The digital watch has three buttons for setting the time:
- Setting the clock: To set the clock, press the "H" button.
- Setting the minutes: press the "M" button
- Reset: Press the "R" button. This resets the minutes to ":00" to make it easier to set the desired time
If the "R" button is pressed between 10:30 and 11:29, the clock reading changes to 11:00, and between 11:30 and 12:29, it changes to 12:00.
