Maintenance
Proper care will help maintain the appearance and function of your watch.
- Cleaning: Wipe the watch regularly with a soft, dry cloth to remove dirt and moisture.
- Water Resistance: While water-resistant up to 10 ATM (330 feet), avoid operating the crown or pushers when the watch is wet or submerged to prevent water intrusion.
- Temperature: Avoid exposing your watch to extreme temperatures (hot or cold) or sudden temperature changes, as this can affect its accuracy and seals.
- Shocks: Protect your watch from strong impacts and vibrations.
- Battery Replacement: The watch uses 1 Lithium Ion battery. When the watch stops or the second hand moves erratically, it may be time for a battery replacement. It is recommended to have this done by a qualified watch technician to ensure water resistance is maintained.
