Overview

U-Boat Classico Tungsteno Chronograph Automatic Watch in green.

From the Classico line. Where U-Boat works a military-inspired design language that goes back to the drawings Ilvo Fontana made in 1942 for an Italian Navy commission intended for its pilots, rediscovered in 2000 by his grandson Italo Fontana, a 45 mm case in stainless steel 316L and a dial in green. At its heart beats an automatic movement. The case adds an anti-reflective sapphire crystal and water resistance to 10 atm. It comes on a leather strap secured with a buckle. Official U-Boat product, backed by the manufacturer's warranty.

Discover the sophistication of the tungsten chronograph, a true work of art that blends the strength of metal with the elegance of design, leaving a unique impression on your wrist. Equipped with a modified automatic mechanical chronograph movement according to U-Boat specifications, this watch features a polished tungsten bezel and a steel case back closed with 7 screws, revealing a U-shaped opening that allows you to appreciate the movement through the sapphire crystal. The three-level green metal dial, with details treated with beige superluminova and red hands, adds a touch of elegance. The aged leather strap, handcrafted in Tuscany, completes the experience with its dark brown color, reflecting the skill of skilled Italian artisans.
