U-Boat U-65 Men's Black PVD Stainless Steel Watch

The U-Boat U-65 Men's Black PVD Stainless Steel Watch presents a bold evolution of the Hypercurve design, combining fluid case lines with an oil-filled construction that creates the illusion of a glass-free dial.

Powered by a Swiss Ronda 756 quartz movement lubricated in an oil bath, the fully oil-filled case intensifies colour depth and legibility while featuring a visible air bubble to compensate for temperature changes. The grey skeletonised dial is built on three stacked levels, finished with white Superluminova indexes and arrow-style hands.

Engineered for comfort and adaptability, the 44mm black PVD stainless steel case is paired with a flexible silicone strap and mobile lugs that naturally follow wrist movement. A hyper-domed sapphire crystal and 50 metres water resistance complete this technically innovative timepiece.
