U-Boat Capsoil Doppiotempo SS

The Capsoil Doppiotempo combines U-Boat’s signature ‘oil immersion’ concept, where the dial is fully immersed in a special oil for a three-dimensional, glass-free look, with a dual-time function. Two crowns sit on the left side of the 45mm AISI 316L stainless steel case: one for setting the time, the other for adjusting the rotating inner bezel that tracks a second time zone in 30-minute increments. A domed sapphire crystal covers the dial, while the caseback uses an innovative locking-ring system for quick battery changes. The Swiss electromechanical movement is itself lubricated in an oil bath, and the watch is completed with an ultra-resistant vulcanised rubber strap, rated to 100 metres of water resistance.
