Introducing the New U-Boat 44mm Darkmoon

U-Boat presents a version of the acclaimed Darkmoon model, in 44.80 mm steel, with a grey and black shaded dial, hands and indexes treated with white luminova.


odern and a classic of timeless elegance, gray is a nuance that could not be missing in the Darkmoon watch collection of U-Boat. Hence the creation of the new Darkmoon 44MM Grey SS, a watch that boasts, under the domed sapphire crystal, a shaded grey painted dial, emphasised by the iconic three-dimensional vision given by the “Oil Immersion” concept.

The 44.80 mm AISI 316L steel case is in fact filled with a special oil, which combined with the floating compensation bubble for temperature variations, creates an amplified view of the dial, as in the absence of glass, combined with a harmonious contrast given by the black hands and indexes and by the white numbers, all treated in white luminova.

The precision of the Swiss Ronda 712.3 quartz movement, lubricated in oil bath, allows the time-only function, while the case-back is characterised by the innovative locking system (Locking Ring System) with quick battery replacement.

The watch, waterproof to 50 meters, is completed by an ultra-resistant black vulcanised rubber strap customised with the embossed Maison logo with a pin buckle. The elegance of grey, the concept of “Oil Immersion” and the three-dimensional effect of the dial, all combined in a model ready to be worn on your wrist.
