Classically inspired with its round case featuring a fluted back, its railway minute-track and its Dauphine-type hands, the Traditionnelle complete calendar openface model adopts an avant-garde profile with these two distinctive versions in pink and white gold.
Framed by a 41 mm case in 18K white gold or 18K 5N pink gold, they appear in an openface version with a sapphire dial. This transparency brings out the details of Calibre 2460 QCL/2, which adopts a contrasting anthracite grey colour achieved by NAC galvanic surface treatment. This new interpretation combining contemporary design and watchmaking heritage, is reminiscent of the Traditionnelle Twin Beat perpetual calendar model presented in 2019.
The characteristic features of the Traditionnelle collection including the stepped round case and lugs, the fluted caseback, the slim bezel, the railway minute-track, the bi-facetted Dauphine-type hands and the gold baton-style hour-markers embed these two models firmly in the watchmaking heritage of the Maison.
The opening onto the movement structure perfectly visible on both sides of the watch and featuring an anthracite grey colour achieved by NAC treatment highlights its mechanical power. Surrounded by a slate grey opaline flange on which a central hand points to the date, the upper part of the sapphire crystal dial features a likewise slate grey guilloché segment as well as applied gold hour-markers.
The resulting three-part dial overlooks the sapphire discs providing an aperture-type display of the days and months. The moon-phase disc, with its two realistic transferred depictions of Earth’s satellite, is also covered by a translucent sapphire mask. This airy construction provides a chance to admire the various movement components, including the bridges and mainplate featuring an original vertical upright finish on the front.
Beating at the heart of these two new timepieces is the in-house Vacheron Constantin Calibre 2460 QCL/2 with its 312 components. This calibre is an evolution of the 2450, the first self-winding movement entirely designed and developed by Vacheron Constantin. Equipped with a stop-seconds mechanism, it beats at a rate of 28,800 vph and is endowed with a 40-hour power reserve.
In addition to its triple calendar indications, it provides a precision moon phase display requiring only one correction every 122 years. The case back reveals all the finishes one would expect from an Haute Horlogerie movement, with a circular-grained mainplate, chamfered bridges and Côtes de Genève motif.
Water-resistant to 30 meters, these two Traditionnelle complete calendar openface models are fitted with a calfskin-lined grey alligator strap secured by an 18K 5N pink gold or an 18K white gold pin buckle with polished half Maltese cross.
