Set the time and date
- From the Timekeeping Mode, press B three times to reach the Time Setting Mode; the seconds flash.
- Press C to reset the seconds to 00.
- Press A to move through the settings: seconds, hour, minutes, month, day, day of the week.
- On any setting other than the seconds, press C to advance it (hold for fast).
- Press B to go back to the Timekeeping Mode.
Good to know
Resetting the seconds between 30 and 59 adds one minute.
In the Timekeeping Mode, press C to switch between 12-hour and 24-hour format. The watch ignores leap years, so set February 29 by hand.
