3.5 Water Resistance

4. Maintenance
4.1 Cleaning Your Watch
Wipe the watch case and strap regularly with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying. Avoid using chemical cleaners, as they may damage the watch materials.
4.2 Battery Replacement
The watch uses two batteries: one for the analog movement and one for the digital display. When the display becomes dim or the watch stops functioning, battery replacement may be necessary. It is recommended to have batteries replaced by a qualified watch technician to ensure proper sealing and water resistance.
4.3 Strap Care
The watch features a durable resin strap. To prolong its life, avoid prolonged exposure to direct sunlight, extreme temperatures, and harsh chemicals. Inspect the strap periodically for signs of wear or cracking. If the strap shows significant damage, consider replacing it to prevent accidental loss of the watch.
