Introduction
The U-Boat Left Hook watch was designed in the 1940's in the "Officine Fontana" laboratory of high precision instruments and components. Ilvo Fontana designed a professional wrist watch specific for pilots. Great sturdiness, immediate reading under all light conditions and high presicion. The project was not completed for commercialisation, due to the instability in Europe at that time... but a first batch of watches was produced. In 1999, Italo Fontana decided to resurrect his grandfather's project, from which he took his inspiration and developed a modern day time piece, combining a unique identity with a near dimension in time.
