5. Penyelenggaraan
- Pembersihan: Wipe the watch regularly with a soft, dry cloth. For the silicone strap, a mild soap and water solution can be used, followed by thorough rinsing and drying.
- Tahan Air: This watch is water resistant up to 30 meters (3 ATM). It is suitable for daily use, such as hand washing, rain, and splashes. It is bukan suitable for swimming, diving, or hot showers/baths, as steam and temperature changes can compromise seals. Ensure the crown is fully pushed in before any contact with water.
- Suhu: Avoid exposing the watch to extreme temperatures (hot or cold) or sudden temperature changes, which can affect accuracy and seal integrity.
- Medan Magnet: Keep the watch away from strong magnetic fields, as these can interfere with the quartz movement.
- Penggantian Bateri: When the watch stops or the second hand moves erratically, the battery may need replacement. This should be performed by a qualified watch technician to maintain water resistance.
