Maintenance
1. Water Resistance
This watch is water resistant to 100 meters (10 ATM). This means it is suitable for swimming and snorkeling, but not for scuba diving. Always ensure the crown is fully pushed in before exposing the watch to water. Do not operate the crown or buttons while the watch is wet or submerged.
2. Cleaning
- Wipe the watch case and crystal with a soft, dry cloth.
- For the leather band, wipe gently with a slightly damp cloth and allow it to air dry completely. Avoid excessive moisture, direct sunlight, and harsh chemicals, which can damage the leather.
- If the watch has been exposed to saltwater, rinse it with fresh water and dry thoroughly.
3. Battery Replacement
The watch uses an SR621SW battery with an approximate life of 2 years. When the battery runs low, the second hand may start moving at two-second intervals. It is recommended to have the battery replaced by a qualified watch technician to ensure proper sealing and maintain water resistance.
4. General Care
- Avoid exposing the watch to extreme temperatures, strong magnetic fields, or strong vibrations.
- Keep the watch away from solvents, detergents, perfumes, and cosmetics, as these can damage the case, band, or gaskets.
