U-Boat is all about oversized cases, left-side crowns and resistance to the most extreme conditions. Its highly distinguishable watches were conceived of by Italo Fontana in the year 2000 after he had discovered drawings that his grandfather, Ilvo Fontana created in 1942 in response to a request by the Italian Navy to design watches for its pilots. Italo was inspired by those drawings and created U-Boat watches, billing it as “A New Dimension in Time.”
