Vacheron Constantin and its Swiss mechanical watches Featured

The Patrimony Traditionnelle World Time watch is a necessity for the man of the world
by 28 May 2011

In 1755 the master watchmaker Jean-Marc Vacheron dedicated his life to engineering state of the art watches. Very much a man of his time, Vacheron embraced early developments in international travel and ensured his watches kept pace. His engineering heir at the house of Vacheron Constantin, Louis Cottier, introduced the first international time mechanism in 1932. The first World Time watch with its eponymous “Cottier system” enabled simultaneous readings of the time in 31 cities. This marvel of the modern world paved the way for a number of ever more sophisticated prototypes – essential timepiece for noteworthy jetsetters from finance to film.

Eighty years on, Louis Cottier's World Time mechanism is moving into the next generation with the Calibre 2460 WT. This exclusive, soon to be patented with the exclusive Hallmark of Geneva, mechanism is the only one of its kind capable of displaying the exact temporal reality of each of the 37 time zones of the world – including those offset from the Universale Coordinated Time – such as Mumbai and Caracas – by the half or quarter of an hour. The Calibre 2460 WT pays tribute to Vacheron Constantin's pioneering role in the development of multiple time-zone watches.

The display consists of three dials: a sapphire dial with day/night shading; a metal dial with a ‘Lambert projector' type map; and a metal chapter ring. Beating at a frequency of 4 Hz (28,800 vibrations per hour) and boasting a 40-hour power reserve, the self-winding Calibre 2460 WT enables simultaneous readings of the time in all regions of the world, along with day/night indications provided by the central world map. All indications are adjusted via the crown, considerably simplifying the use of this highly technical watch.

Incorporating all Vacheron Constantin's signature characteristics, from the dauphine hands and slender bezel to its screw-down sapphire crystal case-back bearing the knurled motif, the new Patrimony Traditionnelle World Time comes with a 18K pink gold, 42.5-millimetre-diameter case, water-resistant to 30 metres.

“This watch is the perfect example of how we balance creativity and audacity with Vacheron Constantin's heritage and style. It's why we are considered the benchmark of watch-making.” Christian Selmoni, Artistic Director, declares.
