1.3. Setting the date and hour hands:
Pull the crown out to position 2. Then turn the crown: the hand
moves in 1-hour jumps. If it is necessary to correct the date (A),
continue to turn the crown and the date will change automati-
cally when switching from AM to PM, or the contrary, depending
on the direction the crown is turned. Then push the crown back
to position 1.
Important: when setting the date, it is essential to check the
date. If need be, pass midday (no date change) or midnight (date
changes) to make sure the time is set in AM or PM as appropriate.
Note: corrections in position 3 have no effect on the date, even
if the hour hand passes midday or midnight. The watch stores
the date in its memory (including whether AM or PM) before the
time is reset. Setting the hours, minutes and seconds, around mid-
night and midday may therefore result in the calendar shifting by
12 hours.
2. Checking and correcting the calendar: month, yearly
cycle and date.
2.1. Display and correction of the month.
Press and hold the crown in position 0 for more than 3 seconds,
the month will be displayed for 8 seconds (B). 1 = January, 2 =
February, ..., 12 = December. The month can be corrected during
these 8 seconds. Pull the crown out to position 2, turn the hour
hand through one full revolution. The month will move forwards
or backwards.
Repeat the procedure until the required month is displayed, then
put the crown back to position 1.

2.2. Display and correction of the yearly cycle.
Following display of the month (cf. 2.1.), the calendar continues
to function and the year cycle is displayed in Roman numerals for
8 seconds (C).
I = leap year +1 example: 2005, 2009, 2013
II = leap year +2 example: 2006, 2010, 2014
III = leap year +3 example: 2007, 2011, 2015
IV = leap year example: 2004, 2008, 2012
During these eight seconds, you can adjust the year cycle. To
do so, pull the crown out to position 2, turn the hour hand through
one full revolution. The year cycle will move forwards or back-
wards.
Repeat the procedure until the required yearly cycle is displayed.
Push the crown back to position 1.
The calendar continues to function and displays the date (A).
See point 1.3. for how to correct the date.
2.3. Changing the time zone or daylight saving time:
Pull the crown out to position 2 and turn it. Only the hour hand
will move forwards or backwards, without affecting the minutes
or seconds. Push the crown back to position 1.
Note: the end of battery life is indicated by the seconds hand
making 4-second jumps. The watch will continue to function for several
days, but the battery must be removed and replaced by an authorised
OMEGA service agent as soon as possible.
Once the watch stops, a memory function stores the date for one
month.
