5. Water Resistance Guidelines
Your OLEVS watch is rated 3ATM (30 meters / 100 feet) water-resistant. This means it is suitable for:
- Daily use
- Splashes
- Rain exposure
It is NOT recommended for:
- Swimming
- Bathing or showering (especially with hot water, which can cause fogging)
- Diving or snorkeling
- Operating buttons underwater
Always ensure the crown is fully pushed in to maintain water resistance. Exposure to hot water or steam can compromise the watch's seals.

6. Maintenance and Care
- Cleaning: Wipe the watch case and strap regularly with a soft, dry cloth to remove dust and dirt. For leather straps, avoid excessive moisture.
- Avoid Chemicals: Do not expose the watch to solvents, detergents, perfumes, or cosmetics, as these can damage the case, strap, or seals.
- Temperature Extremes: Avoid exposing the watch to extreme temperatures (hot or cold) or sudden temperature changes, which can affect the movement and water resistance.
- Magnetic Fields: Keep the watch away from strong magnetic fields (e.g., speakers, refrigerators, mobile phones) to prevent interference with the quartz movement.
- Impact: Protect the watch from strong impacts or drops.
- Battery Replacement: When the watch stops or the second hand moves erratically, it indicates a low battery. Have the battery replaced by a qualified watch technician to ensure proper sealing and function.
