It is not designed for scuba diving or high-impact water sports. Avoid operating buttons while the watch is wet or submerged to prevent water entry.

Maintenance

Proper care will ensure the longevity and performance of your watch.

• Cleaning: Wipe the watch regularly with a soft, dry cloth. For stubborn dirt, use a soft cloth dampened with water and mild soap, then wipe dry.
• Battery Replacement: The watch features a 10-year battery. When the display becomes dim or functions become erratic, it may be time for a battery replacement. It is recommended to have the battery replaced by a qualified watch technician to ensure water resistance is maintained.
• Temperature Exposure: Avoid exposing the watch to extreme temperatures (hot or cold) for prolonged periods, as this can affect battery life and accuracy.
• Chemicals: Keep the watch away from gasoline, cleaning solvents, aerosols, adhesives, paints, etc. These can cause discoloration or damage to the resin case and band.
