Manufacturer

Once the finish specification is settled, the ordering side is a known process, and knowing the sequence in advance helps you plan a launch rather than wait for one. At Aurevo the flow runs from enquiry to a quotation valid for 30 days, then sample confirmation, then a proforma invoice and deposit, then mass production, then final inspection, then balance payment and shipment. Deposits are normally 30% by T/T with the balance before shipment, and an L/C at sight is accepted for orders above USD 50,000. Incoterms are agreed per order, most commonly EXW, FOB Shenzhen, CIF or DAP, and buyer-nominated forwarders are welcome.

Sampling is normally 7 to 15 working days, and mass production is normally 20 to 40 working days depending on quantity and the level of customisation - a range worth confirming early if your collection has a fixed launch date, because our article on production lead times explains what moves a project to the long end of that band. Standard export packaging is an individual poly bag or bubble wrap with an inner box and a master carton, and custom gift boxes, logo printing, instruction cards and barcodes can be arranged to your requirements; shipping marks are confirmed before dispatch.

You can see the kind of construction these specifications apply to in our own range: a gold-tone ladies quartz watch illustrates a polished gold-tone case and bracelet with a clean dial, the steel quartz watch shows a 316L stainless steel case and bracelet kept in a steel finish, and the gold-tone hoop earrings illustrate a champagne-gold finish on a jewelry line where consistency across the batch is the whole point. Whichever direction your collection takes, the finish conversation is the same conversation: name the substrate, approve a sample, define the masked areas, agree the inspection, and write the warranty period down.

What We Confirm in Writing, and What We Confirm at Enquiry

Buyers deserve to know which answers are fixed and which depend on the order, and we would rather say so than fill a page with numbers that would not survive your first design change. Fixed across our range: a 12-month warranty covering manufacturing defects in normal use, a 30-day claim window from receipt with photographs and batch numbers, and a documented inspection routine across more than 40 QC stations in our Shenzhen facility, where watches and jewelry are produced across multiple assembly and finishing lines. Confirmed at enquiry and then written into your proforma invoice: the coating system and tone for your part, the substrate declaration, the coated and masked areas, the base finish, the thickness specification that fits your wear conditions, the test methods we can support, and the sampling and production dates for your order.

That division is not a hedge. It is the difference between a specification you can hold a supplier to and a brochure you cannot. If you are sourcing coated watches or jewelry and want a finish specification reviewed before you commit to a run, send your drawing, your target tone and your market to our sales engineers at [email protected] or call +86 151 6001 1307, and we will tell you what is achievable on your construction, what we would need to confirm at enquiry, and where the risks in your specification sit.
