Vacheron Constantin’s Traditionnelle collection, which perpetuates the spirit of Geneva’s watchmakers during the Age of Enlightenment, adopts a highly sophisticated style with two new models equipped with a complete calendar.
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.
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. The “openface” design highlights the technical nature of the Traditionnelle complete calendar openface watch. This complication, also known as the triple calendar, indicates the date, day and month, complemented on these models by a moon phase.
Beating at the heart of these two new timepieces is 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 vibrations per hour 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.
