Maintenance
Cleaning Your Watch
- Wipe the watch case and band regularly with a soft, damp cloth.
- For stubborn dirt, use a mild soap solution and rinse thoroughly with clean water, then dry completely.
- Avoid using harsh chemicals, solvents, or abrasive cleaners, as these can damage the watch's finish and seals.
Battery Replacement
The watch battery typically lasts 18-24 months. When the display becomes dim or functions become erratic, it may be time to replace the battery. It is recommended to have the battery replaced by a professional watch technician to ensure the water resistance seal is properly maintained.
