Maintenance
- Cleaning: Wipe the watch case and band with a soft, damp cloth. For stubborn dirt, use a mild soap solution and rinse thoroughly with clean water. Avoid harsh chemicals or abrasive cleaners.

- Temperature: Avoid exposing the watch to extreme temperatures (hot or cold) for extended periods, as this can affect battery life and accuracy.
- Impact: While the watch is shock-resistant, avoid unnecessary impacts or drops to prevent damage to internal components or the crystal.
- Battery Replacement: The watch uses a long-life battery (typically over 2 years). When the display becomes dim or functions become erratic, it may be time for a battery replacement. It is recommended to have the battery replaced by a qualified watch technician to ensure proper resealing and maintain water resistance.
