The Model 1 Triple-Four
Movement and Rotor
Your Triple-Four watch
has an exhibition back
to show the highly
finished movement and
bespoke rotor. The rotor
is a semi-circular weight
that is mounted on the
movement. It is also
known as an oscillating
weight. The rotor rotates
in either direction due
to the movement of
the watch on the wrist.
Through a series of
gears, the movement
of the rotor winds the
mainspring, which
supplies the watch with
mechanical energy.
