Maintenance
Cleaning Your Watch
- Wipe the watch case and strap with a soft, damp cloth.

- Ensure the watch is completely dry before wearing.
- Avoid using harsh chemicals, solvents, or abrasive cleaners, as these can damage the watch's finish and seals.
Water Resistance Guidelines
Your watch is water resistant up to 10 meters (1 ATM). This means it is suitable for splashes, rain, and brief immersion in water.
- Do NOT press any buttons while the watch is submerged in water.
- Do NOT use the watch for diving, snorkeling, or high-pressure water activities.
- After exposure to saltwater, rinse the watch with fresh water and dry it thoroughly.
