4. Maintenance and Water Resistance
4.1 Water Resistance (50M / 5 ATM):
The CakCity Model 2192 watch is water-resistant up to 50 meters (5 ATM). This means it is suitable for light swimming, showering with cold water, and general daily use where it may be exposed to splashes or rain.
- Do NOT press any buttons while the watch is submerged in water.
- Avoid exposure to hot water, steam, or saunas, as this can compromise the watch's seals.
- After exposure to saltwater, rinse the watch with fresh water and dry thoroughly.

4.2 Cleaning:
Wipe the watch case and strap regularly with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials that could damage the watch's finish.
4.3 Battery Replacement:
The watch uses a CR2025 battery. When the display becomes dim or functions become erratic, it may be time to replace the battery. It is recommended to have the battery replaced by a qualified watch technician to ensure proper sealing and maintain water resistance.
5. Troubleshooting
- Display is blank or dim: Check the battery. If the battery is low, replace it. Ensure the watch has not been exposed to extreme temperatures.
- Time is incorrect: Re-set the time and date following the instructions in Section 2.1. If the time consistently drifts, the battery may be low or the watch may require service.
- Buttons are unresponsive: Ensure the watch is not in a locked mode (if applicable, though this model does not specify one). Try a soft reset by pressing all four buttons simultaneously for a few seconds (if this does not work, consult a professional).
- Water inside the watch: If condensation or water droplets appear inside the watch, stop using it immediately and take it to a professional for inspection and repair to prevent further damage.
