•  Pusher B: reset (after a stop).
Note: resetting/zeroing of the sub dials must only be carried out after 
the chronograph has stopped. Never push the chronograph’s two 
 
pushers (A and B) simultaneously (calibre 3201).
Calibre 1866 – date and moon phase correction
–  Correcting the date (small counter at 12 o’clock): press 
 
corrector (C).
–  Correcting 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 indicators.
