Logical One

Romain Gauthier’s signature watch and the piece that won the 2013 GPHG Men’s Complication prize: a chain-and-fusée constant-force mechanism, not a tourbillon, with the fusée replaced by a rotating snail cam so the ruby-link chain stays on one plane. Grand feu enamel dials are made in-house. The Final Edition (2021–2023, titanium or 18k white gold, 20 pieces per material) closed the line.

Year introduced: 20131 reference
