The U-Boat Darkmoon 40mm Black SS 9018 is a timepiece inspired by the dark side of the moon. It features a 40mm AISI 316L stainless steel case filled with a special oil that enhances the black dial, creating an optical effect of a more intense black and higher legibility. The watch is powered by a Swiss Ronda 712.3 quartz movement, lubricated with an oil bath. The black painted metal dial has hands, numbers, and indexes treated with beige Super-LumiNova. A high-quality curved sapphire crystal protects the dial. The watch is water-resistant up to 50 meters and comes with an ultra-resistant black vulcanized rubber strap personalized with the U-Boat logo in relief. Reference number: 9018.
