The U‑Boat Capsoil Chrono DLC is a bold 45 mm chronograph crafted from matte black DLC-coated stainless steel. Its fully oil-filled case creates a deep, distortion-free dial effect, enhanced by a curved sapphire crystal and a visible compensating air bubble. Powered by a Swiss electro-mechanical quartz movement, it offers precise chronograph functionality with a left-positioned screw-down crown. The black dial features beige Super-LumiNova hands and markers for optimal visibility. Finished with a black vulcanized rubber strap and water-resistant up to 10 ATM, this timepiece blends technical innovation with rugged, modern design.
