With the addition of the Sommerso line, which features a classy two-tone display and water resistance up to 300 meters, U-Boat has bolstered its assortment of diving watches. With a two-tone ceramic inlay in green and black and a satin steel case, it has a stylish and durable feel. The unidirectional rotating bezel also adds to this. An obvious ruby is located at 6 o'clock on the dial, along with a 24-hour indicator.
