Traditionnelle Chronographe Quantième Perpétuel - Vacheron Constantin
The Manufacture is revisiting one of its most iconic models: the Traditionnelle chronograph 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 reflects the collection’s distinctive design codes in each and every detail: the stepped platinium 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.

Par souci de lisibilité, le cadran se présente en nuances de gris, avec des finitions différenciées selon les fonctions, comme les chronographes Vacheron Constantin des années 1940.

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. The small seconds and chronograph minute counters are distinguished by a circular-brushed ring with snailed centre. The 22K white gold moon disc, hand-finished, provides a symbolic depiction of a moon face that is alternately smiling or melancholy - a nod to historical pocket watches.

This sophisticated aesthetic approach is matched by the technical evolution embodied in the movement. Caliber 1142 QP, a state-of-theart movement entirely designed and developed within the Manufacture, 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.

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 minimise 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 vibrations/hour) so as to increase reliability and shock resistance.
