Darkmoon

U-Boat first explored the idea of “oil immersion” with the innovative Capsoil collection. Now, with the Darkmoon collection, U-Boat has taken a quantum leap in that exploration, adding additional treatments to the 3D effect of the “oil immersion” technique. These watches also feature a variety of case material and treatment options, including vintage-style entirely handmade steel cases that utilize special overlaid and oxidized paints.
