URWERK has never been interested in making time look conventional, and the UR-120 Blue Planet is a sharp reminder of why the brand still sits apart in independent watchmaking.
This final version of the UR-120 turns the model’s wandering-hour architecture into something darker, bluer and more celestial, with gold accents used to draw attention to the parts that actually move.
It’s a watch for collectors who like their mechanics visible, their design language futuristic and their horology served with a distinct science-fiction pulse.

At a glance
- URWERK’s UR-120 Blue Planet is the final edition of the UR-120 series and is limited to 20 pieces.
- The watch uses the automatic calibre UR-20.01 with satellite hours, analogue minutes and split-hour modules that open into a Vulcan salute.
- It is priced at CHF 115,000 excluding taxes and comes in a blue-toned sandblasted steel case on a blue Cordura-textured calfskin strap.
A blue steel shell for the UR-120 farewell
The UR-120 Blue Planet keeps the familiar spacecraft-like silhouette of the series, but its mood is noticeably different.
Instead of titanium, URWERK has chosen sandblasted steel for the case, giving the 47 mm by 44 mm form a denser visual presence and a more architectural surface.
The case measures 15.8 mm thick without the crystal, which places it firmly in statement-watch territory, yet the proportions remain central to the object’s identity.

This isn’t a thin dress watch trying to disappear under a cuff.
It’s a mechanical vessel built around display, motion and wrist presence.
The case is made from two principal sections, with the base and upper shell meeting in a clean protective form.

That kind of construction gives the watch its smooth, almost sealed quality, while still allowing the dial-side mechanics to feel exposed and active.
Articulated lugs help extend the case visually, but there’s a practical detail hidden in the 6 o’clock lug.
A spring system allows the fit to adjust on the wrist, a useful touch on a watch with this much width and sculptural mass.

Gold mechanics against a deep blue field
The colour treatment is the most immediate difference between the Blue Planet and earlier UR-120 executions.
The case and display lean into a blue that shifts toward black depending on the angle, giving the watch a sense of depth rather than simple brightness.
URWERK uses that blue as a quiet stage, then lets gold pick out the kinetic components.

The lyre springs and Maltese crosses are treated with a 24K yellow-gold PVD coating, so the eye naturally follows the parts responsible for the watch’s movement and transformation.
It’s a smart use of contrast because the gold isn’t decorative for its own sake.
It signals where the action is happening.
The dial surface is deliberately free of visible screws and clutter, allowing the satellites and minute track to dominate the experience.
In low light, the Super-LumiNova-filled satellites add another layer to the display, making the watch feel even closer to an instrument from a speculative future than a traditional wristwatch.
The calibre UR-20.01 and its wandering-hour theatre
The UR-120 Blue Planet is built around the automatic calibre UR-20.01, a movement that treats timekeeping as choreography.
Three hour satellites orbit a central carousel, with each satellite taking its turn along the minute track before handing over to the next hour.
The display is easy to understand once you’re familiar with the logic, but it never feels ordinary.
That’s the core appeal of URWERK’s work, where reading the time becomes part mechanical observation and part ritual.
The UR-120 adds a memorable flourish when a satellite reaches the left side of the case.
It splits open into two rectangular arms that form a V shape, a gesture immediately recognisable to science-fiction fans as the Vulcan salute.
The reference could have felt gimmicky in a less technically serious watch.
Here, it works because the movement engineering is substantial enough to support the theatre.
The carousel alone is composed of 175 components, and the sequence depends on URWERK’s Maltese cross element and lyre-shaped spring.
The result is a display that feels playful without being unserious.

As the closing chapter of the UR-120, the Blue Planet feels appropriately committed to the ideas that made the series distinctive.
It’s technical, visual and slightly eccentric, with just enough restraint in its blue-and-gold palette to keep the spectacle focused.
For the collector drawn to independent watchmaking at its most animated, this final UR-120 is less a conventional timepiece than a compact mechanical spacecraft for the wrist.
