Adjusting the fonctions
Winding the mouvement
Proceed to wind the movement with the crown in position 0. Turn it forward until it locks.
Setting the time
Pull the crown out to position 1, then turn it forward or backward to position the hands.
Push the crown back to position 0 after the adjustment.
Setting the moon phase
Use the corrector at 9 o'clock to set the moon disc. With the correction tool, press once to advance the
moon disc by one day. You will find a calendar indicating the dates of the full moons for forthcoming
years hereinafter.
To make a correct setting, press on the corrector successively until the disc is on full moon position.
Calculate the number of days that have elapsed since the last full moon, using the calendar at the end of
this manual. Press on the corrector as many times as the number of days elapsed. Once you have set your
moon disc, it will be mechanically driven. You can make a correction at any time, because the moon-phase
mechanism is protected and will not be damaged by ill-timed correction operations.

It is essential to manipulate the correctors using the appropriate tool delivered
in the case, to take your time and to ensure that they have been pushed in fully
before proceeding with any other adjustments.
