Overseas World Time Silver

In Context

At 43.5 mm it is a large watch — well above this catalogue’s 40 mm median, and enough to dominate a narrow wrist. At 12.6 mm it is a tall case, and it will catch on a cuff. The case back is open, so the movement is visible without taking the watch apart, and the sapphire crystal will resist everything short of deliberate abuse. 150 m is genuine swimming resistance — more than the shape of this watch suggests it would need.

The movement winds itself from the motion of your wrist. 40 hours of reserve carries it overnight, but not through a weekend in a drawer. At 28,800 vph the seconds hand advances 8 times a second.

7700V/110A-B129 is one of 3 executions of the 7700V/110A base reference. Underneath they are the same watch; what separates this one is a silver dial and a stainless steel case. Introduced in 2460. Beyond the time it carries a gmt.

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 – 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.

9 other watches in the library run the Vacheron Constantin 2460 WT.
