U-Boat Sommerso 46mm

This Sommerso model brings U-Boat’s professional dive-watch specification to a satin-finished 46mm AISI 316L stainless steel case, with the brand’s distinctive left-side crown, patented protection device, and a graduated unidirectional bezel for tracking elapsed time underwater. The three-tier dial is fitted with luminous markers and hands, and is protected by a sapphire crystal with anti-reflective treatment and a lens over the date window. A Swiss automatic movement drives hours, minutes, seconds, date and a 24-hour indicator, and the caseback is sealed with seven external screws. Rated to a genuine 300 metres of water resistance, the watch is fitted on an ultra-resistant vulcanised rubber strap.
