Maintenance
Water Resistance
This watch is water resistant to 30 meters (100 feet). This means it can withstand splashes or brief immersion in water. It is not suitable for swimming, bathing, or diving. Avoid pressing buttons while the watch is wet to prevent water ingress.
Crystal Care
The watch features an acrylic lens. Acrylic crystals are durable but can be prone to scratches. To maintain clarity, avoid contact with abrasive surfaces. Minor scratches can often be buffed out with specialized acrylic polish.
Battery Information
The watch is powered by 1 Lithium Metal battery (included). When the display dims or functions become erratic, it may be time to replace the battery. Battery replacement should ideally be performed by a qualified watch technician to ensure water resistance is maintained.

Troubleshooting
Display is blank or dim
- Check the battery. A low battery can cause a dim or blank display. Replace the battery if necessary.
- Ensure the watch is not exposed to extreme temperatures, which can affect LCD performance.
Buttons are unresponsive
- Ensure the watch is dry. Water or moisture can sometimes interfere with button operation.
- If the issue persists, a reset may be required. Refer to the full instruction manual for specific reset procedures or contact customer support.
Time is inaccurate
- Re-set the time and date as described in the 'Setup' section.
