5. Maintenance
5.1 Water Resistance
Your CALYPSO K5801/4 watch is water-resistant up to 100 meters (10 ATM). This means it is suitable for swimming, snorkeling, and showering. However, it is not recommended for scuba diving. Do not operate buttons underwater, as this can compromise the water seal.
5.2 Cleaning
To clean your watch, wipe it with a soft, damp cloth. For stubborn dirt, a mild soap solution can be used, followed by rinsing with clean water and drying thoroughly. Avoid using harsh chemicals or abrasive materials, as these can damage the case and strap.
5.3 Battery Replacement
When the display becomes dim or functions become erratic, it may be time to replace the battery. Battery replacement should be performed by a qualified watch technician to ensure the water resistance seal is properly maintained.
