The Vacheron Constantin Overseas Dual Time Prototype was first designed for explorer-photographer Cory Richards when he prepared to climb Mount Everest. Richards wanted a watch that he could use to check the time in Tibet and the US simultaneously — a dual time watch.

The 41mm titanium watch is both lightweight and legible. Able to survive extreme weather conditions, the titanium case is reinforced by tantalum, a rare corrosion-resistant metal. As can be seen from the back, the highly decorated gold rotor bears the image of Everest as captured by Richards.

For now, it’s a prototype, but there is a growing push for the Overseas Dual Time to go into full-scale production.
