Built in Italy with a stripped-back dive watch aesthetic, the U1S-M pairs a matte black aluminum bezel insert with a vacuum-black dial marked by a clean white logotype and a raised lume dot filled with Super-LumiNova C1. Inside, the watch runs on the reliable Swiss Sellita SW200-1 automatic movement, delivering dependable mechanical performance beneath the minimal exterior. The case is matched with a black two-piece calf leather strap for everyday wear, while an included seatbelt-style NATO strap with brushed steel hardware offers a more utilitarian option.
