1. Press the MODE button repeatedly until the time display (hours, minutes, seconds) is shown.
2. Press and hold the MODE button for a few seconds until the hour digits start flashing.
3. Use the START/STOP button to adjust the hour.
4. Press the SPLIT/RESET button to move to the next setting (minutes, then 12/24 hour format, then month, date, day).
