TOURBILLON WITH THREE GOLD BRIDGES, 40 MM

TOURBILLON WITH THREE GOLD BRIDGES AUTOMATIC WINDING

To create an automatic version of the Tourbillon with Three Gold Bridges, the master
watchmakers were asked to respect both the dimension of the movement and
the perfect architecture of the three gold Bridges.

Their idea, a stroke of inspiration, was to use the free space on the plate below
and around the barrel to install a small gold rotor which, due to its high density, would compensate
for its small diameter.

This technical feat resulted in an absolutely reliable movement, with a power reserve
of 50 hours, in a watch that is recognized throughout the world as one of
the most beautiful Tourbillon ever produced by Switzerland’s master watchmakers.
