Hand-wound, barrel-shaped movement with tourbillon escapement. Hallmark of Geneva Certified.
This tonneau-shaped movement perfectly tailored to the case is entirely developed and crafted within the Manufacture. The tourbillon carriage, inspired by the brand’s signature Maltese cross emblem, provides a splendid showcase for the exceptional level of finishing of each movement part, including a number of naturally hand-bevelled interior angles. Rounding off the tourbillon bar alone called for 12 hours of hand craftsmanship in order to meet the finishing criteria established by Vacheron Constantin. This technique, referred to in French as berçage, consists of filing the tips of the arms with perfect regularity so as to give them a conical and semi-cylindrical shape, while respecting the limits of the centre and the heels. To finalise the operation, the artisans smooth it down using stones, buffs, wooden pegs and special pastes in order to achieve a perfectly polished effect.
