Vacheron Constantin introduced the Overseas Perpetual Calendar Ultra-Thin in two new executions in 2025, in pink gold (4300V/220R-H144) and white gold (4300V/220G-H151), both within the sporty Overseas line the Geneva manufacture launched as a daily-wear alternative to its more classical complications. The reference pairs the perpetual calendar complication with an ultra-thin construction, a field where Vacheron Constantin holds a recognized pedigree in high horology.
At the heart of the watch is Calibre 1120 QP/1, an in-house automatic movement that adds a perpetual calendar module to the historic base Calibre 1120, one of the oldest ultra-thin automatics still in production in Swiss watchmaking. At just 4.05mm thick and 29.6mm in diameter, the movement houses 36 jewels and a 22kt gold central rotor, beats at 2.75Hz, and delivers a 40-hour power reserve. The perpetual calendar indicates day, date, month, leap year, and moon phase, requiring no manual correction until the year 2100.
The 18kt pink gold case measures 41.5mm in diameter and just 8.1mm thick, with a sapphire case back exposing the movement and a soft-iron inner case shielding it from magnetic fields. The dial echoes the pink gold tone with a sunray finish, with tone-on-tone sub-registers for the calendar and moon-phase displays.
The bracelet, also in 18kt pink gold, uses the quick-release system that has defined the Overseas line since its 2016 redesign, letting the wearer swap between the metal bracelet and two rubber straps included as standard, without tools. Every example carries the Hallmark of Geneva, the quality certification that requires Vacheron Constantin to manufacture and finish the movement within the canton of Geneva to a specific set of criteria.
At its 2025 launch, Vacheron Constantin priced this reference at EUR 134,000 including tax; that figure is a historical launch price, not a current market valuation. As of this writing, the 4300V/220R-H144 remains in the manufacture's current catalog.
Cazador has no verified market price observations for this reference. At its 2025 launch, Vacheron Constantin priced it at EUR 134,000 including tax, but that is a historical figure, not a current market read.
They share the movement and case dimensions; the 4300V/220R-H144 is pink gold with a tone-on-tone pink gold dial, while the 4300V/220G-H151 is white gold with a burgundy dial.

It's Geneva's quality certification, requiring the movement to be manufactured and finished within the canton of Geneva to specific technical and aesthetic criteria, beyond precision standards alone.
