From Seiko to Rolex, Tudor to Tissot - Crown tracks every timepiece. Log wrist time, service history, and collection value. Built for serious horologists.
Crown is the watch tracker built for serious collectors and horologists. Document your entire collection, track every service, log wrist time, and monitor what your timepieces are worth - from everyday Seiko and Casio to rare Rolex and Breitling.
CATALOG YOUR COLLECTION
Every timepiece documented exactly: brand, model, reference number, caliber, complications, purchase date, purchase price, and current value estimate. Add photos, notes, and the story behind each watch. Rolex, Tudor, Tissot, Hamilton, Citizen, Breitling, Casio, chronographs, dive watches - Crown handles every category your collection spans.
NEVER MISS A SERVICE
Mechanical watches need service every 3-7 years. Crown tracks every service event and alerts you before watches are overdue. Log full services, bracelet adjustments, battery replacements - every watchmaker visit recorded and searchable.
WRIST TIME TRACKING
See exactly which watches you wear most and least. Log daily wear with a single tap and watch a gold calendar fill across the month. Wearing distribution analytics show your rotation habits at a glance (Crown Pro).
COLLECTION VALUE
Enter purchase prices and current estimates for every watch. Crown calculates total collection value, individual gain/loss per piece, and how your collection's worth has changed over time. Your valuations, your privacy - no external market data feeds.
AI WATCH CONSULTANT (Crown Pro)
Expert guidance powered by AI trained on horology. Ask about service intervals, movement specifications, bracelet compatibility, buying advice, and the history of any timepiece - from the mechanics of a chronograph to the lore of a vintage Rolex. Like having a master watchmaker in your pocket.
