5. Maintenance

Proper care ensures the longevity and performance of your watch.

5.1 Water Resistance Care

The watch is water-resistant to 50 meters (5 ATM). To maintain its water resistance:

• Rinse the watch with fresh water after exposure to saltwater.
• Avoid pressing buttons underwater.
• Prevent thermal shock by avoiding sudden temperature changes (e.g., hot showers immediately after cold water exposure).

5.2 Battery Information

The watch uses 1 Nonstandard Battery (included) with an approximate battery life of 18 months. When the battery is low, the display may dim or functions may become erratic. Battery replacement should ideally be performed by a qualified technician to ensure water resistance is maintained.

5.3 Cleaning

Clean the watch case and strap regularly with a soft, damp cloth. For the nylon strap, mild soap and water can be used, ensuring it is thoroughly dried afterward.
