Maintenance
1. Cleaning
Regularly clean your watch with a soft, damp cloth. Avoid using harsh chemicals, solvents, or abrasive materials, as these can damage the watch case, crystal, or strap.
2. Water Resistance
This watch is water resistant up to 50 meters (5 ATM). It is suitable for short periods of recreational swimming but is not designed for diving or snorkeling. To maintain water resistance, avoid pressing any buttons while the watch is submerged in water.
3. Battery Replacement
The watch is powered by a CR2025 cell battery. When the display dims, functions become erratic, or the watch stops operating, the battery may need replacement. It is highly recommended to have the battery replaced by a qualified watch technician to ensure proper sealing and maintain the watch's water resistance.
