U-Boat Capsoil Chrono DLC Watch

The Depth of Tuscan Fluid-Immersion Chronograph Engineering Handcrafted in Lucca, Tuscany, the U-Boat Capsoil Chrono 45mm SS (Ref. 8109 / 8109/D) encapsulates Italo Fontana’s pioneering liquid-immersion horological concept within a high-precision dual-counter chronograph. The AISI 316L stainless steel case houses a dial and movement cavity completely immersed in a specialized, low-viscosity transparent oil bath. This liquid immersion completely eliminates internal refraction and glare, producing a striking "glassless" visual effect with three-dimensional depth, extreme black contrast, and seamless readability from acute viewing angles. The deep black dial features luminescent beige Super-LumiNova markers, two chronograph sub-dials, and a dynamic compensating air bubble that moves fluidly across the dial to balance ambient temperature variations.
