Modified Luxury Watches: What Buyers Should Know

The case, brought by a major Swiss watch brand's US company against a Texas reseller called BeckerTime, was decided by the Fifth Circuit, which covers Texas, Louisiana and Mississippi. The seller bought genuine watches, many of them older models, and resold them with aftermarket bezels, dials, diamonds and bracelets under the original brand name. The brand sued for trademark infringement and counterfeiting.

Issue	What the court held
Were the modified watches still "genuine"?	No. Adding aftermarket parts made them materially different from what the brand sells, so the refurbishment defense did not apply.
Trademark infringement	The finding of infringement was upheld.
Can sellers customize at all?	Yes. The court noted that with the right disclosures, the seller was free to customize watches for customers upon request.
Money damages	The brand did not recover the seller's profits, because it waited too long to sue and did not show malicious intent.
Injunction	Sales of watches with non-genuine bezels under the brand name should be stopped.

The court first ruled in January 2024 and issued a revised opinion in March 2024. A later order in November 2024 dealt with the exact wording of the injunction. This page summarizes public reports and opinions for buyers; it is not legal advice.

Trademark law generally lets anyone resell a genuine branded product. It also allows sellers to repair or refurbish goods and resell them under the original name, as long as the product is not changed so much that it becomes something different, and the work is disclosed. The court found that adding aftermarket diamonds and replacing bezels and dials goes past refurbishing: the result is a different product that the brand never made, sold with the brand's name on the dial.

That is the core risk for buyers. A modified watch can contain a genuine movement and case and still not be a genuine factory watch as a whole. How it is described when sold is what the law cares about.

• Switzerland: the Swiss Federal Supreme Court drew a line between personalizing a watch for a specific client, which it treated as acceptable, and offering modified watches to the public under the brand, which it did not.
• France: a French court ordered a jewelry company to stop selling modified watches of a major brand.

The common thread across courts is the same as in the US decision: customization for a client who asks for it, clearly disclosed, is treated differently from marketing modified watches as if they were the brand's own products.

Based on the court's reasoning, a careful listing for a modified watch makes clear:

1. That the watch has been modified after leaving the factory.
2. Which parts are aftermarket: bezel, dial, bracelet, case set with stones.
3. Who did the work, if known, and that the maker did not.
4. That the maker does not endorse the modification or the seller.
5. The diamond details: type, approximate total carat weight and grade.
6. Whether the original parts are included.

If a seller avoids putting these points in writing, treat that as information about the seller.

• Owning an iced watch is not illegal. The case was about how modified watches were marketed and sold.
• Disclosure protects you. A written record of modifications helps with insurance, service and resale.
• Expect the factory warranty to be gone. See does adding diamonds void a watch warranty.
• Expect resale to follow the base watch. See aftermarket diamond watch resale value.
• Authenticate the base watch. Modification can hide non-genuine parts. See how to spot a fake luxury watch.

Our watch pages keep maker names out of page titles and headings, and every listing describes the watch by maker, model, case size, dial, metal and price. Where a watch carries diamonds, the listing says where they sit and, when available, their grade. Maker and model names in a listing identify the watch; they do not mean the maker made, approved or sponsors any modification or Franky Diamonds. Before buying any diamond watch, ask who set the stones and get the answer on your receipt.

4. Ask whether original parts come with it.
5. Get every point on the receipt.
6. Keep the receipt with your insurance documents.

• Trademark infringement: using a brand's name or logo in a way likely to confuse buyers about what they are getting or who made it.
• Refurbishment defense: the rule that lets sellers repair and resell genuine goods under the original name, as long as the product is not materially changed and the work is disclosed.
• Materially different: changed enough that buyers would care, such as different parts or added stones.
• Injunction: a court order to stop doing something.
• Disgorgement: making a defendant give up profits.
• Laches: a defense that the plaintiff waited too long to sue.

Date	What happened
August 2022	The federal district court in Texas entered judgment, finding infringement
January 2024	The Fifth Circuit affirmed the infringement finding and sent part of the injunction back
March 2024	The court issued a revised opinion
November 2024	A further order addressed the wording of the injunction

• It did not make it illegal to own a watch with aftermarket diamonds.
• It did not target buyers; it was about how a seller marketed and sold modified watches.
• It did not ban customization. The court said customizing for customers who ask, with the right disclosures, is allowed.
• It is binding in the Fifth Circuit (Texas, Louisiana, Mississippi). Courts elsewhere, including Florida's, may look to it but are not bound by it.

Nothing about the case changes what you can do with a watch you own. Keep the paperwork that shows what was done to it, keep original parts if you have them, and describe it honestly if you sell it: modified, which parts, which stones. That protects you and the buyer, and it is the standard a careful dealer will expect.

The court case was between a brand and a seller, but the lesson lands on buyers. A modified watch sold without disclosure can surprise you three times: when the maker will not service it, when a dealer offers far less than you expected, and when an insurer asks what exactly was on your wrist. A written description of every modification solves all three. It costs a seller nothing to write down the truth, so a seller who will not is telling you something about the watch.

Jewelry buyers already have disclosure rules on their side. The FTC Jewelry Guides require sellers to disclose that a diamond is lab-grown, that gold is plated rather than solid, and to mark karat honestly. Those rules exist for the same reason as the watch case: what a piece is made of, and what has been done to it, changes what it is worth. A modified watch deserves the same plain description as a plated chain or a lab-grown diamond ring. Use the same habit for both: ask what it is, ask what was changed, and get it in writing.
