Keep your watch collection at its best. Track overhaul and battery service, spot automatics that may have stopped, and get gentle reminders when service is due.
Keep your watch collection at its best.
"I forgot about an overhaul for years." "I pulled it out and it had stopped." Your watches deserve better — let WatchKeep look after their service and running.
■ Automatic service intervals by movement
Just pick automatic, manual, quartz or Spring Drive. WatchKeep estimates overhaul and battery-change timing and gently reminds you as it approaches.
■ Spot the ones that have stopped
Automatics stop when the power reserve runs out. From the last day worn, see "Running" or "May have stopped" — a nudge to wind it and set the time.
■ Your collection, in photos
Photograph each watch and the subject is cut out automatically. Your personal collection lined up beautifully.
■ Three-stage service reminders
Ahead of time (7 days, 1 day) → on the day → and gently every day after until it's checked. Never miss a service.
■ Tips for watch lovers
From magnetism and water resistance to not changing the date at night and lug widths — 24 tips and a mascot make caring for your collection more fun.
■ Widget support
See watches due for service and their status at a glance on your Home Screen.
