Quartz chronograph
Operating instructions
2
The chronograph functions are provided by a combination of quartz
and mechanical technology. The chronograph hand, driven by a
separate motor, makes 16 jumps per second. Its movement appears
continuous and it can be read off the scale to within 1/10th of a
second. The reset function, like the minute and hour totaliser func-
tions, is carried out mechanically. The return to zero is instanta-
neous.
In order to reduce energy consumption to a minimum, the chrono-
graph automatically stops after more than 11 hours of operation.
The crown has 3 positions:
