Vacheron Constantin Traditionnelle Complete Calendar Openface
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. The openworked sapphire dial reveals Calibre 2460 QCL/2, whose mainplate and bridges are highlighted by anthracite NAC treatment. The triple calendar display, complemented by a precision moon phase, gains in depth through its functional and contemporary style.
Revisiting the fine historical traditions of Geneva watchmaking
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. This new interpretation combining contemporary design and watchmaking heritage, is reminiscent of the Traditionnelle Twin Beat perpetual calendar model presented in 2019.
Airy construction
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.
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.
