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. [Free] • Register up to 3 watches • Service reminders [Premium] • Unlimited watches • Group by winder, safe or case • Service log (type, shop, cost) • No ads One-time $20 or $1.49/week (no free trial). Subscriptions auto-renew and are billed to your Apple ID unless canceled at least 24 hours before the period ends. Cancel anytime in Settings. Service intervals and power reserves are general guides based on the movement. Adjust to your actual watch. ■ LINKS • Support: https://tsuzukit.com/contact/ • Terms of Service: https://tsuzukit.com/legal/terms-of-service.html • Privacy Policy: https://tsuzukit.com/legal/privacy-policy.html
