The chronograph runs for 12 hours.

It will display elapsed time up to a maximum of 11 hours 59’ 59”.

Because it has no automatic stop mechanism, it will continue measurement until you stop it. Once the time measured exceeds 12 hours, the chronograph reverts to 1 second and continues measuring.

Once you have started the chronograph, you must stop it or it will rapidly run down the battery.

The time is displayed normally while the chronograph is in use.
