About the Vacheron Constantin 4300V/220G-H151
The Vacheron Constantin Overseas Perpetual Calendar Ultra-Thin 4300V/220G-H151 debuted in 2025. The 18k white gold case measures 41.5mm in diameter and 8.1mm in thickness. It incorporates a soft iron casing ring for magnetic protection, sapphire crystals front and back, and is rated water resistant to 50 meters.
The dial is finished in burgundy lacquer with a sunburst satin base, velvet-finished flange, and snailed sub-counters. The moon phase disc and moons are executed in white gold, echoing the case. White gold applied indexes and hands, coated with blue Super-LumiNova, complete the display.
Inside is the self-winding caliber 1120 QP/1. This movement measures 29.6mm across and 4.05mm thick, and is composed of 276 parts with 36 jewels. It runs at 19,800 vph and provides a power reserve of 40 hours. Functions include hours, minutes, perpetual calendar with day, date, month and leap year, and moon phase. The 22k gold rotor visible through the case back is engraved with a compass rose.
Delivered on a white gold bracelet with Maltese cross-shaped links and folding clasp, this reference also includes two interchangeable rubber straps in burgundy and white with matching white gold buckle. The watch carries the Geneva Seal.
