Watches API

The engine room of horology, structured and queryable: 1,257 watch movements (calibers) across 320 brands, from the Rolex 3235 and Omega 8800 to vintage A. Schild and obscure quartz modules. Every caliber carries brand, caliber number, base caliber (what it derives from), movement type (automatic, manual, quartz...), in-house status, diameter and height in millimetres (vintage ligne sizes converted), jewel count, total parts, power reserve in hours, beat rate in vibrations per hour, complications/functions, known watch models that use it, a description and the complete raw spec sheet. Filter by brand, movement type, in-house status, minimum jewels, minimum power reserve or exact frequency; search by caliber number or the watch models a movement powers; browse the brand directory with country, founding year and Wikidata identifiers where matched. New and updated calibers flow in daily from the source's change feed; every record links back to its source page. Built for watch marketplaces, collector apps, service and repair tooling and horology content. Self-hosted dataset — no third-party calls at request time.
