Self-winding chronograph

Regatta function (continued)

For a yacht race, the chronograph should be started at the warning signal by pressing pusher A. Once the 5 circles on the display have changed colour to blue, this means that 5 minutes have passed since the warning signal. Once the circles have changed to red, this means that 10 minutes have elapsed and that the starting line can be crossed.

NOTE: If the chronograph function is stopped, the regatta function also stops, since the two functions are synchro- nised.

Apnea function (cal. 3601)

Pusher A: start – stop, start – stop etc. Timing to 1/8th of a second.

Pusher B: reset (after a stop).

Apnea function based on a 14 minute dive:

In addition to the hours and minutes hands, this movement has an indi- cator that displays the elapsed time of a dive. This indicator operates simultaneously with the chronograph seconds hand. Each circle on the display corresponds to 1 minute.

Before a dive, the chronograph should be started. Once the 7 circles on the display have changed to red, this means that 7 minutes have elapsed. Once the red colour has disappeared from the 7 circles this means that 7 more minutes have elapsed.
