The new Traditionnelle tourbillon and Traditionnelle complete calendar creations feature all the attributes of their proud lineage. Endowed with a stepped round case and lugs, slender bezel and a fluted caseback, railway-type minute track, Dauphine-type hands and “bâtons de Genève” hour-markers, they are driven by self-winding in-house movements revealed through the backs of their 18K 5N pink gold or 950 platinum case.
Traditionnelle tourbillon, in pink gold – Caliber 2160
The Traditionnelle tourbillon watch is a new milestone in the history of the Maison, since its 41 mm-diameter case in 18K 5N pink gold houses the first self-winding movement developed by Vacheron Constantin. In addition to the elegance of its openworked carriage shaped like a Maltese cross, the emblem of the Manufacture, Caliber 2160 is distinguished by its incredible slimness: this ultra-thin 188-part movement endowed with an approximately 80-hour power reserve measures just 5.65 mm thick. Its relatively sedate frequency (2.5 Hz), along with its 22K gold peripheral oscillating weight, provide a chance to admire the steady beating of its mechanism and the exceptional level of traditional finishing visible through the sapphire crystal caseback.
Traditionnelle complete calendar, in pink gold – Calibre 2460 QCL
This Traditionnelle watch equipped with a useful horological complication is powered by a mechanical self-winding movement: Caliber 2460 QCL, entirely developed and manufactured by Vacheron Constantin. Its 308 components include a 22K gold oscillating weight visible through the sapphire crystal back of the 41 mm-diameter case in 18K 5N pink gold. Beating at a frequency of 4 Hz and endowed with a 40-hour power reserve, this mechanism drives central hours, minutes and seconds hands, a complete calendar (showing the day of the week, date and month), as well as precision moon phase and the age of the moon indication. The remarkably accurate moon-phase indication requires just one adjustment every 122 years (compared with 3 years for a standard version).
