Operating
Water Resistance
This watch is 30M (3 ATM) water-resistant, meaning it is suitable for daily life activities such as hand-washing, sweat, and rain. It is not suitable for bathing, swimming, or diving. Avoid pressing any buttons underwater.

Luminous Dial
The watch features a luminous dial, allowing for easy time reading in low-light conditions. The luminosity depends on the watch's exposure to light; longer exposure to light results in a more noticeable glow in the dark.

Maintenance
To ensure the longevity and optimal performance of your LN LENQIN R015 watch, please follow these maintenance guidelines:
- Cleaning: Wipe the watch case and strap regularly with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials.
- Strap Care: The ultra-soft silicone strap is wear-resistant and breathable. Clean it with mild soap and water if necessary.
- Battery: The watch uses an imported Japanese quartz analog movement and battery, designed for long-term operation (more than a year). When the battery needs replacement, it is recommended to have it done by a professional watch technician to maintain water resistance.
- Avoid Extreme Conditions: Do not expose the watch to extreme temperatures, direct sunlight for prolonged periods, or strong magnetic fields.
- Water Exposure: As mentioned, avoid soaking in seawater, touching corrosive liquids, or hot water. Do not press buttons underwater.

Troubleshooting
- Watch Not Glowing in the Dark: Ensure the watch has been sufficiently exposed to light. The luminous material needs to absorb light to glow.
- Water Inside the Watch: If water appears inside the watch, immediately take it to a professional watch repair service. This may indicate a compromised seal, especially if the watch was exposed to conditions beyond its 30M water resistance rating (e.g., swimming, bathing, diving).
- Inaccurate Timekeeping: Check if the crown is fully pushed in. If the issue persists, the battery may need replacement or the movement may require servicing.
