U-Boat Classico 46 Sommerso BK 9007 Stainless Steel & Black Automatic Wristwatch
Ilvo Fontana, crafter of precision engineering instruments, received a presitigious commission from the Italian Navy: to design and build a new model of watch for its pilots. This challenge meant satisfying the high quality standards of the Navy and respecting very precise technical specifications, but above all guaranteeing maximum visibility and reliability in any light and weather condition; however, circumstance at that time did not allow the project to materialize. In 2000 Italo Fontana, Ilvo's grandson, came across these precious designs, which were to become his source of inspiration for the creation of the first U-Boat watch and his new dimension in time. Every single U-Boat timepiece is handcrafted in Italy by master craftsmen, dedicated to the highest level of precision engineering and finishing, where care and attention to detail span the entire process, from the very first prototype to the final assemblage of the watch. A made in Italy in all details.
