Hours
The hour wheel arbor is carried by the barrel-drum. The wheel rolls in
the fixed rack and drives the center-pinion. An arrow applied on the bar-
rel indicates the hour. The barrel contains the mainspring and makes
one complete rotation in a 12 hour period.
Minutes
The carrousel tourbillon movement is assembled onto the center-pin-
ion. Its first wheel rolls on the fixed rack and gathers the necessary
power to maintain the oscillation of the balance. The baguette move-
ment rotates once in 60 minutes, and so serves as the minute hand.
Setting the Freak Vision
A lock situated at 6 o'clock between the horns of the case permits
releasing and locking of the bezel. The bezel can be turned in either
direction. Upon correctly setting the time, push the guard back into
position. This will lock the bezel, preventing involuntary changes of the
time.
Manual winding
Turning the case-back counter-clockwise winds the main spring.
