URWERK UR-10 SpaceTime Blue Final Edition: A Cosmic Watchmaking Farewell

A 25-piece final edition that transforms the movement of Earth into mechanical timekeeping.

The URWERK UR-10 SpaceTime Blue Final Edition marks the conclusion of one of the brand’s most unconventional horological concepts. Limited to just 25 pieces worldwide, the new UR-10 does not simply display time – it transforms the motion of Earth itself into a wearable mechanical instrument.

Rather than focusing purely on hours and minutes, the UR-10 SpaceTime Blue visualizes our planet’s constant movement through space. Earth’s rotation, its orbit around the Sun, and the relationship between both trajectories become central elements of the watch’s display system.

With this final blue edition, URWERK closes the chapter on the UR-10 collection while reinforcing the philosophy that has defined the independent Swiss manufacture since 1997: time is not static, it is something we inhabit.

A Different Interpretation of Time

At first glance, the UR-10 appears surprisingly restrained for an URWERK creation. Its round dial gives it a more familiar silhouette compared to the futuristic satellite displays commonly associated with the brand. That apparent simplicity is intentionally deceptive.

The UR-10 remains one of the most conceptually ambitious watches ever produced by URWERK. Instead of using its complications to measure elapsed intervals or astronomical calendars, the watch visualizes the actual physical movement of Earth through space-time.

The dial integrates three separate subdials that reinterpret our planet’s motion mechanically.

At 2 o’clock, the “Earth” counter measures the distance traveled through Earth’s daily rotation, displaying every 10 kilometers traveled at the equator.

At 4 o’clock, the “Sun” counter tracks Earth’s orbit around the Sun, displaying every 1,000 kilometers traveled through space.

At 9 o’clock, the “Orbit” counter combines both trajectories into a synchronized dual-scale display representing planetary rotation and solar revolution simultaneously.

The result is less a traditional wristwatch and more a mechanical cosmography designed for the wrist.

A Watch Inspired by Cosmic Motion

According to URWERK co-founder and artistic director Martin Frei, the UR-10 was designed to shift the wearer’s perception of time itself.

Instead of treating time as an isolated measurement, the watch places the wearer inside a much larger cosmic mechanism.

The new blue edition reinforces that philosophy visually. The ADLC-treated blue dial evokes the darkness of space while contrasting with the metallic architecture of the counters and hands.

Circular satin finishing, sandblasted textures, and layered surfaces create a highly technical appearance that remains unmistakably URWERK.

The Caseback as a Mechanical Cosmography

The reverse side of the UR-10 SpaceTime Blue continues the astronomical narrative.

A peripheral hand traces the hours along a 24-hour scale while engraved pictograms represent Earth’s rotation and revolution around the Sun. Rotation is displayed clockwise while revolution is shown counterclockwise, creating an additional visual representation of planetary movement.

Rather than functioning as a decorative caseback, the rear display extends the conceptual framework of the watch.

The UR-10 becomes a portable mechanical model of Earth’s movement through space.

Double Flow Turbine Technology

Inside the watch is the Calibre UR-10.01, an automatic movement equipped with URWERK’s patented Double Flow Turbine system.

This self-winding architecture uses two counter-rotating turbines designed to regulate airflow and reduce excessive rotor speed when the movement is not actively winding.

The system protects the winding mechanism from unnecessary stress while simultaneously creating a hypnotic visual effect inside the movement architecture. The caliber operates at 28,800 vibrations per hour and delivers a 43-hour power reserve.

A Legacy Rooted in Antique Astronomy Clocks

The conceptual origins of the UR-10 trace back to an antique astronomical clock restored by Gérard Baumgartner, father of URWERK co-founder Felix Baumgartner.

The historic clock, originally created by Gustave Sandoz, featured multiple astronomical displays that inspired the cosmic philosophy behind the UR-10 project.

As with many URWERK creations, the mechanics are never purely decorative. Every indication exists to visualize an abstract concept mechanically. The UR-10 SpaceTime Blue represents the final evolution of that idea.

The Final Edition of the UR-10

The UR-10 SpaceTime Blue Final Edition officially closes the UR-10 collection.

At URWERK, discontinued models are not replaced or reinterpreted indefinitely. Once production ends, they enter the brand’s “Legends” archive collection.

This final edition therefore serves both as the conclusion of the UR-10 concept and as a tribute to one of the most intellectually ambitious watches in contemporary independent watchmaking.
