In a watchmaking landscape often dominated by rigid lines and established models, U-BOAT once again confirms its position as a brand that challenges the rules and reinvents the concept of time. Born from the creativity of Italo Fontana and deeply rooted in the tradition of Lucca, U-BOAT celebrates 25 years of nonconformity with the revolutionary U-65 collection, presented as a world premiere at Watches & Wonders 2025 in Geneva.

A hyper-curved design that catches the eye

The U-65 is immediately distinguished by its most iconic feature: an extremely domed sapphire crystal, which creates a unique and hypnotic three-dimensional effect. The 44 mm satin-finished 316L steel case is embellished with independent mobile lugs, screwed together using an exclusive system that ensures a perfect fit on every wrist, offering greater comfort than traditional hard-shell watches.

Skeleton dial and “Oil Inside” innovation

The three-tiered dial, inspired by industrial design and available in gray or black, exudes a bold, modern character. The true innovation is the "Oil Immersion" system, an exclusive U-BOAT technology already seen in the Capsoil and Darkmoon models. The Ronda 756 movement is immersed in a special fluid that amplifies the perception of depth and the convexity of the crystal, creating a never-before-seen visual experience.

This immersion creates a unique optical effect that makes the dial vibrant and almost alive, while a compensation bubble floats freely above the dial, interacting with the luminous indexes positioned at 12, 8 and 4 o’clock. The “arrow” hour and second hands, treated with Super-LumiNova in acid green, aquamarine and white, guarantee maximum readability even in the dark.

Functional minimalism: goodbye to the side crown

Unlike previous models, the U-65 eliminates the traditional crown on the left side, emphasizing the purity of its rounded silhouette. The time is set via a discreet pusher on the caseback, protected by the innovative Locking Ring System, which allows for simple and precise time adjustment. The caseback also features two screw-down ports: one for quick battery replacement and the other for refilling the battery, ensuring easy maintenance.

Strap and variants: comfort and futuristic style

The black silicone strap, soft and velvety to the touch, completes the model's contemporary and futuristic design. The collection currently includes three steel versions, all sharing the same philosophy of breaking with traditional norms, offering a timepiece that doesn't simply measure time, but proposes a new vision of it: more fluid, more dynamic, more hypercurved.


The U-BOAT U-65 OIL INSIDE isn't just a watch, it's a manifesto of creativity and innovation, a celebration of 25 years of courage and vision that continues to break the rules of traditional watchmaking. If you're looking for a watch that breaks the mold, combining industrial design, innovative technology, and a touch of boldness, the U-65 is the perfect choice.
