The Vacheron Constantin Overseas Tourbillon Skeleton watch features architecture and finishes that are meticulous in every detail, reflecting the quest for excellence cherished by the Maison. This model is the first Overseas timepiece equipped with a tourbillon movement in a skeletonised version.
The skeletonisation work carried out on self-winding Calibre 2160 has enabled not only a 20% reduction in the movement's weight but also a complete rethink of its architecture. Its curvature is thus very slender, at barely 5.65 mm thick – a real technical feat considering the requirements linked to the integration of a tourbillon carriage.
This thinness is notably due to the choice of a peripheral gold oscillating weight, which also enables a completely clear view of the rear of the movement. The work done on the baseplate and the four bridges can be clearly admired, with the NAC surface treatment applied by electrolysis conferring an anthracite grey tint.
