Calibre J800.1 / J820.2
Important note:
Do not make any changes to the date between 08:00 p.m. and 02:00
a.m., as the date is automatically advanced by the movement during
this period and you could damage the date advance mechanism.
Winding up the watch
With the winder in position A, you can wind up the automatic move-
ment manually. At least 2 to 3 rotations of the winder are needed to
start the movement. It is better to wind it up completely. It is fully
wound up after c. 40 rotations of the winder, as then the maximum
accuracy and its power reserve (even after the watch is put down) will
last for the maximum period.If your model has a screw-locked winder,
this must be un screwed by turning it to the left to start your watch
going. After you have set your watch, you should wear it, so that the
automatic winding system (via rotor movement) keeps it constantly
operational.
