URWERK UR-120 'Spock' Guide: Specs, Editions, and Real Market Prices | Ultimate Watch

The URWERK UR-120 is the watch collectors point to when they want to explain why URWERK is not just another shaped-case indie. It arrived in 2022 as the follow-on to the UR-110, and the whole story is in the hour satellites. On the UR-110 the wandering hour cubes rode the minute rail as solid blocks. On the UR-120 each hour satellite splits: the cube opens into two arms that fan out into a V before closing again to hand off the hour to the next satellite. That V is why the nickname stuck. The collector world calls it the Spock, after the Vulcan salute, and Space Black even ships with a caseback engraved to that effect. We buy and sell serious independents on 47th Street, and the UR-120 is the kind of piece we get calls about all week. It is a 47mm sandblasted titanium and steel case, a crown up at 12 o'clock, swiveling lugs, and a curved sapphire that shows off one of the most theatrical time displays in modern watchmaking. Retail landed near CHF 100,000 at launch and the series closed in 2026 with the 20-piece Blue Planet. If you own one and want a real number, bring it to the counter.

Collector's Lore

Two things make the UR-120 a collector story rather than a spec sheet. First, the Spock name was never marketing at launch; the watch world coined it because the splitting-cube V looked exactly like the Vulcan salute, and URWERK leaned into it afterward, most visibly on the Space Black. Second, the UR-120 is the piece that proves the satellite wandering hour still had a new trick in it. Baumgartner and Frei could have restyled the UR-110 case and called it a day. Instead they built a cube that physically opens and closes as it hands off the hour, a mechanism that does nothing a solid block could not, and that is precisely why collectors love it. Owners tend to describe the same ritual: watching the satellite reach the left side, waiting for the arms to spread, and showing it to anyone within reach. That is the URWERK effect, and the UR-120 delivers it better than any reference the brand has built.
