## What is WatchKeep?

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.
