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.
TACHYMETRIC SCALES
The desired information is read between the central seconds hand of the
chronograph and the corresponding scale, over a maximum duration of 60
seconds.
Example: calculating the speed of a car.
Record the time the car takes to cover a distance of 1 kilometre. Read off the
tachymetric scale the speed indicated by the central seconds hand. In this case,
the car is travelling at 120 km/h.
FOLDOVER CLASPS
Opening (fig. 1):
to open the clasp, press the two pushers on either side of the
OMEGA buckle and pull upwards.
Closing (fig. 2):
put the watch on your wrist and close the clasp by pushing on it
with your thumb until you hear a click. (fig. 2).
Adjusting the length (fig. 3):
free the longer section from the two slideways
(A) and from the catch (B). Adjust the bracelet in the required direction and
reinsert in the catch and the two slideways. Try the watch for size and readjust if
necessary.
