Maintenance
Water Resistance:
The KXAITO 3311 watch is water resistant up to 5 ATM (50 meters). This means it is suitable for daily use, splashes, rain, and brief immersion in water. However, it is not recommended for swimming, diving, or prolonged water activities.
- DO NOT press any buttons while the watch is submerged in water.
- Avoid exposing the watch to hot water or steam, as this can damage the waterproof seals.
- Ensure the crown is fully pushed in before any contact with water.
Cleaning:
Wipe the watch case and band regularly with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by drying. Avoid using chemical cleaners or abrasive materials.
Battery Replacement:
When the display becomes dim or the watch stops functioning, the battery may need replacement. Battery replacement should ideally be performed by a qualified watch technician to ensure proper sealing and functionality.
