A modern expression of the grand Geneva watchmaking tradition, the aptly named Traditionnelle collection enriches its palette of horological complications this year with a complete calendar. Its case measures 41mm and comes in rose gold, or in platinum as part of the Collection Excellence Platine, which is limited to 100 numbered pieces.
Horological expertise, inimitable chic and refined style: The new Traditionnelle Complete Calendar features all the attributes of it proud lineage. Familiar features include the stepped round case and lugs, slender bezel and a fluted caseback, railway-type minute track, Dauphine-type hands and "bâtons de Genève" hour-markers.
A sapphire crystal window on the back shows off the watch's finely finished automatic movement, which was developed entirely in-house by Vacheron Constantin. The exhibition back also reveals the 22K gold rotor whose gyrations fuel the movement's (Caliber 2460 QCL) 40-hour power reserve.
In addition to displaying the hours, minutes and seconds, the watch has a triple calendar and a precision moon phase. The visual balance and legibility of the opaline silver-toned dial are accentuated by the unusual layout of the day of the week and month apertures, which are placed around the edge of the dial. The date is indicated by a slender, black central hand recognizable by its crescent-shaped tip.
This is in addition to the watch's remarkably accurate moon-phase indication. Unlike a standard moon phase that requires adjustment every three years, the one featured in the Traditionnelle Complete Calendar will not require an adjustment for 122 years.
For collectors, Vacheron will also introduce a Collection Excellence Platine edition of the Traditionnelle Complete Calendar. Limited to 100 pieces, it reflects all of the prestigious collection's aesthetic hallmarks: 950 platinum case, as well as the sand-blasted dial bearing the secret "Pt950" inscription between 4 and 5 o'clock. The dark blue alligator leather strap is hand-stitched with 950 platinum and silk threads.
