4. Maintenance and Care
4.1 Water Resistance
This watch is water resistant to 30 meters (100 feet). This means it can withstand splashes or brief immersion in water, such as during hand washing or light rain. It is not suitable for swimming, bathing, or diving. Do not operate buttons while the watch is wet or submerged.
4.2 Cleaning
To clean your watch, wipe it with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials, as these can damage the case or band.
4.3 Battery Replacement
The watch uses a Lithium Metal battery (included). While battery replacement is possible, it is recommended to have it performed by a qualified watch technician to ensure proper sealing and water resistance. Attempting to replace the battery yourself may void the warranty or compromise the watch's water resistance.
