WatchLog: Service & Winder Log

WHAT IT DOES

WatchLog is a personal service log and winder rotation tracker for mechanical watch collectors. Built for people with 3 to 20 or more watches who want to track maintenance, accuracy, and rotation without a spreadsheet.

- Watch registry. Brand, model, reference number, movement, case material, water resistance, serial number, purchase date and price, current value estimate. Cover photo plus extras for dial, papers, and receipt.
- Service log. Per watch: date, service type (full service, pressure test, strap change, regulation, crystal replace, or other), service provider, cost in any currency, notes, and photos of the service record.
- User-set service intervals. Default 5 years between full services, 1 year for pressure tests, fully editable per watch. Service intervals are targets you choose, not manufacturer-mandated.
- Service-due reminders. Optional notifications 30 days before each watch's next target service date.
- Accuracy log with trend chart. Record seconds-per-day deviation over time. The chart shows when a watch starts drifting and might need regulation.
- Wear log. A lightweight "wore today" stamp per watch. Long-press a card on the Collection screen.
- Winder registry + rotation schedule. Declare your winders, assign watches to slots with direction and TPD, and set a rotation cadence reminder. Past rotation history is preserved.
- PDF service-history report. One-tap export of a per-watch report with registry info, full service log, accuracy entries, and embedded photos. Useful for resale provenance, insurance, or handing off to a new watchmaker.
- Local backup and restore. Export everything as a single zip file you can save to Drive, Dropbox, or email.
- Multi-currency from day one. Each amount carries its own ISO currency code. No silent FX conversions.

WHO IT IS FOR

- Mechanical, automatic, and manual watch collectors
- People who own 3 or more watches and want a single record of every service visit, regulation, and rotation
- Vintage and pre-owned buyers who want a provenance report ready when they sell
