5. Water Resistance Guidelines
This watch is rated for 50 meters (5ATM) water resistance. This means it is suitable for daily use, such as hand washing, rain exposure, and short periods of immersion in water. It is not suitable for showering with hot water, swimming, diving, or any water sports involving high-velocity water or significant depth.
- Do not operate buttons while the watch is submerged in water.
- Avoid exposing the watch to extreme temperature changes, which can compromise water seals.
- If the watch is exposed to saltwater, rinse it with fresh water and dry it thoroughly.
6. Maintenance
- Cleaning: Wipe the watch case and strap regularly with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying.
- Storage: When not in use, store the watch in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery: The watch uses a Japanese original battery designed for long life. When the display becomes dim or functions become erratic, it may be time for a battery replacement. This should ideally be performed by a qualified watch technician to maintain water resistance.
- Strap: The rubber strap is durable. Avoid contact with harsh chemicals or solvents that could degrade the material.
7. Troubleshooting

|---|---|---|
| Display is blank or dim | Low battery; Watch in power-saving mode | Press any button to activate. If still dim, replace battery. |
