U-Boat Capsoil Chronograph Ref. 8109/E showcases advanced electromechanical innovation housed within a bold 45mm case, where chronograph functionality is fully immersed in oil to enhance durability, precision, and visual depth.

The 45mm stainless steel case with black DLC treatment is completely oil-filled to create the illusion of an absent crystal and intensify dial contrast, complemented by a left-positioned crown and curved sapphire crystal.
