Overseas Ultra-Thin Perpetual Calendar Skeleton White Gold 41mm

About the Model

The Vacheron Constantin Overseas Ultra-Thin Perpetual Calendar Skeleton (ref. 4300V/120G-B946) brings openworked complexity to one of the maison’s most refined modern sports lines. Introduced in 2021, it distinguishes itself through a fully skeletonized execution of both the dial and movement – revealing the architecture beneath one of watchmaking’s most lauded calendar mechanisms.

Crafted in 41.5mm white gold, the case continues the Overseas tradition of sharp edges and integrated styling, here matched by an interchangeable system offering a bracelet, rubber strap, and alligator option. Inside, the ultra-thin automatic calibre 1120 QP SQ delivers perpetual calendar functionality – day, date, month, and moonphase – through a movement just 4.05mm thick. Despite its delicacy, it supplies a 40-hour power reserve and operates at 2.75Hz, with every bridge, wheel, and rotor visible through both the open dial and exhibition caseback.

With its sapphire-intense transparency and architectural movement finishing, ref. 4300V/120G-B946 is among the most technically and visually arresting interpretations of the Overseas – a reference that bridges classic complications and cutting-edge design in the thinnest possible profile.Read MoreThe Skeleton Navigator
