Ensure the watch is correctly set. If the issue persists, the watch may require servicing or the battery might be low, affecting its accuracy.
Stopwatch or alarm not functioning
Ensure you are following the correct button sequences for activating the stopwatch or setting the alarm. Refer to the manual for precise instructions.
