C by Romain Gauthier calibre

Finger bridges - history of the Vallée de Joux
Inspired by the finger bridges style, the design of the movement follows the watchmaking history of the Vallée de Joux, with a modern approach, reflecting Romain’s vision of the evolution of tradition.

Hand-engraved bridges and bevelling
The outer edges of each bridge all feature a double bevel, while the flat bridge surfaces and rubies are each framed by a raised border that has been straight-grained. Within these borders, the hand-finishing specialists at Manufacture Romain Gauthier have used a special hand-engraving technique to create a highly original dimpled texture.

Snail cam
Like many stop-seconds mechanisms, a brake is placed on C by Romain Gauthier’s balance wheel when the crown is pulled out. But instead of using a straight or L-shaped balance stop lever to halt the balance, Romain has opted to employ a snail cam that performs a double function: It touches and stops the balance wheel when the crown is pulled out and, when the crown is pushed back in, the snail cam makes a turn, with its increasingly wide form giving the balance an impulse to help it start beating again.

Gears and ratchet wheels with circular, bevelled spokes
The distinctive gears and ratchet wheels feature circular spokes providing elegance and strength.
These spokes also bear eye-catching bevels, rarely seen in high-end watchmaking.

Bespoke balance wheel and triangular pallet lever
The regulator features the Romain Gauthier balance wheel with curved arms and calibrated eccentric weights, plus hand-assembled pallet lever that is triangular for maximum rigidity.

S-slot screw heads
The signature screw heads bear an S-slot that not only is aesthetic, but also enables more torque to be applied during movement assembly.
