The U-Boat Watch Capsoil Doppiotempo IPB 8770/A combines the historic design of the 1938 Doppiotempo model with modern innovation. Featuring a 45mm black DLC-coated AISI 316L steel case, it includes dual crowns—one for time and date adjustment and the other for dual-time functionality via a rotating internal bezel. Its standout feature is the Oil Immersion technology, where the mechanism is submerged in an oil bath, creating a three-dimensional dial effect and the illusion of no glass. A compensation bubble floating on the dial adjusts to temperature changes, adding to the watch’s unique appeal. Rugged and sophisticated, this timepiece epitomizes U-Boat’s exceptional craftsmanship.
