U-Boat Darkmoon 44mm SS

Description

This Darkmoon model showcases U-Boat’s signature oil-immersion concept: the dial cavity is completely filled with a special fluid, producing a glass-free, three-dimensional display with a visible air bubble that compensates for temperature variation. The 44mm AISI 316L stainless steel case carries the brand’s distinctive left-side crown and is topped with a domed sapphire crystal, while the caseback uses an innovative locking-ring system for quick battery access. A precise Swiss quartz movement, itself lubricated in an oil bath, powers the watch, which is fitted on an ultra-resistant rubber strap and rated to 50 metres of water resistance.
