Drawing inspiration from the magnificence of the marine world and its mysteries, iconic brand U-Boat crafts timepieces that are truly one of a kind. Blending the finest Italian craftsmanship with high quality and impressive technical performance, each watch carries a distinguished character - timeless and modern, ready for any occasion. Discover the stunning Darkmoon SS 9021, a refined and sophisticated watch that will elevate your wrist every day. When not worn, it holds up against temperature variations between 0°/+60°C. Designed for men, it pairs with any look, lending a masculine, captivating aura. Its round case is crafted from AISI 316L stainless steel and filled with a special oil featuring a visible air bubble that highlights the beauty of the dial while compensating for temperature changes. With a 40 mm diameter, it houses a screw-down crown on the left side for setting the hours and minutes. A high-quality domed sapphire crystal sits over the dial to protect it against shocks and scratches. On the back, the screw-down caseback ensures water resistance up to 5 ATM. It features an innovative locking system for quick and easy battery replacement.
With dazzling charm, a round metal dial adds an original and refined touch to the watch, creating a dimensional design on your wrist. Its sunray finish is dressed in a navy blue hue accented by brushed lines that give it a radiant, modern look. Two black baton hands sweep smoothly to indicate the hours and minutes. The hours are marked by two Arabic numeral indices at 4 and 8 o'clock, a "U" index - a nod to the brand name - at 12 o'clock, and baton indices for the remaining hours. These indices and the hands feature a beige SuperLuminova coating, keeping you on time even in low-light conditions. The brand signs its name and the founder's name at 12 o'clock, and at 6 o'clock displays the watch name and the temperature range within which it operates.
Known for its quality and precision, a Swiss-made quartz movement powers this watch with confidence. Oil-bath lubricated, it is specifically the Ronda 762 caliber, bringing the hands to life for accurate, reliable reading of hours and minutes.
This watch is fitted on an ultra-resistant vulcanized rubber strap built to endure any condition. In perfect harmony with the case and dial, it features a black finish contrasted by the brand's personalized embossed logo. It pairs effortlessly with any outfit, adding a modern touch to your wrist. At 18 mm wide, its steel tang buckle ensures a comfortable and secure fit throughout the day. Please note that the lug width is 20 mm.
This model offers water resistance up to 5 atmospheres, or 50 m. It is designed to be stunning and turn heads. That said, its refined look in no way compromises its ability to withstand the elements. You can wear it in the shower, though the Ocarat team recommends leaving it on the edge of the sink to preserve its brilliance and integrity over time. Swimming and diving, however, are strongly discouraged - doing so risks damaging the watch and incurring repair costs.
