Operating the Chronograph
Your watch is equipped with a chronograph function for measuring elapsed time.
1. Basic Timekeeping
The main hands display the current time. The small sub-dials are used for the chronograph function and a 24-hour indicator.
2. Using the Chronograph
- Start: Press the upper pusher (A) to start the chronograph. The chronograph second hand will begin to move.
- Stop: Press the upper pusher (A) again to stop the chronograph. The elapsed time will be indicated by the chronograph hands.
- Reset: After stopping, press the lower pusher (B) to reset the chronograph hands to their zero positions.
Maintenance
1. Cleaning
Wipe the watch case and bracelet regularly with a soft, dry cloth. For stubborn dirt, use a soft brush and mild soapy water, then rinse thoroughly with fresh water and dry completely. Ensure the crown is pushed in before cleaning with water.
2. Water Resistance
This watch has a water resistance rating of 50 meters (5 ATM). This means it is suitable for short periods of recreational swimming, but not for diving or prolonged water immersion. Always ensure the crown is fully pushed in to maintain water resistance.

3. Solar Cell Care
To maintain the solar cell's efficiency, avoid prolonged storage in dark places. Regular exposure to light will keep the watch charged and functioning correctly. If the watch is stored in darkness for an extended period, it may require a full recharge.
Troubleshooting
- Watch Not Running: If the watch stops, expose it to bright light for several hours to recharge the solar cell. If it still does not run, consult a service center.
- Chronograph Hands Not Resetting to Zero: If the chronograph hands do not return to the zero position after resetting, refer to the detailed manual for specific calibration instructions or contact customer support.
- Date Not Changing: Ensure the time is set correctly, especially the AM/PM cycle. The date typically changes around midnight.
