4. Maintenance
4.1. Water Resistance
Your watch has a water resistance rating of 5 ATM (50 meters). This means it is suitable for everyday use, such as showering or brief immersion in water. It is not suitable for swimming, diving, or prolonged water activities. Always ensure the crown is fully pushed in before any contact with water.
4.2. Cleaning
To maintain the appearance of your watch, wipe the case and strap regularly with a soft, dry cloth. For the mesh strap, a soft brush can be used to remove dirt from the links. Avoid using harsh chemicals or abrasive materials.
4.3. Battery Replacement
The watch is powered by a quartz movement. When the battery needs replacement, it is recommended to take your watch to an authorized service center or a professional watchmaker to ensure proper handling and maintain water resistance.
4.4. Sapphire Glass Care
The sapphire crystal is highly scratch-resistant but not entirely scratch-proof. Avoid direct impact and contact with extremely hard or sharp objects to prevent damage.

5. Troubleshooting
- Watch not running: Check if the crown is fully pushed in. If the watch still does not run, the battery may need replacement.
- Time/Day incorrect: Refer to section 2.1 for instructions on setting the time and day.
- Chronograph hands not resetting to zero: If the chronograph hands do not return to their zero position after pressing the lower pusher, a recalibration may be needed. Consult an authorized service center.
- Condensation under the crystal: This may indicate a loss of water resistance. Avoid further contact with water and seek professional service immediately.
