A C Edition Six, 1 of 88 examples of the final installment of the C by Romain Gauthier. Featuring a partially openworked sapphire dial, the Edition Six pairs a more technical aesthetic with a rubber strap and orange accents. This design exposes the escapement line assembly and seconds wheel, with an extra bridge on the lower half still featuring the hand-engraved boucharder texture. The C Edition Six weighs an extremely light 55 grams thanks to their lightest case configuration yet and an entirely titanium in-house calibre.
