A Perpetual Calendar in a Sports Watch
A perpetual calendar knows the length of every month and adjusts for leap years automatically. Once set, it shows the correct date until the year 2100 without manual correction. Vacheron Constantin first placed this complication in the Overseas in pink gold. In 2021 the brand added two white gold versions: the 4300V/120G-B945 with a blue lacquered dial and this skeletonised 4300V/120G-B946.
Design: Blue Rings Over an Open Movement
Skeletonising a perpetual calendar is one of the hardest jobs in watchmaking, because every bridge and plate must be cut away and hand-finished without weakening the mechanism. The 4300V/120G-B946 shows its calendar on blue rings set over the open movement: month at 12 o'clock, day at 9, date at 3 and moon phase at 6. White gold hands and applied markers carry luminescent material, and the polished hexagonal bezel references the Maltese cross.
The 8.1mm case slips under a cuff like a dress watch, while the brushed white gold bracelet and the tool-free strap system give it everyday sports-watch versatility.
Movement: Calibre 1120 QPSQ/1
The ultra-thin in-house Calibre 1120 QPSQ/1 measures only 4.05mm thick. It has 276 components and 36 jewels, runs at 2.75 Hz and provides 40 hours of power reserve. It is certified with the Hallmark of Geneva, and its openworked oscillating weight is shaped like the Maltese cross.

- A skeletonised perpetual calendar, one of the most complex combinations in haute horlogerie
