The U-Boat watches Darkmoon goes beyond the boundaries of traditional design, combining innovative features with retro style lines. The Swiss electromechanical movement is completely immersed in a low viscosity lubricating oil. The oily liquid flows into the dial producing an absolute and deep black colour within an ever-moving compensation bubble, that surprisingly amplifies the view of the hands that seem to flow free as in the absence of the glass.The IP Bronze case is completely filled with a special oil that emphasizes the dial, creating an optical effect of a more intense black and higher legibility. Curved mineral glass and laser-cut strap handmade from hand-finished leather.
