Watch Log & Collection - Crown

The collector's journal — catalog your watches, track service history, log wrist time, and know exactly what your collection is worth.

Crown is the collector's journal for serious watch enthusiasts. Document your entire collection, track service history, log wrist time, and monitor your collection's value - all in one beautifully crafted app.

CATALOG YOUR COLLECTION Every watch documented with brand, model, reference number, caliber, complications, purchase date, purchase price, and current value estimate. Add photos, personal notes, and the story behind each piece. Your collection, curated to museum standards.

NEVER MISS A SERVICE Mechanical watches require service every 3-7 years. Crown tracks every service event and alerts you when watches are approaching or overdue. Log full services, bracelet adjustments, battery replacements - every visit to the watchmaker recorded.

WRIST TIME TRACKING See exactly which watches you wear most and least. Log your daily wear with a single tap and watch a gold calendar fill in over 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 your total collection value, individual gain/loss on each piece, and shows you how your collection's worth has grown. No external market data - your valuations, your privacy.
