 The UR-230 “Black Star” plunges URWERK back into Black

URWERK ends the year in sidereal black. The independent watchmaking house unveils its new UR-230 “Black Star,” a creation that does not seek light but instead absorbs it, engulfs it – the better to restore it on its own terms.

After the raw texture of the Carbon CTP in the “Eagle” and the mineral whiteness of the ceramic “Polaris”, the “Black Star” concludes the 230 collection triptych on a cosmic note. The curtain falls on a note of vibrant black: a gravitational field where light vanishes, only to be reborn in random flashes.

Welcome to the dark side of the URWERK force!

 A HIGHLY PROTECTED MECHANISM

This UR-230 “Black Star” is original in more ways than one. First, there is its structure. Calibre UR-7.30 powering this creation is protected by a hermetic titanium container designed as a mechanical safe.

Surrounding this highly protected heart, a composite ceramic case and a black DLC titanium back form the UR-230's shell: “I love the aesthetics of ceramic and its clean, precise look. It's a material that's hard, shiny, beautiful... and incredibly fragile. A single impact and it cracks – yet I didn't want to give up on this option”, explains Felix Baumgartner, master watchmaker and co-founder of URWERK. “We had to find a solution to fulfil this desire without making any comprises.”

The original, high-performance case of the UR-230 “Black Star” is made from a laminated composite ceramic developed specifically for URWERK: layers of braided ceramic, fibreglass and carbon fibre have been integrated into a polymer matrix.

When machined, this unique ceramic reveals a shiny relief. Its flat, smooth surface is illuminated with sparkling dots, creating a dense, vibrant black-light texture.

VIBRANT DARKNESS

“While Polaris evoked the brightness of the North Star, Black Star belongs to the interstellar void”, says URWERK’s artistic director and co-founder Martin Frei. "This black is not there to conceal. It breathes. It makes light appear in a setting of shadows. In astrophysics, a Black Star refers to the state of a collapsing star. The star then absorbs light like a black hole, but not completely, just at the cosmic boundary between being and disappearing. URWERK's ‘Black Star’ embodies this paradoxical presence: a deep, living black that does not deny light but reveals it by draping it in shadows – a glow born from the very heart of the night."

 WANDERING MECHANICS

The UR-230 “Black Star” embodies URWERK’s DNA. This new UR-230 features a satellite complication with wandering hours and a retrograde 3D hand; while a central hub connects three cubic hours satellites. These four-sided blocks move across a 120° sector in 60 minutes.

The active hour – the one scrolling along this minutes rail – is taken charge of and put into orbit by an openworked retrograde hand that accompanies it throughout its journey from index 0 to 60. At the end of 60 minutes, the hand instantly flies back to zero to take charge of the next satellite.

DUAL TURBINE SYSTEM

The UR-230 is a self-winding watch regulated by an exclusive dual turbine system:

• - one absorbs external shocks
• - the other regulates the air flow of the automatic winding mechanism, acting as a true aerodynamic brake.
• A control on the back allows the rotor load to be adjusted or even completely deactivated to switch to manual-winding mode.
• Two symmetrical indicators − at 11 o'clock and 1 o'clock − display these settings.

This UR-230 “Black Star” concludes the 230 collection chapter. The end of a story, but with new adventures to follow in 2026...

 UR-10 SpaceMeter
Watches measure time. The UR-10 measures time and space

Click , to see the large size. ▶ BIG FOTO   

The UR-10 is more than a milestone in URWERK's trajectory. It's the coalescence of time and space, legacy and freedom, science and emotion. It allows URWERK to reinvent itself while staying true to its core beliefs.

At first glance, a paradox unfolds: a round dial, hands in the center, concentric counters... features that seem alien to URWERKS DNA, yet in truth reveal a new facet of the company’s ethos. 

An URWERK unlike any other before.

This is an URWERK with a dial, a round case and an almost sacrilegious pair of hands in the center. On paper, the UR-10 appears to be a radical departure for the company. However, upon closer inspection, it is unequivocally a member of the 'Special Projects' family, the outlier, out-of-the-box, groundbreaking collection URWERK is so adept at creating.

Click , to see the large size. ▶ BIG FOTO 

While the UR-10 features three sub-dials, it is not a regulator. Nor is it a chronograph or any form of calendar watch. Its subsidiary indications do not measure the passing of time. The UR-10 is dubbed a SpaceMeter for good reason: it measures the distances our planet travels across the time-space continuum. A world first! 

