You can set the time in two ways: You can adjust analog time on LunaR watch with the crown and digital time through LunaR iOS & Android mobile app.
1. Set time on the watch to match time of local timezone by gently pulling out the crown and turning clockwise. The analog time is manually set and it does not automatically sync.
2. Lunar also has a digital time (checking it by single pressing the right button). Under Settings--Digital Time, you could choose which time to show for digital time, Local Time or Home Time. Local time will be synced to your phone time. Home Time will be synced to the Home City you set in the app--Settings.
