Vacheron Constantin released the Patrimony Traditionnelle World Time at the SIHH held this January.

The watch is equipped with the new Calibre 2460WT in-house movement bearing the Hallmark of Geneva. The world time indicates 37 time zones in increments of quarter and half-hour time differences. To highlight this important distinction those cities with an hour difference are shown with black letters and those with non-standard times in red. The dial is comprised of three levels. The first is a sapphire dial with day and night shading. The next dial has a “Lambert projector” type of map and the third dial has a metal chapter ring.

The rose gold Patrimony Traditionnelle World Time will be available September 2011 for a retail price of $39,900 USD.
