How do I replace the battery?
Battery replacement should be done by a professional to maintain water resistance. Use a CR2025 battery. Open the back cover, remove the old battery, insert new one with positive side up, and replace the cover securely.
Why is my watch not showing the correct date?
The calendar is pre-programmed until 2099. Ensure you set the correct year. If the date is off, reset the time and date following the setting procedure. If the problem persists, the battery may be low.

In normal timekeeping mode, press and hold ST/SP for 3 seconds to toggle between 12-hour and 24-hour format. The indicator changes accordingly.
What does the 'SNZ' indicator mean?
SNZ stands for Snooze. When the alarm sounds, press any button to activate snooze. The alarm will sound again after about 5 minutes. The indicator appears when snooze is active.
How do I clean my watch?
Use a soft, dry cloth to clean the case and band. For deeper cleaning, remove the band and wash with mild soap and water, then dry thoroughly. Avoid using chemicals or abrasives.
What does the 'CHG' indicator mean?
Some models have a 'CHG' indicator when the battery is low. If you see this, the battery needs replacement soon. The watch may function intermittently until replaced.
