A fresh interpretation of a legendary timepiece certified with the Hallmark of Geneva

The Manufacture is revisiting one in every of its most iconic models: the Traditionnelle chronograph perpetual calendar. Equipped with the brand new Manufacture Vacheron Constantin Caliber 1142 QP, this timepiece perpetuates the custom of excellence cultivated by the best Geneva watchmakers.

With this new creation showing in a 950 platinum and 18K 5N pink gold variations,Vacheron Constantin has opted to mix two key Fine Watchmaking problems: the chronograph and the perpetual calendar.

Technique meets elegance
With its basic spherical case, the Traditionnelle collection by Vacheron Constantin embodies the values cherished by the Maison, combining tradition and formal elegance with supreme mastery of horological problems. The brand new Traditionnelle chronograph perpetual calendar is the final expression of this profitable synergy. The collection’s distinctive design codes are mirrored in every element: the stepped case with a particular fluted sample on the again, the dauphine-style arms and the railway-type minute observe. A white or black tachymeter scale surrounding the dial accentuates the technical nature of the watch.

Limpid display
Exemplifying a priority for legibility, the dial options varied shades of gray with finishes that differ in line with the capabilities, reflecting the structure of 1940s Vacheron Constantin chronographs. Standing out in opposition to a slate- or silvered-coloured opaline base, the small seconds and chronograph minutes counters are distinguished by a circular-brushed ring with snailed centre. The 22Ok white gold or pink gold moon disc is hand-finished in step with the effective custom of inventive crafts cultivated by Vacheron Constantin. Positioned within the centre of the date counter, it offers a symbolic depiction of a moon face that’s alternately smiling or melancholy, relying on the trail of the Earth’s satellite. A subtle nod to historic pocket watches.

Subtle evolution
This subtle aesthetic method is matched by the technical evolution embodied within the motion of the Traditionnelle chronograph perpetual calendar. Caliber 1142 QP, a state-of-theart movement entirely designed and developed throughout the Manufacture, replaces the 1141 QP. The brand new motion drives the perpetual calendar functions – with indications of the days, date, months, leap years and moon phases – in addition to the chronograph functions with a direct-drive seconds arms and 30-minute counter at three o’clock, positioned reverse the small seconds at 9 o’clock. This newcomer to the Traditionnelle collection will thus be capable to hold observe of all of the vagaries of the calendar with none want for changes till March 1st 2100.

High standards certified by the Hallmark of Geneva
With the event of this new caliber, the Vacheron Constantin watchmakers and developers have been keenly attentive to the vitality constraints regarding the chronograph capabilities, with the intention to minimise their influence on the 48-hour energy reserve. The oscillation frequency of the stability has additionally been raised from 2.5Hz to three Hz (21,600 vibrations/hour) in order to extend reliability and shock resistance. Like all Vacheron Constantin movements, this new caliber seen by a chic clear sapphire crystal caseback was developed and designed to fulfill the stringent Hallmark of Geneva criteria. This emblem of Geneva’s watchmaking excellence applies each to the caliber itself and to the ending of the watch as a complete, ruled by demanding norms that make it one of the rigorous and famend watch business certifications.

The Vacheron Constantin Traditionnelle chronograph perpetual calendar is fitted with a handstitched Mississippiensis alligator leather-based strap secured by a 950 platinum or 18K 5N pink gold folding clasp. An authentic marvel on the wrist.
