U-boat has launched a new collection of watches in a 44mm size, following the success of the Darkmoon watch. This new collection features a curved dial under a domed sapphire glass, emphasizing the three-dimensional effect. The watch includes an electromechanical movement fully immersed in oil, with a black PVD-treated steel case and black dial. To enhance visibility in the dark, the numerals, indexes, and hands are treated with green luminova.
