The U-Boat Capsoil Chronograph Ref. 8109/E represents cutting-edge engineering, combining chronograph functionality with oil immersion technology to create depth, clarity, and long-term reliability.

Engineered for technical performance, this model is powered by a Swiss electro-mechanical chronograph movement lubricated in oil, delivering precise timekeeping and chronograph functions within a sealed environment.

Finished with industrial confidence, the black DLC-treated stainless steel case, curved sapphire crystal, and vulcanised rubber strap create a powerful, modern expression of U-Boat design.
