Vacheron Constantin is revisiting one of its most iconic models in their collections, we are talking about the new Traditionnelle Chronograph Perpetual Calendar ref. 5000T/000P-B048. Equipped with the new Manufacture Vacheron Constantin Calibre 1142 QP, this timepiece perpetuates the tradition of excellence cultivated by the finest Geneva watchmakers. With this new creation appearing in a 43 mm case in 950 platinum, Vacheron Constantin has opted to combine two key Fine Watchmaking complications: the chronograph and the perpetual calendar. With its classic round case, the Traditionnelle collection by Vacheron Constantin embodies the values cherished by the Maison, combining tradition and formal elegance with supreme mastery of horological complications.

The new Traditionnelle chronograph perpetual calendar is the ultimate expression of this successful synergy. The collection’s distinctive design codes are reflected in each and every detail: the stepped case with a distinctive fluted pattern on the back, the dauphine-style hands and the railway-type minute track. A white tachymeter scale surrounding the dial accentuates the technical nature of the watch.Exemplifying a concern for legibility, the dial features various shades of grey with finishes that differ according to the functions, reflecting the layout of 1940s Vacheron Constantin chronographs. Standing out against a slate-colored opaline base, the small seconds and chronograph minute counters are distinguished by a circular-brushed ring with snailed center. The 22K white gold moon disc is hand-finished in keeping with the fine tradition of artistic crafts cultivated by Vacheron Constantin. Positioned in the center of the date counter with a dark grey rim, it provides a symbolic depiction of a moon face that is alternately smiling or melancholy, depending on the path of the Earth’s satellite. A subtle nod to historical pocket watches. Subtle evolution This sophisticated aesthetic approach is matched by the technical evolution embodied in the movement of the Traditionnelle Chronograph Perpetual Calendar.

Powered by the new in-house calibre 1142 QP with 324 parts and 21 jewels, this state-of-the-art manual wound movement entirely designed and developed within the Manufacture, this movement replaces the previous 1141 QP. The new movement drives the perpetual calendar functions – with indications of the date, days, months, leap years and moon phases – as well as the chronograph functions with a direct-drive seconds hands and 30-minute counter at 3 o’clock, positioned opposite the small seconds at 9 o’clock. This newcomer to the Traditionnelle collection will thus be able to keep track of all the vagaries of the calendar without any need for adjustments until March 1st 2100. High standards certified by the Hallmark of Geneva with the development of this new caliber, the Vacheron Constantin watchmakers and developers have been keenly attentive to the energy constraints relating to the chronograph functions, in order to minimize their impact on the 48-hour power reserve. The oscillation frequency of the balance has also been raised from 2.5 to 3 Hz —21,600 vph— so as to increase reliability and shock resistance. Like all Vacheron Constantin movements, this new calibre visible through an elegant transparent sapphire crystal case back was developed and designed to meet the stringent Hallmark of Geneva criteria.

The new Vacheron Constantin Traditionnelle Chronograph Perpetual Calendar is fitted with a hand stitched black alligator leather strap secured by a 950 platinum folding clasp. An
authentic marvel on the wrist.
