MAIN FEATURES
(MANY OF WHICH ARE MAJOR TECHNICAL INNOVATIONS)
POWER RESERVE
Circa 70 hours, located on a scale at 2 o’clock.
FUNCTION INDICATOR
In a manner similar to a car's gearbox, the function
indicator allows one to see the winding, neutral and hand setting positions as
the crown is pulled out. Each position is indicated via a hand at 4 o’clock
displaying the following functions: W (Winding) – N (Neutral) – H (Hands).

VARIABLE INERTIA, FREE SPRUNG BALANCE
The free-sprung balance provides better reliability in the
event of shocks, movement assembly and disassembly. It also guarantees better
chronometric results over an extended period of time.

TORQUE LIMITING CROWN IN TITANIUM
This additional security system prevents from accidental
overwinding, which could cause damage such as the winding stem breaking or too
much pressure on the barrel spring.

FAST ROTATING BARREL (6 hours per revolution instead of 7,5)
This type of barrel provides the following advantages:
The phenomenon of periodic internal mainspring adhesion is
significantly diminished, thereby increasing performance,

BARREL PAWL WITH PROGRESSIVE RECOIL
This device permits an appreciable winding gain (circa 20%),
especially during the start of winding.

WINDING BARREL TEETH AND THIRD-WHEEL PINION WITH CENTRAL
INVOLUTE PROFILE
INVOLUTE PROFILE
The central involute profile of the winding barrel teeth and
pinion provides an optimal pressure angle of 20°. This promotes effective
rotary motion and allows for compensation of possible variations in the
engagement of the going train, thus insuring excellent torque transmission with
a distinct improvement in performance.

SAFETY SYSTEM WITH BLOCKING GEAR
This system protects the roller jewel of the balance as well
as the winding barrel from possible overwinding.
