Maintenance and Care
Water Resistance
The SKMEI 1339 watch is water-resistant up to 50 meters (5 ATM). This means it is suitable for showering, swimming in shallow water, and general water exposure. It is not suitable for diving, snorkeling, or exposure to hot water (e.g., hot tubs, saunas) as steam can penetrate the seals. Do not operate buttons while the watch is wet or submerged.
Battery Replacement
The watch uses a Japanese battery for reliable power. When the display dims 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 proper sealing and maintain water resistance.
Cleaning
To clean your watch, wipe it with a soft, damp cloth. Avoid using harsh chemicals, solvents, or abrasive cleaners, as these can damage the watch case or strap.
Troubleshooting
- Watch not functioning or displaying incorrect time: Check if the battery needs replacement. If recently replaced, ensure it was installed correctly. Try resetting the watch by pressing all four buttons simultaneously for a few seconds (if applicable, consult a technician if unsure).
- Buttons not responding: Ensure the watch is not wet. If the issue persists, there might be a mechanical fault; contact support.
- Pedometer readings are inaccurate: Ensure the watch is worn snugly on your wrist. Movement during driving or other non-walking activities can sometimes be misinterpreted as steps.
- Display is dim: The battery may be low. Replace the battery.
