Create a watch in the Atelier, inspect its moving mechanism, or try a motion-responsive ocean dial. Use your chosen design with timers and reusable alarms.
Create a watch you can turn, inspect and use while you time your day. Crown & Chime combines an interactive 3D watch collection with a local watch-design Atelier, a timer and reusable alarms.
In the Atelier, combine case, dial, hand, bracelet, caseback and movement options. Name a design, save it to your watch box and return to edit or wear it. Try the Living Ocean dial: its water surface tilts and ripples as you move your iPhone.
Explore fifteen watch studies with rotating views, zoom and animated hands. Inspect display-back mechanisms or use the working chronograph, with start/stop and reset pushers and a tachymeter calculation.
Set a countdown, pause or resume it, and view the dial while it runs. Save one-time, specific-date or repeating alarms. Use the system alert or record a personal alarm sound on your device. A timer Live Activity supports checking the countdown outside the app.
No account, advertising, analytics or subscriptions. Watch assets and saved designs stay on your device. Optional bug reports are reviewed by you before you send them.
Requires iOS 26.1 or later. One countdown timer at a time. Alarm and microphone access are requested when needed. Watch studies are unaffiliated with watch manufacturers; they are not official watch products.
