Maintenance and Care
Water Resistance
This watch is water resistant up to 30 meters (3ATM), making it suitable for daily splashing and brief immersion in water. It is important to note that all watches cannot be bathed in hot water, as steam can penetrate the seals and damage the internal movement. Avoid pressing buttons or pulling the crown while the watch is wet.

Luminous Function
The watch features luminous hands, which utilize imported fluorescent powder to allow for easy time reading in low-light conditions or at night. For optimal luminescence, expose the watch to a light source before entering dark environments.

General Care

- Avoid exposing the watch to extreme temperatures (hot or cold) or sudden temperature changes.
- Keep the watch away from strong magnetic fields, as these can affect the accuracy of the quartz movement.
- The watch crystal is made of high-hardness coated glass, providing scratch and wear resistance. However, avoid direct impact to prevent damage.
