ການປ່ຽນແບັດ

The watch is powered by one SR920SW battery, which has an approximate lifespan of 3 years. When the watch stops or the second hand moves erratically, it indicates a low battery. Battery replacement should be performed by a qualified watch technician to ensure proper sealing and water resistance.

• Have the water resistance gaskets checked and replaced every 2-3 years, especially if the watch is frequently exposed to water.
• Avoid exposing the watch to extreme temperature changes, which can affect the water resistance seals.