Click , to see the large size. ▶ BIG FOTO 

And its three sub-dials are as many astronomic instruments: 

•    At 2 o'clock, the counter marked EARTH measures every ten kilometers the Earth travels in its daily rotation, in increments of 500 meters. 
•    At 4 o'clock, the counter marked SUN advances in 20 km steps, registering every 1’000 km the Earth travels on its solar orbit.
•    At 9 o'clock, the counter marked ORBIT combines both trajectories, thus inscribing every 1,000 kilometers of rotation and 64,000 kilometers of solar orbit on two synchronized scales. 
•    On the back of the case, a peripheral hand traces the hours on a 24-hour scale, mirroring a full rotation of the Earth. The caseback is engraved with indications of both Rotation and Revolution: Rotation reads clockwise, while Revolution is read anticlockwise. This striking opposition reflects the Earth’s own anticlockwise revolution, a poetic reminder of the cosmic dance.

Martin Frei, Art Director and Co-Founder of URWERK, remarks, « Time and Space are the same reality. The UR-10 depicts two characteristics of our earthly condition; to be bound by human time, and to be mere passengers on a planet constantly traveling through the cosmos. »

A family affair

The Baumgarter family history was instrumental to the creation of the UR-10. Felix's grandfather was a watchmaker, while his father, Gérard, restored ancient clocks, a role he performed with great distinction. Felix, too, followed in the footsteps of his forefathers by embracing watchmaking. Yet where they honored tradition, he preferred to pursue a resolutely contemporary, at times futuristic vision of horology.

In 1996, Gérard Baumgartner uncovered a singular pendulum clock signed by Gustave Sandoz, an unsung master of 19th century chronometry who happened to be France's Horologist-Mechanic by appointment to the King and the Navy from 1874. Intrigued by the prestigious signature, Gérard acquired the timekeeper despite its inner workings proving unfathomable to him.

Before him stood a clock with three sub-dials, that seemed unrelated to any conventional time display, and a pendulum that beat far too quickly. Patiently, Gérard unraveled the enigma, eventually discovering a planetary trajectory tracker - a mechanical marvel designed to measure Earth’s rotation. Conceived on the principle of a regulator, it revealed the distance travelled by our planet across three distinct time scales.

“This gift became a true bridge between two worlds: my father’s devotion to classical horology, and URWERK’s quest for disruption. It was the spark that ignited our UR-10 — the very first chronometer to express Earth’s movements in kilometers.’”

Core creations

« We've put a lot of love in this timepiece. And a lot of energy as well, adds Felix Baumgartner. We've partnered with Vaucher Manufacture to develop this base movement, to comply with its demanding technical and design constraints. »

On the other hand, the URWERK complication module - conceived entirely in-house - opened up new challenges in weight and energy management, a field that has always been at the core of URWERK’s philosophy.  

  Click , to see the large size. ▶ BIG FOTO   

« As always, we've pushed research and development to the far reaches of our expertise, analyzing the most minute detail to retain nothing but the essential, says Felix Baumgartner. Five wheels, five axes, a lot of rubies to lessen friction and an exacting focus on power, all in order to express two different rhythms in a single movement. We used skeletonized LIGA wheels, some of which weight 0.015 gram and down to 0.009 grams, the same as an eyelash, in order to save as much energy as possible. This preserves the concept's inherent poetry along with its resistance and accuracy. »

Another horological development relating to the UR-10 is the addition of a Double Flow Turbine, an evolution of URWERK's one-way self-winding system. This patented turbine comprises two stacked propellers which rotate in opposite directions. 

Click , to see the large size. ▶ BIG FOTO 

When a self-winding mechanism isn't spinning in the winding direction, the rotor's high speed exerts high constraints on the system. The double turbine creates air flow between the two sets of blades, which slows them down and preserves the mechanism. These blades also create a hypnotizing spectacle. 

Made on the third rock from the sun

The steel and titanium case is just 7.13 mm in height, making it one of the thinnest ever made by URWERK. And it's as wildly complex as one would expect. The titanium upper case and the steel caseback are fitted into one another and sealed shut with a longitudinal screw.

“The case is clean and symmetrical, but it has a very specific construction, says Martin Frei. It's screwed from the sides, like Gérald Genta used to do it. That structure is typical of some iconic watches. It only has two parts and no caseband: it's simple but in fact extremely complex.”

On this occasion, URWERK has crafted the hands and dial of the UR-10 within the confines of its workshop and finished them to a flawless conclusion. 

Primordial momentum

To conclude, the UR-10 is an invitation to reconsider what URWERK represents. Beyond satellite hours, the brand's actual nature rests on three pillars. 

