Maintenance
1. Cleaning Your Watch
To maintain the appearance of your watch, wipe it regularly with a soft, dry cloth. For stainless steel bands, a slightly damp cloth can be used, followed by immediate drying. Avoid using harsh chemicals or abrasive materials.
2. Water Resistance
This watch is rated 30M water resistant. This means it can withstand splashes, rain, and brief immersion in water (e.g., hand washing). It is not suitable for swimming, diving, or showering with hot water, as steam can penetrate the seals. Ensure all buttons are not pressed while the watch is wet.

3. Battery Replacement
The watch uses a standard watch battery (CR2025, as indicated on the case back). When the display dims or functions become erratic, it may be time to replace the battery. It is recommended to have the battery replaced by a qualified watch technician to ensure proper sealing and maintain water resistance.
