Winder - Watch Collection

Keep every watch service-ready.

Winder tracks service intervals, ownership history, and value for every watch you own — straps included — and shows you at a glance which pieces are fresh, due soon, or overdue. The only watch app with a live service-status ring on every piece, not just a list buried in a spreadsheet.

YOUR DATA. YOUR DEVICE. No account. No tracking. No third-party servers. Your collection lives on this device and syncs privately through your own iCloud — never through us. Export to CSV or JSON anytime, free. PDF collection sheets for insurance are part of Premium.

TRACK YOUR WHOLE COLLECTION • Watches — reference, movement, case specs, purchase details, warranty, notes • Straps — material, lug width, cost, and what's currently mounted on which watch • Service history — date, cost, service center, and work done, per watch • Value — purchase price, current estimate, and gain or loss over time

THE SERVICE RING, AT A GLANCE Every watch carries a thin ring that fills as its service interval elapses. Fresh, due soon, or overdue — oxblood the moment it's late. One glance across your whole vault tells you what needs attention.

SERVICE DASHBOARD Overdue pieces surface first, then what's due soon, then everything that's all clear. Log a service in a few taps — cost, shop, and notes — and the ring resets itself.

VALUE OVER TIME See your collection's total value, cost basis, and gain or loss, charted over time and broken down by brand and movement type. Know what your collection is actually worth, not just what you paid.

BUILT FOR COLLECTORS Whether you own one heirloom or a full collection, Winder gives it the considered home it deserves — light and dark, fast to use one-handed, and private by design.
