Watch Keeper

For Collectors Who Take Their Watches Seriously Every watch tells a story. Watch Keeper helps you preserve it. Designed for enthusiasts who care about more than telling time, Watch Keeper is a powerful collection management app built around how serious collectors actually operate. Add watches by searching a global database of brands, models, and references, or enter details manually. Record everything from dial finish and lug width to purchase price and full service history. Attach photos, receipts, certificates, and insurance documents. Your entire collection, detailed down to the last complication. Privacy That Matches the Value of Your Collection Your data is encrypted on your device before it ever leaves your phone. Watch Keeper uses client-side encryption with a key only you control — we never see your collection data. Back up securely to Google Drive, Dropbox, or iCloud with confidence, knowing your information remains private even in the cloud. Track What Matters Wrist Time Monitoring Log wear sessions, track frequency, and see which watches get the time they deserve. Service History Document providers, costs, parts replaced, and warranties. Build a complete maintenance timeline. Timing Sessions Record timegrapher readings across positions. Track rate, amplitude, beat error, and regulation over time. Sell Smarter When it’s time to let a piece go, the Sale Post Generator creates formatted, platform-ready listings using your existing watch data.
