High-Quality Data - "Apples-to-Apples" Comparison

Many offerings today show market prices without explaining their basis and ignore differences in dial configurations among vintage watches with the same reference number, leading to potentially misleading price averages.

To address this, we carefully document the specific configuration of each watch on the server side, including dial color, watch indices, calendar language, types of gems used, cloisonné enamel scenes, etc.

Challenges In Valuing Vintage Watches

We acknowledge the fluctuation in the market price of vintage watches, influenced by factors such as condition, rarity and provenance. Therefore, the indicative results we furnish for vintage timepieces are shaped by the specific criteria inserted by our users, encompassing elements like the presence of box and papers, a certificate or origin, or an extract from the archives, etc.

Data Source

We gather data from six prominent auction houses - Phillips, Sotheby’s, Christie’s, Antiquorum, Monaco Legend Auctions, and Bonhams - while excluding private watch dealers due to lack of publicly available data and regional transaction result inconsistencies.
