U-Boat Darkmoon Black Camouflage 40mm

This 40mm version of the Darkmoon brings the collection’s oil-immersion concept, where a special fluid fills the dial cavity for a distinctive three-dimensional, glass-free effect, to a more compact case size. A camouflage pattern decorates the black dial, with a visible air bubble that compensates for temperature changes. The AISI 316L stainless steel case keeps U-Boat’s left-sided crown and is topped with a domed sapphire crystal, while the caseback’s locking-ring system allows for quick battery replacement. The Swiss Ronda quartz movement is itself lubricated in an oil bath, and the watch is completed with an ultra-resistant black vulcanised rubber strap, rated to 50 metres of water resistance.
