Each city gets a clear label, airport-style abbreviation, and color, so you can spot London, New York, Tokyo, or home without doing the usual mental math. Choose the compact complication for a cleaner glance, or the dense one when you want more cities visible at once. Times update by the minute and stay easy to read, even when your wrist is only up for a second. Built for travelers, remote teams, long-distance friends, and anyone who just wants world time without opening a full app.
