U-Boat U-65 3354 44 mm Quartz Watch

U-65 Hypercurve Timepiece

The U-Boat U-65 reference 3354 is a 44 mm stainless steel wristwatch built around the brand's Hypercurve philosophy. Its fluid, hyper-rounded case shape breaks from conventional watch design and targets the adult male buyer who wants a sports-style piece with a distinct architectural presence on the wrist.

Oil-Filled Dial and Mobile Lugs

A scratch-resistant hyper-domed sapphire crystal covers a gray skeletonised metal dial with three stacked levels. The dial cavity is filled with a special oil that amplifies legibility and creates the illusion of a missing crystal, while a visible air bubble compensates for temperature shifts. Patented mobile lugs let the 22 mm black silicone strap follow the wrist's natural curves, secured by a signed stainless steel buckle.

50 m Water Resistance and Caseback Crown

The watch is rated to 50 metres or 165 feet, suitable for splashes and brief immersion but not for swimming or diving. Time setting is handled by a discreet button at the centre of the solid caseback, which also integrates a locking system and a quick battery hatch for the Swiss Ronda caliber 756 quartz movement lubricated by an oil bath.
