Your personal collection lined up beautifully. ā–  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. ā–  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. ā–  Widget support See watches due for service and their status at a glance on your Home Screen.
