3.2 Water Resistance
This watch has a water resistance rating of 50 meters (5 ATM). This means it is suitable for short periods of recreational swimming, showering, or exposure to rain and splashes. It is not suitable for diving, snorkeling, or high-impact water sports. Avoid operating the crown while the watch is wet or submerged to prevent water intrusion.
4. Maintenance and Care
4.1 Cleaning
- Case and Crystal: Wipe the watch case and crystal with a soft, damp cloth. For stubborn dirt, a mild soap solution can be used, followed by rinsing with clean water and drying thoroughly.
- Stainless Steel Band: Clean the stainless steel band with a soft brush and mild soapy water to remove dirt and debris from the links. Rinse thoroughly and dry immediately to prevent water spots.
4.2 Battery Replacement
The watch is powered by one CR2 battery. When the watch stops or the time becomes inaccurate, the battery may need replacement. It is recommended to have the battery replaced by a qualified watch technician to ensure proper sealing and maintain water resistance.
4.3 General Care
- Avoid exposing your watch to extreme temperatures (hot or cold) or sudden temperature changes.
- Keep the watch away from strong magnetic fields, as these can affect the accuracy of the quartz movement.
- Avoid direct contact with solvents, detergents, perfumes, and cosmetics, as these can damage the case, band, or seals.
- Store your watch in a dry, safe place when not in use, preferably in its original packaging or a watch box.
