Overview
U-Boat Classico U-46 Automatic Watch with Beige Dial.
The Classico collection traces its origins to the diving watch Ilvo Fontana designed in 1942 for the Italian naval forces, retaining the left-side crown featured in the original design. The U-46 takes its name from its 46 mm 316L stainless steel case and houses a Sellita SW 200 movement modified to U-Boat specifications.
The Swiss automatic movement powers the hours, minutes, seconds, date, and 24-hour indication beneath a sapphire crystal with anti-reflective treatment. The crown is capped, while the 316L stainless steel case back incorporates a smoked mineral-glass window over the movement. The rotor is skeletonized to U-Boat’s own design.
The three-layer painted metal dial has a beige finish and reveals a ruby in the movement. The hands, hour markers, and numerals are treated with Super-LumiNova for legibility in low-light conditions. The laser-cut dark brown leather strap is naturally aged and handcrafted in Tuscany, then secured by a steel pin buckle.

Questions & Answers
Where does the U-Boat design come from?
The design traces its origins to a drawing Ilvo Fontana made in 1942 for the Italian naval forces, a diving watch that remained on paper. His grandson, Italo Fontana, revived the design in Lucca and founded U-Boat around its proportions and distinctive left-side crown.
What does the 24-hour indication show?
The 24-hour indication uses a hand that completes one rotation per day against a 1-to-24 scale, allowing you to distinguish morning from evening at a glance while the main hour hand completes two rotations per day. The system has its origins in the 24-hour timekeeping used in marine and aviation applications.
What can you see through the dial?
The movement itself. The dial is openworked over the bridges and balance, revealing the wheel that regulates the watch as it oscillates several times per second while the watch is running.
How does a 46 mm case sit on the wrist?
It is a large watch. Compare the 46 mm diameter with a watch you already own before ordering, because the diameter determines the fit and is the measurement that photographs flatten. A loose cuff will fit over it.
How long does the Super-LumiNova stay lit?
Super-LumiNova is a phosphorescent pigment charged by exposure to daylight or artificial light. It provides its brightest illumination during the first few minutes and gradually fades over the following hours. Exposure to light recharges it for subsequent use.
