Description

The Traditionnelle World Time watch embodies a complication inextricably bound up with the history of the Geneva-based Manufacture, since it was in 1932 that Vachercon Constantin made its first timepiece equipped with a world time mechanism enabling simultaneous reading of the time in 31 cities of the world. Ever since, it has consistently perfected this useful and ingenious mechanism also referred to as ��universal�� or ��international�� time. This mechanical self-winding movement developed and crafted by Vacheron Constantin is distinguished by its ability to drive indications corresponding to the world's 37 time zones ÿ including those offset from Universal Coordinated Time (UCT) by a half-hour or a quarter hour ÿ complete with a day/night display via a central globe, as well as by its simplified crown adjustment of all indications. A patent for this exclusive association has been duly filed by the Manufacture.

The display consists of three parts: a sapphire dial with day/night shading as well as an engraved and inked 24-hour indication; a 950 platinum dial with a ��Lambert projector�� type map; and a metal chapter ring. All indications are easily adjusted via the crown, thereby considerably simplifying the use of this highly technical watch.

Ref. 86060/000P-9979 was introduced in anticipation of Watches & Wonders 2014.

Movement

Eager to make a major new contribution to the history of this complication, the Vacheron Constantin master-watchmakers and engineers have sought to create a mechanical movement capable of indicating not only the full time zones, but also the partial ones, so as to reflect the exact temporal reality in the 37 time zones. A number of countries have indeed adopted a half-hour or quarter-hour difference from UTC, and the Calibre 2460WT by Vacheron Constantin takes account of these specific characteristics. By way of example, it provides the correct time indication for Caracas, since Venezuela decided in 2007 to switch from a full time zone to a half time zone (GMT ÿ 4:30).

The indication of the 37 time zones as proposed by Vacheron Constantin in its Patrimony Traditionnelle World Time is as complete as one could wish for. The display consists of three dials: a sapphire dial with a unique 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 endowed with a 40-hour power reserve, mechanical self-winding Calibre 2460WT drives displays of the hours, minutes, central seconds and World Time. It enables simultaneous read-off of the time in all regions of the world, along with the day/night indication provided by the central world map. All indications are adjusted via the crown, thus considerably simplifying the use of this highly technical watch. In light of these exclusive developments, a patent has been filed for the new Vacheron Constantin Calibre 2460WT bearing the prestigious Hallmark of Geneva.
