About

The Watchmakers App is an iPhone and iPad app 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. • Identify any movement by photo against our industry-leading proprietary database using a deep-dive, logic-driven process that outperforms guessing AI, giving you manual-grade precision and total control at every step. • 100+ search filters, including manufacturer, country, power source, complications, escapement, shape, balance position, and more, for quick identification of the movement. • More than 1,000 technical data sheets from original manufacturers, parts interchangeability information from Jules Borel, BestFit, Boley, Flume 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. • Closely integrated with the largest horological trademarks database, mikrolisk.de, offering a quick search within the app of 65,000+ hallmarks to find more historical context for vintage movements. • Offers the most comprehensive lists for many manufacturers' movements, including Rolex, Patek Philippe, and many others, as well as the most comprehensive U.S. import codes list.
