The Watchmakers App

The Watchmakers App is for quickly identifying, researching, and comparing watch movements and parts.

Access the most reliable, detailed, structured, and searchable information on 12,000+ watch calibers, interlinked with tens of thousands of watch parts.

More than 1,000 technical data sheets from original manufacturers, parts interchangeability information from Jules Borel, and GR mainsprings information in collaboration with Generale Ressorts, linked directly to the related caliber infosheets.

Thanks to subscribers to the paid plans, the data in the app is continuously updated and improved with verified data from catalogs, manufacturers, archives, and experts — ensuring the information you rely on stays accurate and current. This commitment to accuracy is what really separates this app from other available watch movement databases.

Offers the most comprehensive lists for many manufacturers' movements, including Rolex, Patek Philippe, and many others.
