4. Operating Your Watch
4.1 Luminous Function
The watch hands and markers are coated with a luminous material. After exposure to light, they will glow in the dark, allowing for easy time reading. The intensity and duration of the glow depend on the exposure time and intensity of light.

Figure 3: Luminous Display. This image shows the watch face with its hands and hour markers glowing brightly in a dark environment, demonstrating the luminous function.
4.2 Water Resistance
This watch is water-resistant to 30 meters (3ATM), meaning it can withstand splashes, rain, and brief immersion in water. It is not suitable for swimming, diving, or hot water activities (e.g., hot showers, saunas), as extreme temperature changes and steam can compromise the water seals.

- Cleaning: Wipe the watch case and strap regularly with a soft, dry cloth to remove dust and dirt. For the leather strap, avoid excessive moisture and harsh chemicals.
- Avoid Extreme Conditions: Protect your watch from extreme temperatures, direct sunlight for prolonged periods, and strong magnetic fields, which can affect accuracy.
- Chemicals: Avoid contact with solvents, detergents, perfumes, and cosmetic products, as they can damage the case, strap, or seals.
- Battery Replacement: The watch uses a high-quality battery with a life of up to 3 years. When the battery needs replacement, it is recommended to take the watch to a qualified watch technician to ensure proper sealing and function.
- Strap Care: The brown leather strap is designed for comfort and durability. To prolong its life, avoid prolonged exposure to water and sweat, and allow it to air dry if it gets wet.
