Self-winding chronograph

Operating instructions2

This indicator operates simulta-

neously with the chronograph

hands. Each circle on the display

corresponds to 1 minute.

For a regatta, the chronograph

should be started at the warning

signal by pressing pusher A.

If the 5 circles on the display have changed colour to blue, this means

that 5 minutes have elapsed 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.

NB: if the chronograph function is stopped, the regatta function

also stops, since the two functions are synchronised.

Apnea function (calibre 3601)

In addition to the hours and minutes

hands, this movement has an indica-

tor that displays the elapsed time

of a dive. This indicator operates

simultaneously with the chrono-

graph 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.

Note: the calibre 3601 has no hours or minutes counter or small-

seconds hand.

The crown has 3 positions:

Watch functions:

1. Normal position (wearing position): when the crown is posi-

tioned against the case, the crown ensures that the watch is water-

resistant.

Occasional winding: if the watch has not been worn for 44 hours

or more (calibres 3888, 3890: 52 hours), wind it up with the crown

in position 1.

2. Correcting the date: pull the crown out to position 2, turn the

crown forwards (backwards for calibres 1151, 3606), then push the

crown back to position 1.

NB: the date cannot be corrected between 8:30pm and 1am. (9pm

and 4am for the calibres 1151 and 3606; see note below for the

calibres 3888 and 3890).
