The dial of the Overseas world time displays no less than 37 time zones, including those that are off-set by a half-hour or quarter-hour in relation to UTC time. The display comprises three parts. The centre features a “Lambert” projection map depicting the continents and the oceans, along with a translucent lacquered disc bearing the city names. A third sapphire disc laid over the map provides day/night indications by means of subtly graded smoky tints, synchronised with the 24-hour disc.
An ideal travel companion, the Overseas world time model features a 43.5 mm-diameter case housing Caliber 2460 WT. This self-winding movement patented, developed and crafted by Vacheron Constantin operates at a frequency of 28,800 vibrations per hour and enjoys a 40-hour power reserve. Its 22K gold oscillating weight bears a wind rose – a universal symbol indicating the cardinal points for travellers – adorned with sandblasted, polished and finely grained finishing. All the indications powered by this mechanism are smoothly and easily adjusted via the crown.
