Embodying generations of horological mastery, the Vacheron Constantin Overseas Perpetual Calendar Ultra-Thin Skeleton Ref. 4300V/220R-B642 is a masterpiece of technical precision and refined aesthetics.

• Pink Gold Case: The 41.5mm 18k pink gold case houses an exceptionally slim perpetual calendar movement, measuring just 8.1mm thick. A transparent sapphire crystal caseback provides a view of the beautifully decorated, anthracite-gray NAC-coated caliber and its openworked 22K gold oscillating weight.

• Automatic Movement: At its heart is the in-house Calibre 1120 QPSQ, an ultra-thin self-winding perpetual calendar movement with a 40-hour power reserve. The mechanism is certified with the prestigious Hallmark of Geneva, a testament to its exceptional craftsmanship..

• Perpetual Calendar: The watch features a perpetual calendar with a 48-month leap year counter, along with indications for the day, date, and month, which will not require adjustment until 2100.

• Moon Phase: A star-studded sky and two gold moons adorn the moon phase display, adding a celestial touch to the watch's intricate design.

• Interchangeable Bracelet/Strap System: The watch comes with a three-strap system, allowing for quick and tool-free changes between the 18K pink gold bracelet, a dark blue calfksin leather strap, and a dark blue rubber strap.

• Authorized Vacheron Constantin Boutique: Guaranteed authentic, backed by the Vacheron Constantin 2-year warranty.
