Maintenance
Water Resistance:
The SKMEI 1637 watch is rated for 50 meters (164 feet) water resistance. This means it is suitable for swimming, washing hands, and showering. However, it is crucial not to press any buttons while the watch is submerged in water, as this can compromise the water seal and lead to damage.
General Care:
- Clean the watch regularly with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by drying.
- Avoid exposing the watch to extreme temperatures, direct sunlight for prolonged periods, or strong magnetic fields.
- Keep the watch away from harsh chemicals, solvents, and detergents, as these can damage the case and strap materials.
- If the watch comes into contact with saltwater, rinse it with fresh water and dry thoroughly.
