CALIBRE 1866–Date and moon phase correction
Date setting (small counter at 12 o'clock): press
corrector C.
Setting the moon phase: press corrector D to move the
disc into the full-moon position. Then determine how
many days have elapsed since the last full moon (consult
a calendar) and press the corrector the equivalent number
of times.
When the watch is running, the date and moon phase
move forward automatically.
Important:
Avoid pressing correctors C and D (date and moon phase) if
the watch is displaying any time between 7 and 12 o'clock
(am or pm).
Do not set the date by moving the hour hand past midnight,
since this may desynchronise the date and moon phase indi-
cators.
