Urwerk has never been interested in telling time quietly.
With the UR-120 Blue Planet, the independent watchmaker pushes one of its most recognisable ideas into a more cinematic register, pairing its satellite display with a vivid blue PVD steel case and an unmistakable nod to space-age pop culture.
Limited to 20 pieces, it’s a watch for collectors who want mechanical theatre on the wrist rather than a conventional dial with hands.
At a glance
- The Urwerk UR-120 Blue Planet is a 20-piece limited edition of the brand’s futuristic satellite-display watch.
- Its split-cube hour satellites open into a V shape during the hour change, recalling Spock’s Vulcan salute.
- The watch is powered by the automatic UR-20.01 calibre, with a 175-component carousel and blue ALD finishing.
A blue case built for Urwerk’s mechanical theatre
The UR-120 Blue Planet places Urwerk’s angular watchmaking language in an azure-hued PVD steel case that looks closer to spacecraft architecture than classic horology.
That’s very much the point.
Urwerk’s identity has long been tied to alternative time displays, and the UR-120 continues that path with a case that frames the movement as a visible machine rather than hiding it behind traditional dial furniture.
The geometry is sculptural and assertive, with the blue treatment giving the watch a colder, more cosmic personality than a bare-metal execution would have.
The satellite display gets a Vulcan gesture
The UR-120 Blue Planet doesn’t use central hands to indicate the time.
Instead, it relies on Urwerk’s satellite system, where hour indicators travel around a minute track in a controlled orbital motion.
The drama arrives at the hour change.
Each satellite splits into two rectangular cubes, opening into a V shape before rotating on its own axis and closing again to present the next hour.
It’s a mechanical flourish with a clear science-fiction wink, recalling the Vulcan salute associated with Spock in Star Trek.
That detail could have been gimmicky in another watch, but within Urwerk’s world of wandering hours, planetary mechanisms and exposed kinematics, it feels unusually coherent.
Inside the UR-20.01 calibre
The automatic UR-20.01 calibre is built as a miniature mechanical laboratory, using a mix of beryllium-copper, brass, aluminium, ARCAP, titanium and LIGA-processed nickel.
Those materials are chosen for a mechanism that has to balance lightness, precision and visual impact while keeping the satellite display in motion.
At the centre of the system is a carousel made from 175 components, driving the triple planetary satellite arrangement.
The movement is also treated as an aesthetic object, with blue ALD decoration and yellow gold PVD accents adding contrast to the technical architecture.

The UR-120 Blue Planet is unlikely to convert anyone looking for a discreet dress watch, and it isn’t trying to.
Its appeal lies in how completely it commits to Urwerk’s particular vision of horology, where time is read through movement, mechanics and a little science-fiction theatre.
