2.0 Disassembling the chronograph module
The chronograph is always disassembled in the START
position.
The chronograph module must be completely disas-
sembled. All parts should be cleaned carefully. We do,
however, advise you to keep the parts below assembled
during cleaning.
Components which must not be disassembled during cleaning
Do not turn the eccentric screw needlessly! The dial screws must be tightened well
before cleaning to avoid losing them.

3.5 Check the uncoupling spring position:
4.0 Inspection + Adjusting the hammer
There is no need to adjust the hammer if the chrono-
graph wheel bridge eccentric (ref. 10.047) has not been
loosened during the service, as the movement is factory-
adjusted.
You can nevertheless check as follows :
1. Fit the chronograph hands (without the dial).
2. Carry out a START-STOP and then reset to zero.
3. Check that the hands are free using a wooden pin:
a. the chrono second hand + minute counter must not
move when the reset is held down;
b. there must be a slight freedom play of the hour coun-
ter (~1° to 5°).
If OK : check finished, move to point 9.
If not OK : move to point 4.
4. Loosen the eccentric screw.

5. Whilst holding the reset down, turn the eccentric until the
chronograph hand can be blocked (under tension). Then
tighten the eccentric screw.
6. Check the freedom of the hour counter (~1°to 5°). If not
OK, start again at point 4.
7. Check that the minute counter is blocked
If OK (no play): move to point 9.
If not OK (free): move the hammer pean aside gently
using a screwdriver. This adjustement takes place in the
START position.
Reset and check that there is no freedom in the minute
counter.
8. Carry out a START-STOP and then reset to zero. Then
check again from point 3.
9. Oil the eccentric pivoting lightly and oil the module
according to the drawing on page 16.
