Setup
Before using your watch, please follow these steps to set the time and date.

- Setting the Calendar and Time:
- Pull the crown out to the First Gear position. Rotate the crown to adjust the calendar (date).
- Pull the crown out further to the Second Gear position. Rotate the crown to adjust the time. Push the crown back in completely to start the watch.

Operating Instructions
Chronograph Function (Stopwatch)
The CHENXI 908 watch includes a chronograph feature for measuring elapsed time.
- Start/Stop Stopwatch: Press the top pusher button to start the stopwatch. Press it again to stop.
- Reset Stopwatch: After stopping the stopwatch, press the bottom pusher button to reset the running second hand to zero. (Note: You must first press the running second hand to stop before resetting.)
The sub-dials indicate:
- Time Hand (24-hour display): One lap lasts 24 hours.
- Time Minute Hand: One lap is one hour.
- Second Hand: One lap is one minute.
Luminous Display
The watch features a luminous display, allowing you to read the time in low-light conditions. The pointers are covered with a luminous coating that absorbs light during the day and glows in the dark.

Maintenance
Water Resistance
Your CHENXI 908 watch is 3 ATM (30 meters) water resistant. This means it is suitable for daily use, such as hand washing, sweating, and light rain. It is NOT suitable for showering, swimming, diving, or any prolonged water immersion. Avoid operating the crown or pushers when the watch is wet.

Cleaning
To maintain the appearance of your watch, wipe the case and strap with a soft, dry cloth regularly. For the metal strap, a slightly damp cloth can be used, followed by immediate drying. Avoid using harsh chemicals or abrasive materials.
Battery Replacement
The watch is powered by a quartz movement and includes a battery. When the watch stops or the second hand begins to skip, it indicates that the battery needs to be replaced. It is recommended to have the battery replaced by a qualified watch technician to ensure the water resistance seal is maintained.
Troubleshooting
- Watch Not Running:
Check if the crown is fully pushed in. If it is, the battery might be depleted. Refer to the "Battery Replacement" section.
- Time is Inaccurate:
Ensure the crown is fully pushed in after setting the time. If the issue persists, the battery may be low, or the movement might require servicing.
- Chronograph Not Resetting to Zero:
Make sure the stopwatch function is stopped before attempting to reset. If it still doesn't reset, try stopping and resetting it a few times. If the problem continues, professional servicing may be needed.
- Condensation Under Glass:
This indicates a breach in the water resistance. Avoid further contact with water and seek professional repair immediately to prevent damage to the movement.
