Vacheron Constantin is revisiting one of its most iconic models: the Traditionnelle chronograph perpetual calendar. Equipped with the new Manufacture Vacheron Constantin Caliber 1142 QP, this new creation, appearing in a 950 platinum version, combines two complications: the chronograph and the perpetual calendar.
With a classic round case, the new Traditionnelle chronograph perpetual calendar features 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.
The dial features various shades of gray 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 a snailed center.
The 22K white gold moon disc is hand-finished. 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 nod to historical pocket watches.
The movement of the Traditionnelle chronograph perpetual calendar is Caliber 1142 QP; entirely designed and developed within the Manufacture, it 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 new addition to the Traditionnelle collection will be able to keep track of all the vagaries of the calendar without any need for adjustments until March 1 2100.
The movement meets Hallmark of Geneva criteria. This emblem of Geneva’s watchmaking excellence applies both to the caliber itself and to the finishing of the watch as a whole, governed by demanding norms that make it one of the most exacting watch industry certifications.
The Vacheron Constantin Traditionnelle chronograph perpetual calendar comes on a handstitched Mississippiensis alligator leather strap secured by a 950 platinum folding clasp.
