Maintenance
Cleaning Your Watch
Wipe the watch case and band regularly with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying. Avoid using chemical cleaners, as they may damage the watch's finish or seals.
Water Resistance
This watch is water resistant up to 100 meters. This means it is suitable for swimming and snorkeling, but not for scuba diving. Do not operate any buttons while the watch is submerged in water. Ensure the crown is fully pushed in before exposing the watch to water.

Battery Replacement
When the digital display becomes dim or the watch stops functioning, the battery may need replacement. Battery replacement should be performed by a qualified watch technician to ensure the water resistance seal is properly maintained.
Storage
When not in use, store your watch in a cool, dry place away from direct sunlight and extreme temperatures. The original packaging can be used for safe storage.
Troubleshooting
- Analog hands not moving: Check if the crown is fully pushed in. If it is, the battery may be depleted.
- Digital display is blank or dim: The battery may be low or depleted. Replace the battery.
- Digital time is incorrect: Re-enter the digital time setting mode and adjust the time as per the 'Setup' section.
- Alarm not sounding: Ensure the alarm function is activated (check for the alarm icon on the display). Verify the alarm time is set correctly.
- Water inside the watch: Immediately take the watch to a professional watch repair service. Do not attempt to open the watch yourself, as this will void the warranty and likely cause further damage.
