Chronometer testing (model-dependent)
Depending on model, your watch is subjected to chronometer testing,
guaranteeing you the highest precision and reliability as a conse-
quence. The strict criteria of the chronometer test stipulate a 15-day
inspection. In the five positions "crown left", "crown above", "crown
below", "dial above" and "dial below" the mean daily rating must lie
between – 4 and + 6 seconds, whereby the mean daily rating deviation
must not exceed two seconds and the maximum rating deviation five
seconds. All watches are tested at several different temperatures and
an air humidity level of approximately 50 %. In each case the devia-
tion is measured after 24 hours.
The test is documented in the form of a chronometer certificate.

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. 43 rotations of the winder, as then the maximum
accuracy and its power reserve (even after the watch is put down) wil
last for the maximum period. After you have set your watch, you should
wear it, so that the automatic winding system (via rotor movement)
keeps it constantly operational.
