You are not sure how to adjust your Chrono correctly or you lost your manual?
No problem, you can download the manual here.
Since our Chrono is a bit more special and has a few more buttons, you can also find a small video here, which hopefully makes the initial settings easier:
Why is the seconds dial of my chrono not at the 12 o'clock position?
The crown must be pulled out as far as possible. Then press both buttons above and below the crown equally until the second dial rotates about 360°. Then press the button above the crown until the second dial is at the 12 o'clock position or any other desired position. Finally, you simply push the crown back in. Now the seconds dial should be where you want it to be.
