Penyelenggaraan dan Penjagaan
Hayat Bateri
This watch is equipped with a 10-year battery (CR2025). While designed for longevity, actual battery life may vary depending on usage frequency of features like the illuminator light and alarms. When the display becomes dim or functions become erratic, it may be time for a battery replacement. It is recommended to have battery replacement performed by an authorized service center.
Tahan Air
The watch is rated for 200-meter (660 feet) water resistance. This means it is suitable for recreational swimming, snorkeling, and diving. However, it is not designed for saturation diving. Do not operate buttons while the watch is wet or submerged to prevent water ingress. Avoid exposing the watch to hot water or steam, as this can compromise the water resistance seals.

- Wipe the watch case and band with a soft, dry cloth regularly.
- For resin bands, you can use a mild soap solution and a soft brush, then rinse thoroughly with clean water and dry completely.
