The Latest URWERK UR-120 Space Black Fundamentally Transforms Perception

The second iteration of the UR-120 Space Black fuses advanced technology, celestial inspiration, with a touch of science fiction, captivating horological enthusiasts across the galaxies.

The UR-120 is a beautiful demonstration of ergonomic ingenuity, combining form and function in perfect harmony with its 44mm length, 47mm width, and 15.8mm thickness. With the upper part of the case seamlessly smooth, devoid of any screws, the UR-120 features a flawless silhouette.

Martin Frei explains: “The UR-120 Space Black is all about the power of black in design. The use of black not only exudes elegance but also fundamentally transforms our perception of the object. Black works its magic by subtly distorting our judgments of size, while intensifying the watch’s contours to create a truly mesmerizing effect.”

To tell time, the UR-120 features a new revolving satellite complication: analog minutes and a never seen before split open digital hour satellite mounted on planetary gears. This particular hour satellite morphs into the form of a V-shaped open hand. This time indication rotates on its own axis, split open to unveil its secrets smoothly.




Powered by the caliber UR-20.01, the UR-120 harnesses the energy of the stars within its intricate mechanism. The central carousel, equipped with three arms, gracefully carries the satellites that bear the hour markers on all four sides. As the satellite traverses the minute track, it reaches the left part of the case, setting in motion a sequence of movements. The satellite splits open, revealing two rectangular studs. They take on a V-shape, reminiscent of the Vulcan salute. Once separated, both studs spin on their own axis and shut, all in order to display the new hour unit.

There is a triple revolution taking place under the hood of this spacecraft: the satellite-bearing carousel spins on a central axis, each satellite counter-spins in order to remain upright and therefore readable and each stud spins on its own axis.

The Persistence of Memory – URWERK: The Blade Runners

Felix Baumgartner, co-founder and master watchmaker of URWERK, expresses his enthusiasm about the extraordinary challenges faced during the development of the UR-120: “On the part alone governing the partition of our satellite time, there are more than 175 components. These intricated parts meticulously crafted with our CNC machines, rock and roll with micron-level exactitude. This ‘Vulcan salute’ complication we dreamt of and created is synonymous with live long and prosper still it cost us a few hours of our lives and quite some stress, but the result is definitely worthy of our efforts.  This achievement is nothing short of spectacular!”
