Scenario: By a window (Direct sunlight on a clear day)
Illuminance(lx): 30,000
Exposure Time: 6–8 hours
Charging Efficiency: ★★★★☆
Scenario: 30W Fluorescent Light
Illuminance(lx): 10,000

Set the bottom subdial watch hand at “60” first, then check the power reserve.
Sub-second hand Position Adjustment:
- Pull out the crown to position III.
Button A: Clockwise move
Button B: Counterclockwise move - Push the crown back to the position I.
Press button B for 2 seconds to display the current battery level. The small second hand automatically resets after 2 seconds.
Please note that if the sub-second hand does not point at "60", the power reserve indicator will be inaccurate.
Pull out the crown to position III and turn the crown to set the hour and minute hand. Push the crown back to the postion I.
To start, please confirm the crown is set at the position I, the sub-second hand (bottom subdial) is at “60”, and minute subdial hand (left subdial) is at “30”.
The stopwatch can measure up to 29’59’’ in one-second increments. When the measurement reaches 30 minutes, the stopwatch automatically stops counting.
The sub-second hand is capable of timing 60 seconds.
The minute subdial hand is capable of timing 30 minutes.

1. Release spring bars at the back by pushing the pin inward.
⚠ Spring bar is a small part, keep away from children and pets.
2. Replace the band.
3. Place one end of the spring bar into the lug hole, then insert spring bars by pushing the pin inward. Make sure the spring bars snap into the lug holes.
Move the buckle forward or backward to adjust the length. Attaching the clasp to the keeper completes the loop.
Additional tips for smaller wrist:
For smaller wrists, if the hook and clasp feel loose or insecure, adjust the case. To loosen, move the case away from the hook; to tighten, move it closer.

FAQ
This happens because the solar panel receives a large amount of energy in a short time, causing the indicator to react quickly. After several hours, the indicator may drop to a more accurate level as the energy stabilizes inside the rechargeable battery.
This is a normal characteristic of solar-powered watches and is not a defect in the movement or battery.
For a true full charge, we recommend exposing the watch to continuous strong light or sunlight for a longer period.
If you do not plan to use the watch for a period of time, please ensure it is charged before the battery level becomes completely empty. Keeping a minimum power reserve helps maintain stable performance and prolongs the lifespan of the rechargeable battery.
Solar watches require strong and consistent light exposure to store enough energy. Therefore, if the battery level is low, we recommend charging the watch under direct sunlight or near a window, which is far more efficient.
This is a normal characteristic of solar-powered watches and does not indicate any issue with the movement.
Placing the watch under direct light regularly ensures stable performance and optimal battery health.
This is a power reserve warning function built into many solar and quartz watches. It is designed to alert you that the watch needs to be recharged soon. The watch will continue to keep accurate time, but the battery should be charged to prevent it from stopping.
To restore normal operation, simply expose the watch to strong light or sunlight until it reaches a sufficient charge level. Once the battery is adequately charged, the second hand will return to normal one-second movement.
This is a normal feature and does not indicate any defect in the movement.
