Urwerk reimagines the UR-112 Aggregat in a "Back to Black" model, inspired by the Bugatti Atlantic. Black DLC treated steel and titanium make up the streamlined yet complex architecture of the body. The grooved cover opens vertically to give access to the secondary power reserve and digital seconds indication. Revolving prisms showcase jumping hours and trailing minutes, which are visible in sapphire housing. This watch holds a 48 hour power reserve and comes on a black nylon strap. Limited to 25 pieces. “Once again we’ve let our guts speak for us in making a spaceship, a UFO that is a technical challenge. This UR-112 is pure madness in terms of the mechanics and finishes. The energy generated by the UR-112’s central engines is being distributed in four directions along no less than 12 axis. It’s actual mechanical lace. We will only be able to make a very limited number of them, but his is sheer, unadulterated watchmaking pleasure!” Felix Baumgartner, Urwerk co-founder.
