Setting the time

If the chronograph is running, press Button A to stop it, then set the hands back to “0” (12 o’clock) position if they aren’t already.
Pull the crown out to the second click (time-setting). The second hand will stop.
Rotate the crown to set hour and minute. Make sure the 24-hour dial matches AM/PM.
Push the crown back to the normal (pushed-in) position. If your model has a screw-down crown, ensure it’s screwed in to maintain water resistance.

Setting the Date

1. Pull the crown out to the first click.
2. Rotate the crown clockwise to advance the date. Avoid setting the date between 9:00 PM and 1:00 AM, as this may interfere with the date change mechanism.
3.Push the crown back to the normal position.

Using the Chronograph

Start/Stop measurement: Press Button A.
Reset to zero: First stop the measurement with Button A, then press Button B.
The stopwatch measures in 1-second increments, up to 60 minutes.

Zeroing the chronograph hands

If any chronograph hand does not return to the 12 o’clock (“0”) position after reset:

Pull the crown out to the second click.
Use Button A (or Button B/combination depending on model) to adjust the mis-aligned hand(s) until they point to zero.
Push the crown back in and perform a stop → reset to confirm all hands return to zero.

Standard Maintenance & Precautions

Always push the crown back in after setting to preserve water-resistance.
Do not change the date when the watch time is between 9 PM and 1 AM.
After a battery change, make sure to reset any mis-aligned chronograph hands to “0”.
Keep buttons and crown clean; ensure the watch is not running the stopwatch before setting the time.
For optimal accuracy: battery life is approx. ~2 to 3 years; maintain service as needed.
Avoid strong chemicals & solvents
Clean with a soft microfiber cloth
Keep away from magnets
