IMPORTANT
To be observed strictly
The watch must in no case be demagnetized.
In order not to disturb the proper functioning of
the watch the electronic module (fig. 1.1) must not
be touched with the fingers.
The new power cell should be manipulated by
means of tweezers with insulated tips (fig. 2.1).

REPLACEMENT OF POWER CELL
1.1. Open the case.
1.2. Remove and clean the back.
1.3. Remove magnetic protection.
1.4. Remove power cell bridle No. 1310.9179 by
unscrewing its screw.
1.5. Remove by suction any possible metal waste
caused by the screw of the power cell bridle.
1.6. Remove faulty power cell by turning the
watch over.
1.7. Check cleanliness of the two power cell

bridle No 1310.9179.
the lower power cell contact (negative pole): to
clean carefully the bridle by means of a buff.
1.8. Check new power cell. Even if minute
leakages are apparent, it should not be used. Place
power cell No 9903 in position, positive pole (+)
uppermost (fig. 3.1).
1.9. Refit power cell bridle and screw thoroughly.
1.10. Fit magnetic protection.
1.11. Grease water-resistance gasket. Close the
case.
COMPONENTS

Folder 2 - Adjustment of the rate
Electronic module fig. 1.2
IMPORTANT
To be observed strictly
The watch must in no case be demagnetized.
In order not to disturb the proper functioning of
the watch, the electronic module (fig. 1.2) must
not be touched either with a tool - except key for
trimmer - or with the fingers.

ADJUSTMENT OF THE RATE
2.1. Open the case.
2.2. Remove and clean the back.
2.3. Place watch on captor, movement side
uppermost, and press button "l Hz" of
DELTATEST.
Note
Generally, a measuring time of 10 seconds and
a measuring accuracy of 1/100th second will be
used.
2.4. Read instant rate shown on DELTATEST.
Note
Adjustment can only be effected if the daily rate
is lower than the possibilities offered by the
trimmer.
The guide-mark printed on the trimmer should
not be moved outside the limits indicated by fig.
2.2. The total correction area allows a rate
adjustment of 10 seconds.
If the daily rate is higher than the possible
correction limits, the electronic module should
be replaced (see folder 3-1310).
Fig. 2.2

Cal. 1310 5
2.5. Where correction of the daily rate is possible,
adjust said rate by means of trimmer, using the key
specially devised for this purpose (fig. 3.2). This key
only must be used in order not to damage the
trimmer. Excess pressure should be avoided during
this operation.
By moving the guide-mark of the trimmer in a
clockwise direction, a gain is obtained; by moving it
in the opposite direction, a loss.
Adjust the watch in relation to the ambient
temperature, according to fig. 4.2.
In order that the temperature of the watch may be
equal to the ambient temperature, it is necessary to
wait about one hour before the measuring is effected.
The values indicated in fig. 4.2. are valid for
a watch with closed back.
Turn the trimmer, bearing in mind a gain of 0.10 to
0.20 sec. as compared with the desired adjustment
according to fig. 4.2, in order to compensate the loss
caused by closing of the case.
2.6. Grease the water-resistance gasket. Close the
case.
2.7. Set the watch and check frequency on
DELTATEST after 24 hours.

compensate the backlash before fitting the
second hand. This latter hand will be fitted
on an even number index.
3.10. Checking of the second hand jump; this
latter hand being positioned on an even
number, push the hand-setting stem; 1
second after this function the hand should
make its first jump. If this is not so, take off
the second hand and move it by 1 second
before refitting.
3.11. Proceed with casing-up of movement.
3.12. Set up feed by substitute power cell and
check by means of Alitest that the watch
functions between 1.15 V and 1.40 V.
3.13. Measure current. Consumption should
not exceed 15 µA under a tension of 1.35 V.
Should one of the conditions mentioned not
apply, then the movement must be returned
to the Omega agent.
3.14. Place power cell in position (see folder
1-1310).
3.15. Fit magnetic protection.
3.16. Proceed with adjustment of the rate

3.30.
Unscrew the 2 motor connecting screws (2),
motor module screw No. 2377 (8)
and motor eccentric locking screw No. 2582
(9).
3.31.
Extract faulty motor module No. 1310.9200.
3.32.
Place new motor module in position.
3.33.
Important : Screw very slightly the 2 motor
connecting screws (2) and motor module
screw (8).
3.34.
Fit simultaneously the third and second
wheels.
3.35.
Fit wheel train bridge and tighten its screw.
3.36.
Adjustment of motor-second wheel backlash
by motor eccentric No. 1310.9227. Turn
motor eccentric clockwise until wheel train is
stopped, using the tool specially devised for
this purpose (fig. 3.3.). If locking of the motor
is impossible, the eccentric should be left in
its position of maximum eccentricity (fig. 3.3
(B). The following operation 3.37 will not be
necessary.
3.37.
Turn eccentric slowly in the opposite
direction until the wheel train
turns normally, i.e. always in the same
direction (the wheel train is free, without
backlash).
Important : Check rotation of wheel train
curing one minute at least.
3.38.
The backlash between motor and second
wheel is then obtained by turning the motor
eccentric through an angle of 40°. To secure
this angle accurately, place tool on eccentric,
hold with one hand the upper part of the
instrument, and with the other hand turn
handle arrow-wise (fig. 3.3.) as far as tool
banking.
For the movements which have not been
stopped by operation 3.36, check that the
wheeltrain is always turning in the same
direction, then effect the 40° recoil.
Fig. 3.3
wheel-train bridge direction
Fig. 3.3. (B)
Important : If a faulty operation has occurred
in adjusting the backlash, it will be necessary
to recommence the entire adjustment as from
operation 3.36, and to follow the indications
scrupulously.
3.39.
Tighten the motor eccentric locking-screw.
3.40.
Lock motor module screw and the 2 motor
connecting screws.
3.41.
Adjustment of click by microscope : This
operation is carried out in "stop second"
position of the hand setting stem. Before
adjustment, turn the hand setting stem arrow-
wise in order to compensate the backlash.

3.42. Slightly unscrew the screw No. 2564
(point 11, fig. 4.3.) for retaining click plate.
3.43. Engage click (6) on retaining wheel
(12). The tip of the blade must be at the top
of a tooth, as close as possible, without
touching it (position a, fig. 5.3.). If necessary,
move retaining click plate No. 1310.9026
(13) by turning the eccentric of click bearing
plate No. 1310.9029 (14).
3.44. Lock screw of retaining click plate.
Check again the click position after having
turned the stem according to fig. 5.3.
3.45. Start the watch by pushing hand setting
stem. Engage click in retaining wheel by
turning the click stud until the blade touches
the tooth (c). Turn slightly further the click
stud in order to tighten the blade (position b),
and so that a space (d) appears between the
end of the click and the tooth (e).
Important : The distance (d) between the
end of the blade and the tooth (e) must be as
small as possible. It is necessary to check
during one minute at least the passage of the
60 teeth of the retaining wheel. The click
must never touch the tooth at point (e).
3.46. Fit second hand according
to op. 3.9. and 3.10.
3.47. Follow operation in the order 3.11 to
3.16.
