Urwerk is back with another beautiful demonstration of ergonomic ingenuity with the UR-120 Space Black. With its 44mm length, 47mm width, and 15.8mm thickness, the UR-120 features quite a smooth and flawless silhouette.

But before we explore this further, I have unnoticed a trend of URWERK suddenly launching way too many additions to their collection over a short span of time. Just this year we have already seen the UR112 “back to black”, the UR102 Reloaded, the UR-100V Magic T and now the UR120 Space Black. Correct me if I’m wrong but I don’t recall an independent watchmaking brand introducing so many additions over such a short span. Wonder what the strategy here is…

So what's new? To begin with, 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 to tell the time. This particular hour satellite morphs into the form of a V-shaped open hand. This time indication rotates on its own axis and splits 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.
