Maintenance
Water Resistance
Your Timex Sport Digital Watch is water resistant up to 200 meters (660 feet). This means it is suitable for recreational scuba diving. However, it is important to note the following:
- Do not press any buttons while the watch is submerged in water.
- Avoid exposing the watch to extreme temperature changes, which can affect its water resistance.
- After exposure to saltwater, rinse the watch with fresh water and dry it thoroughly.
Battery Information
The watch uses one Lithium metal battery (CR2025 cell). The battery is included with the watch. When the display becomes dim 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.
