UTC Face: World Clock puts a city's time on your Apple Watch face in type large enough to read at a glance. The built-in world clock complication is small. This one uses the whole slot: the city's three-letter code, its UTC offset, and the time — in the same large, rounded, monospaced face as your watch's own clock. HOW IT WORKS • Edit your watch face and add UTC Face to a large rectangular complication slot — Modular Duo, Modular, Infograph Modular, or any face with one. • Tap the slot again to choose which city it shows. • Put a second one in the other slot for a different city. YOUR CITY LIST • Manage your cities in the iPhone app: add, remove, reorder. • Changes sync to your watch automatically. • 50 built-in cities covering every major time zone, available offline. • Unlimited online search for anywhere else. • UTC is always there. ACCURATE • Updates on the minute, aligned to the minute boundary — no drift. • Daylight saving changes are handled automatically for every city. PRIVATE • No accounts, no analytics, no ads. • Your city list stays on your devices. There is no server. Requires iOS 26 and watchOS 26.
