U-Boat Sommerso Bronzo Ceramic 46mm

The Sommerso Bronzo Ceramic combines the warm, evolving patina of naturally aged bronze with the technical demands of professional diving. A brown ceramic disc sits within the unidirectional rotating bezel, chosen for its exceptional resistance to heat, scratching and colour fade even after long UV exposure. U-Boat’s distinctive left-side crown, with patented protection device, sits on the 46mm case, and the black, multi-layered dial with a visible ruby and beige Super-LumiNova markers is protected by a sapphire crystal with anti-reflective treatment. A Swiss automatic movement drives hours, minutes, seconds, date and a 24-hour indicator, running at 28,800 vibrations per hour with roughly 41-44 hours of power reserve. The watch is fitted on a hand-finished, naturally aged leather strap with a bronze buckle, and is rated to a genuine 300 metres of water resistance.
