The origin of U-Boat dates back to 1942 in Italy, when the Fontana family was commissioned to make watches for the officers of the Italian Navy submarines. They demanded as a requirement that the watches must had the maximum reliability and readability even exposed to the most extreme conditions.
Today, both automatic and quartz watches of this brand are handcrafted one by one in the Italian Tuscany, by using modern and unusual techniques and materials, most of which have never been used in the watchmaking industry before.
For instance, U-Boat created a patented system for releasing the crown that allows an easier adjustment of the date and time. In addition, the italian brand also patented a mechanism completely immersed in a low viscosity oil, such as the one that incorporates the Capsoil pieces.
