Care and Maintenance
- Cleaning: Wipe the watch regularly with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying. Avoid harsh chemicals or abrasive materials.
- Water Resistance: This watch is rated for 100 meters (10 ATM) water resistance. This means it is suitable for swimming and snorkeling, but not for scuba diving. Do not operate buttons or the crown while the watch is wet or submerged.
- Temperature: Avoid exposing the watch to extreme temperatures (hot or cold) or sudden temperature changes, as this can affect its accuracy and seals.
- Impact: Protect the watch from strong impacts or drops.
- Battery Replacement: When the digital display dims or the analog movement stops, the battery may need replacement. It is recommended to have battery replacement performed by a qualified watch technician to ensure water resistance is maintained.
