Description

A longstanding part of the Vacheron Constantin watchmaking heritage, the World Time complication made a noteworthy comeback to the collections from the Manufacture in 2011. The Patrimony Traditionnelle World Time model houses the new Calibre 2460WT bearing the prestigious Hallmark of Geneva. Developed and manufactured by Vacheron Constantin, this new mechanical self-winding movement is distinguished by its capacity to indicate the world's 37 time zones, including those offset from Universal Coordinated Time (UCT) by a half- or quarter-hour ÿ an exclusive mechanism patented by Vacheron Constantin.

Despite its complex construction principles, the new mechanical World Time movement is extremely user-friendly. The wearer chooses the reference time and places it opposite the black triangle at 6 o'clock. The time in the reference location can then be read off either by the hour hand, or by the 24-hour disc, while the time in the other 36 time zones is simultaneously readable. The cities shown in black represent the full time zones, while the cities in red indicate half-hour or quarter-hour zones.

Incorporating all the signature characteristics of the collection ÿ a slender bezel, a knurled motif on the case-back, a screw-down sapphire crystal case-back, and dauphine hands ÿ the new Patrimony Traditionnelle World Time comes with a 42.5 mm diameter 18K pink gold case that is water-resistant to 30 metres. It is fitted with a brown alligator leather strap secured by an 18K pink gold folding clasp.

Due to the modern nature of this useful complication, along with the major innovations provided by its Calibre 2460WT, the Patrimony Traditionnelle World Time is destined to become an iconic model within the collection, and to perpetuate Vacheron Constantin's pioneering role in the development of multiple time-zone watches.

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.
