Water Resistance
Your Diesel DZ4549 watch has a water resistance rating of 10 ATM (100 meters). This means it is suitable for swimming, snorkeling, and showering. However, it is not recommended for high-impact water sports or diving. Do not operate the crown or pushers while the watch is wet or submerged.

Battery Replacement
The watch is powered by a product-specific battery. When the battery runs low (indicated by dimming digital display or erratic analog movement), it is recommended to have it replaced by a qualified watch technician to ensure proper sealing and water resistance.
Troubleshooting
- Analog hands not moving: Ensure the crown is fully pushed in. If the issue persists, the battery may need replacement.
- Digital display blank or dim: The battery may be low. Replace the battery.
- Incorrect time/date: Refer to the 'Time and Date Setting' section to reset.
