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.
