Maintenance
Cleaning
To clean your watch, wipe it gently with a soft, damp cloth. Avoid using harsh chemicals, solvents, or abrasive cleaners, as these can damage the case or strap.
Water Resistance
This watch has a water resistance rating of 3 BAR (30 meters). This means it is suitable for daily use, splashes, rain, and accidental immersion. It is not suitable for showering, bathing, swimming, snorkeling, or any water sports involving high-velocity water or prolonged submersion.
Do not operate the buttons while the watch is wet or submerged, as this can compromise the water resistance.
Battery Replacement
The watch uses one LR44 battery. When the display becomes dim or the watch stops functioning, it's time to replace the battery. Battery replacement should ideally be performed by a qualified watch technician to ensure proper sealing and maintain water resistance.
