A bronze version for the Sommerso, U-Boat's professional diver's watch: harder than steel and highly resistant to seawater and corrosion, this material is used to make the 46 mm case characterised by the unmistakable crown on the left side, with its patented protection device. The unidirectional rotating bezel with graduated hour-markers frames a dial composed of three superimposed layers with the upper one in black crossed by luminous beige hands and hour-markers, plus an additional counter for the 24-hour day and the date on the opposite side. Sommerso Bronze is equipped with a Swiss automatic mechanical movement, customised to U-Boat specifications, and is water-resistant to a depth of 300 metres. In addition, matching the case, it has a brown calfskin strap with a bronze buckle that has undergone a special anti-corrosion treatment.
