U-Boat Sommerso

Description

Designed to withstand the demands of professional diving, the Sommerso pairs a 46mm AISI 316L stainless steel case, satin hand-finished, with U-Boat’s signature left-side crown and patented crown-protection device, plus a graduated unidirectional bezel for tracking elapsed dive time. The three-tier dial, finished with luminous markers, sits beneath 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, sealed in behind a caseback closed with seven external screws. The watch is completed with an ultra-resistant vulcanised rubber strap and is rated to a genuine 300 metres of water resistance.
