An Overseas dual time prototype

In tribute to the challenge taken on by Cory Richards

The Watch Quote™ - June 21st, 2019



To set the pace for his adventure on the slopes of Everest, Cory Richards wanted to have a watch enabling him to keep track of the time in Nepal, as well as back home in the United States. He chose an Overseas dual time.



In honour of his challenge and his constant quest to excel, the Manufacture created a prototype especially with him in mind and featuring an oscillating weight engraved with a design based on one of his Everest photos.



The 41 mm case is forged from sturdy and light titanium, while a reinforcement made of tantalum – a particularly hard metal – has been integrated beneath the bezel and the crown protection is reinforced by two titanium guards.



This model is fitted with an orange-stitched grey blue Ventile® technical fabric distinguished by its density along with its exceptional waterproofness. The sporty nature of the prototype is likewise expressed in the orange-accented grey blue frosted dial as well as in the NAC treatment applied to its movement.
