Adjusting the functions
Adjusting the moon phase
The moon disc can be adjusted using the corrector at 10 o'clock. Applying pressure with the corrector
stylus will move the moon disc forwards by one day. You will find a calendar indicating the dates of the full
moons for forthcoming years hereinafter.
To correctly adjust the moon phase, count the number of days that have passed since the last full moon.
Next, adjust your watch so that it displays the full moon (the moon-cover must be completely invisible) and
then push on the corrector using the stylus the same number of times as the number of days that have
elapsed since the last full moon. Once adjusted, your moon disc will be mechanically driven.
Usage precautions
The moon phase must not be adjusted between 10 p.m. and 1 a.m. under any circumstances, as it is
during this period that the movement automatically changes the moon phase displayed. Any adjustments
made during this period will not be taken into account by the movement.
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.
