The Vacheron Constantin Overseas Ultra-Thin Perpetual Calendar ref. 4300V was first released in 2018 and this year ref. 4300V/000R-B5094 was added. This reference sporting a gorgeous blue dial brings this watch another notch up. The watch is fitted with a slender case in 18K 5N pink gold measuring just 8.1 mm in thickness and powered by a new calibre 1120 QP/1. This new Overseas Ultra-Thin Perpetual Calendar is simply stunning in the metal and is powered by one of the slimmest movements on the market.

Its 18K 5N pink gold case, measuring 41.5 mm in diameter and water-resistant to 50 meters, frames a dark blue lacquered dial punctuated by 18K gold hands and hour markers highlighted with luminescent material.

Fitted with a sapphire crystal case back, the movement is fully visible with its 22K oscillating weight adorned with a wind rose. An authentic feat of miniaturization, this barely 4.05 mm thick movement comprising 276 parts keeps track of calendar irregularities with no need for correction until 2100. Beating at a frequency of 19,800 vph and endowed with an approximately 40-hour power reserve, it drives the hours and minutes, perpetual calendar —day of the week, date, month and leap year on a 48-month counter— as well as moon-phase functions.

Secured by an interchangeable 18K 5N pink gold folding clasp, the equally interchangeable dark blue alligator or rubber straps provide a chic way of accentuating the refinement of this model. On the wrist, the new Overseas Ultra-Thin Perpetual Calendar ref. 4300V wears true to its size and impeccably.
