The U-65 TEK SS watch is a testament to U-Boat's craftsmanship and innovation. The round case is crafted from 316L stainless steel, a material prized for its exceptional durability and resistance. With a black PVD finish, it strikes a look that is both modern and timeless. At 44 mm in diameter, this watch commands attention on the wrist while remaining remarkably comfortable. The domed sapphire crystal protects the dial, delivering perfect clarity and superior scratch resistance. The screw-down case back ensures both excellent water resistance and optimal protection for the movement.
The watch's dial makes a bold statement with vibrant colors including grey, black, and green. Large luminescent Arabic numerals at key positions deliver sharp legibility, even in the dark. The dial design is completed by equally luminescent hands that sweep across the timekeeping display with precision. The hours and minutes indications are presented in a visually striking way, making this watch as eye-catching as it is functional.
Powering this watch is a Swiss quartz movement from the renowned Ronda brand, specifically the Ronda 756 caliber. Known for its performance and reliability, this movement delivers remarkable accuracy for hours and minutes. Its standout advantage is an extraordinary battery life of up to 7 years on a single cell, virtually eliminating the hassle of frequent maintenance.
The watch's strap is crafted from black bovine leather, bringing a touch of elegance and understated style that perfectly complements the bold overall aesthetic. The 22 mm lug width provides a firm hold while allowing a degree of customization with other straps of the same size. Secured by a classic pin buckle, the strap stays firmly in place while remaining easy to adjust.
The U-65 TEK SS offers a water resistance rating of 5 ATM, corresponding to pressure resistance up to 50 meters of depth. While not a dedicated dive watch, this rating makes it fully capable of handling everyday splashes - handwashing, rain, or even brief submersion in water.
