The URWERK UR-150 Blue Scorpion is a timepiece designed to defy convention and deliver a spectacle of precision. Its signature feature is a flying carousel that carries three rotating hour satellites, while a retrograde hand sweeps across a 240° arc to track the minutes. At the turn of each hour, the hand snaps back in a lightning-fast return, while the satellites pivot and reposition themselves in a synchronized display. This fleeting transformation happens in a fraction of a second, creating both tension and fascination as the dial seems to shuffle and reset itself before the eye can catch it.
Behind this mechanical ballet lies an intricate dual system combining a cam-and-rack mechanism with a speed governor. These elements balance energy, control inertia, and ensure flawless synchronization. Each satellite is tilted at 10° to improve legibility, a detail that significantly raises the complexity of the movement. According to co-founder Felix Baumgartner, the true challenge is not the number of components but the precision of their interplay. The retrograde hand itself is an articulated metal skeleton, engineered to frame the active satellite, synchronize the jumps, and redistribute energy efficiently.
Beyond its technical achievements, the UR-150 Blue Scorpion is also a design statement. Its case flows seamlessly into a curved sapphire dome and ergonomic rubber strap, creating a sleek yet dynamic silhouette. The name may evoke danger, but the design embodies elegance and contrast. With its sculptural form and kinetic heart, the UR-150 is both a watch and a mechanical performance, an object that unites engineering, precision, and wonder on the wrist.
