4. Maintenance
4.1 Water Resistance
This watch is water resistant up to 5 ATM (50 meters). This means it is suitable for everyday use and can withstand splashes, rain, and brief immersion in water. It is not suitable for swimming, showering, or diving. Avoid operating the crown or pushers when the watch is wet to prevent water ingress.
4.2 Strap Care
The genuine leather strap should be kept dry and clean. Avoid prolonged exposure to direct sunlight, extreme temperatures, and moisture, which can cause the leather to crack or discolor. Clean with a soft, damp cloth if necessary and allow to air dry completely.

4.3 Battery Replacement
The watch is powered by a quartz movement requiring a battery. When the battery runs low, the watch may stop or the second hand may jump in irregular intervals. Battery replacement should be performed by a qualified watch technician to ensure proper sealing and water resistance.
5. Troubleshooting
5.1 Watch Not Running
If the watch is not running, check if the crown is fully pushed in. If it is, the battery may need replacement. Contact customer support or a certified watch repair center.
5.2 Incorrect Time Display
If the time is incorrect, follow the instructions in Section 2.1 to reset the time. If the issue persists, the movement may require inspection by a professional.
