50 years of watch and jewelry technology to distinguish authenticity
CONTÉVANOU has been involved in watch and jewelry technology for 50 years. We always strive to buy and trade in at the right price.
We take the time to assess your property and offer the best price
Proceeding with a trade-in by quickly verifying authenticity is not necessarily a bad thing.
However, if you are not in a hurry, we recommend a thorough appraisal , as it takes time to determine the true value of an item.
It is our policy to thoroughly verify authenticity and appraisal, and to pay the highest possible price .
Watch Trade-In Program
As an authorized dealer of watches and jewelry, CONTÉVANOU does not display purchased or traded-in items in stores , but instead repairs and inspects them before distributing them to domestic and international markets (auctions, etc.).
Since it can be sold to enthusiasts all over the world, it is easy to get a high appraisal .
If you have the warranty, box, accessories, and extra links, we can increase the appraisal value . It is also fine if the accessories are missing or the item is in working condition.

Compliant with EU waste law standards
In order to comply with France's waste laws, we at Boutique CONTÉVANOU donate a portion of our sales to CITEO (an organization promoting the circular economy).
German government's contribution to nature conservation
We at CONTÉVANOU donate a portion of our sales to the German government's waste reduction initiative, and aim to further reduce waste. We believe that protecting the natural environment of the world is not just a matter of corporate ethics, but is also a natural act even if you live in Japan.
Products sell, concepts don't.
The philosophy of CONTÉVANOU, an authorized watch and jewelry dealer, is
The idea is that "you can sell a product, but you can't sell the philosophy behind it."
We will reexamine what it means to be a proper retail store based on Japanese law and faithfully abide by it.
On top of that, we don't just sell products, we value proposals that lead to experiences and value = "things,"
We continue to search for the "things" that will bring about these "events."
We are a small business, and that's why we strive to provide the most ethical service possible.
Everything we can do as a small business.
As a small retailer, our primary goal is to contribute to society .
We will comply with Japanese laws and conduct business honestly with proper ethics.
We will continue to strive to connect old and new cultures, and instead of pursuing excessive profits, we will devote our time and effort to creating new value for the region.
We also pledge to use things for a long time, take good care of them, and reduce waste through repair and recycling, contributing to the circulation of technology and art.
