Vacheron Constantin’s Patrimony Traditionnelle World Time is the first mechanical watch ever created to indicate all 37 time zones simultaneously (including those offset from the UTC by a quarter of an hour). This new model is made possible by Vacheron Constantin’s patent-pending Caliber 2460WT, bearing the prestigious Geneva Hallmark. The display consists of three dials, including a uniquely shaded sapphire crystal disc that indicates day and night across the globe, a metal dial bearing a map and names of cities, and a metal chapter ring. Despite the highly technical nature of the watch, all indications can simply be adjusted with a turn the crown. The World Time is a truly extraordinary piece for the global jetsetter. Retail price is AUD $51,000.
