- The light will remain on for a few seconds before automatically turning off.
4. Maintenance
4.1. Water Resistance
Your Timex T80 watch is water resistant to 30 meters (100 feet). This means it can withstand splashes or brief immersion in water. However, it is not suitable for swimming, bathing, or diving. Avoid pressing buttons while the watch is wet to prevent water entry.
4.2. Cleaning Your Watch
To maintain the appearance of your watch:
- Wipe the watch case and bracelet with a soft, damp cloth.
- For stainless steel bracelets, a mild soap solution can be used, followed by thorough rinsing and drying.
- Avoid using harsh chemicals, abrasive cleaners, or solvents, as these can damage the watch's finish.
4.3. Battery Replacement
The Timex T80 requires 1 Lithium Metal battery (CR2016). 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 proper sealing and water resistance.
