Questions and Answers

The Watch Certificate™

What is the Watch Certificate?

The Watch Certificate™ is the passport of the watch: a document signed by an expert recognized at the European level and forgery-proof. It takes the form of a steel card issued at the time of a watch purchase. This card gives access at any time to a detailed certificate with 45 control points and high definition photos taken in a watchmaking workshop. The whole thing is signed by an expert who works for auction houses.

Is the card metal?

It's made of brushed steel, it weighs 28 grams. It guarantees instant access to the certificate at a protected address. Our choice was to make it in the same material as the majority of watch cases for a simple reason: it must be durable since, in case of sale of your watch, you will give this card to the new owner. In case of loss, the data is saved and we are able to reissue your card.

What's the certificate?

Why trust these experts?

Like watchmakers, they are independent of the Watch Certificate and commit their name to each certificate. They are veritable encyclopaedias of watchmaking know-how. These experts are few in number and work mainly for prestigious auction houses.


Why create the Watch Certificate?

For 2 reasons: to find a solution against fraud, and to facilitate the purchase of a second hand watch.
When we launched Tradeewatches, our platform for the sale of second-hand luxury watches, we quickly understood the value of information in this market. We therefore wanted to offer a standard that brings transparency and peace of mind during transactions.

Buying a second hand watch is risky?

Counterfeiting has become commonplace. Our statistics for last October (2019), for example, were clear-cut, with about 1 in 3 of the advertisements posted by individuals turning out to be counterfeit. This is a very real and topical problem.

What technological innovation is behind the certificate?

The Watch Certificate is a technology that enables data to be traced from the inspection of the watch in the watchmaking workshop, through validation by the expert, to its registration in the blockchain. In a word, traceability.

What will the blockchain bring?

Forgery-proof data. The blockchain is a non-centralized database: information is recorded at different levels in an indelible way. It is therefore impossible to modify the data. It is a recognized technology in various fields, in particular that of crypto-currencies, we use it as a highly secure database.

How does blockchain anchoring work?

With each anchor, the owner receives a proof of registration in PDF format. The hash identifier is located both in the blockchain and in our centralized database.
We currently only use the blockchain as a proof of integrity and time-stamp of a trusted third party.
However, we are working on an NFT evolution that will allow you to retrieve and store your digital asset in your crypto asset management portfolio.

Here is an example of the proof of registration on the blockchain:


How are you going to remedy the counterfeiting?

First, we register and secure the serial number in a tamper-proof database. We check at least 45 control points on each watch, including the movement, the watch is opened and photographed. Finally, after the professional's analysis, an independent expert pronounces and finalizes the certificate.

How can you be sure that the certificate will never be forged?

The metal card represents only the physical entity, the certificate is on a forgery-proof database. In concrete terms, if the card were copied, the certificate (data) would remain forgery-proof.

Can a watchmaker validate a fake watch?

No, because its analysis is systematically verified by an independent expert. It is therefore not possible for a watchmaker alone to validate a certificate.

The blockchain already exists, what's the innovation brought by your company?

Adapt it to the watches. This technology is only part of the solution, our job is to organize the feedback of information, to standardize it, to pilot the network of stakeholders. Finally, we materialize this impalpable technology with a physical card, easy to use and that the wearer can transmit.

Other documents of authenticity

Is an excerpt from the brand's archives better than this certificate?

The archive extract is an informative document, but not an expertise, it does not prove the authenticity or the value of the watch. It is, however, valuable, and if the seller has it, it is scanned into the Watch Certificate so that it is always accessible.

An invoice from a reputable vendor is enough?

The invoice indicates the selling price and the name of the professional. The Watch Certificate takes up these elements, adding high definition photos, details of 45 checkpoints, specifying the condition and authenticity, an estimate to date, the serial number, it is signed by a recognized expert and registered in a forgery-proof database.

In the second hand, why don't the brands authenticate the watches themselves?

It's not their job, the brands sell new watches. Some manufacturers do check watches, but they don't necessarily have the resources or the organization to do it at scale.

Why isn't this certificate initiated by the brands?

More and more brands are issuing digital certificates, but there is still no common standard.

Why not mark the watch with an engraving or a chip?

Absolutely all parts of a watch are replaceable so placing a marker inside is not viable.

Cases of use

This certificate is only useful for particularly rare watches?

It is always useful, whatever the watch, as long as it is valuable. It protects it and serves as evidence in case of theft.

If you're looking for a good deal, the certificate is an overkill?
