The U-BOAT Profondo collection represents one of the most extreme expressions of technical and creative research by Italo Fontana. Born to push beyond the limits of conventional dive watches, it stands out for its imposing construction, technical materials, and unmistakable aesthetic, inspired by the ocean depths. Alongside the 46 mm models, the family expands with the new U-BOAT Profondo 50 mm, two even bolder interpretations of the Maison's most extreme diver.
The new Profondo 50 mm are available in two versions: one with an all-bronze case, featuring a handcrafted oxidation and patination treatment, and one with a titanium case and bronze bezel. The surfaces take on unpredictable shades ranging from antique gold to green and turquoise, making each piece unique. The contrast between titanium and aged bronze creates a distinctive balance of modernity, materiality, and vintage appeal.
The 50 mm diameter and 27.10 mm thick case embodies the entire personality of the collection. The sapphire crystal with anti-reflective treatment, measuring a substantial 11.30 mm, contributes to resistance against extreme pressures, while the unidirectional rotating bezel and the screw-down crown positioned on the left side of the case complete the timepiece's functional architecture. The automatic helium release valve and the patented Locking Ring System confirm the technical approach that distinguishes U-BOAT Profondo.
The most impressive feature remains the declared water resistance of up to 10,001 meters, a value that places these models among the most extreme interpretations of dive watchmaking. The three-level metal dial, with an aged finish and unrepeatable color nuances, is enriched by applied numbers and indices in beige Super-LumiNova, for an aesthetic result that recalls the visionary atmosphere of Jules Verne and the mechanical architecture of steampunk style.
Inside the new U-BOAT Profondo 50 mm is the Sellita SW200 Swiss automatic mechanical movement, modified according to U-BOAT specifications. The caliber operates at 28,800 vibrations per hour, features 26 jewels, and offers a power reserve of approximately 41 hours. The custom skeletonized metal rotor completes a movement designed to express solidity and technical identity.
Both new versions are limited and numbered editions of just 99 pieces each. The handcrafted bronze treatment makes each watch unique, while the handcrafted leather strap with an aged appearance and the titanium or bronze buckle, depending on the version, underscores the collection's material and artisanal character.
Alongside the new 50 mm references, the collection also includes the Profondo 10000 MT and Profondo 10001 Limited Edition at 46 mm, for those seeking a U-BOAT diver with different dimensions but the same extreme identity.
U-BOAT Profondo is a collection designed for those seeking an unconventional dive watch, where Italian design, technical materials, handcrafted workmanship, and extreme performance meet. A statement of personality by Italo Fontana, created for those who are not satisfied with merely measuring time, but want to push its limits.
