Moon phase correction
Crown in position II, intermediate
Pull the crown out to position II and turn it clockwise
to correct the moon position, referring to a lunar
phase chart. Push the crown back into the rest
position I. During this operation, your watch will con-
tinue running, so the time will not need to be re-set.
Important: Moon phase correction is impossi-
ble between 3 a.m. and 4 a.m.
Day correction
Press the corrector as many time as needed (15), to
move the disc forward until the desired day is dis-
played in the aperture (6). During this operation, your
watch will continue running, so the time will not need
to be re-set.
Important: Day correction is impossible
between 9.30 p.m. and midnight.