Click , to see the large size. ▶ BIG FOTO   

The first one is a fundamental human connection. The legacy and transmission within the Baumgartner family is one side of that coin. The other is the organic and unbreakable bond between its two founders. 

Click , to see the large size. ▶ BIG FOTO 

 The second one is a perpetually changing contemporary design language. From evolution to update, from reinterpretation to quantum leap, shapes and details are always in a state of flux. 

Click , to see the large size. ▶ BIG FOTO   

The third one is the symbiotic meshing of that design with a horological invention force that's also constantly evolving. Whether it's the display, materials, finishing, torque calculations or a quest for lightness, URWERK is first and foremost a watchmaking trailblazer.

Martin Frei has the final word :  "The UR-10 is a philosophical reflection on our place in the universe; a spirit evident in each URWERK creation."

"The deadly Sting of the Blue Scorpion”
URWERK’s Killer New Blockbuster

  Click , to see the large size. ▶ BIG FOTO  

Urwerk has never followed the rules and always played by its own. This time, it sharpens its edge with the launch of the UR-150 Blue Scorpion: a machine that stings as much as it dazzles.

  Click , to see the large size. ▶ BIG FOTO  

At the heart of the UR-150, a mechanical drama unfolds on a hundredth-of-second scale as a flying carousel places the three pivoting hour satellites into orbit, while a tautly poised retrograde hand sweeps across a 240° arc on the dial at each change of hour. All this in a mechanical effort on the brink of chaos, yet perfectly controlled...

  Click , to see the large size. ▶ BIG FOTO  

With the UR-150, Urwerk invents a genuine satellite complication, unveiling a fresh kinetic art.

A breathtaking mechnical show

Beneath a sapphire dome stretched like a bow, a mechanical creature comes to life: three hours’ satellites are mounted on a constantly rotating flying carousel. 

  Click , to see the large size. ▶ BIG FOTO 

The active satellite – that which indicates the current time – is highlighted by a retrograde hand that accompanies it from minute 0 to 60. 

  Click , to see the large size. ▶ BIG FOTO 

At the 60th minute, this retrograde hand performs a lightning-fast 240° return, while the three satellites each pivot on their axis and simultaneously rotate 270°.

  Click , to see the large size. ▶ BIG FOTO  

This perfectly synchronized double sequence serves to accurately reposition the next active hour to the nearest hundredth of a second. Too fast for the eye, yet impossible to ignore: “All the cards in the hours game are shuffled and redealt in a hundredth of a second”, as Urwerk’s artistic director and co-founder Martin Frei explains. "The dial transforms before our eyes – so fast that it is barely perceptible to the naked eye. Just beneath the domed glass, the mechanism seems almost within reach – and the Scorpion's sting lurks silently. The satellites nonetheless pivot and regroup at each new hour, escaping our perception by their sheer speed. Each time, there is a brief moment of uncertainty, a slight unease, a silent tension that whispers: perhaps this time, the right number will not appear… And yet the magic happens, instilling a fresh sense of wonder.”

  Click , to see the large size. ▶ BIG FOTO 

This perilous ballet is made possible by two synchronized systems: a cam and rack mechanism inspired by the world of automatons, coupled with a speed governor. Together, they manage power, balance forces and harness energy. 

  Click , to see the large size. ▶ BIG FOTO  

As master watchmaker and Urwerk co-founder Felix Baumgartner explains: “We have pushed mechanical complexity to its limits in pursuit of a single goal: clarity. Each satellite is tilted at 10° to face the wearer. While this complicates everything, the legibility of the time display deserve this level of precision”.

Mechanical alchemy 

The retrograde hand does not simply indicate the time — it literally frames the active hour satellite, from the 0 to 60-minute mark. 

Click , to see the large size. ▶ BIG FOTO  

Once it reaches 60, the retrograde system kicks in, allowing the hand to pounce on the new hour satellite and “disarm” in a flash. 

  Click , to see the large size. ▶ BIG FOTO  

This articulated arm, a high-precision metal skeleton, is governed by a rack and cam performing three functions: defining its trajectory, synchronizing the jumps and multiplying the energy available to power the satellites’ rotation.

  Click , to see the large size. ▶ BIG FOTO   

  Says Felix Baumgartner: “Here, the real complexity doesn’t lie in the number of components, rather in the precision of their interaction. Everything must work in perfect harmony: power, inertia, fluidity. We have designed every spring and every gear train to maximize energy efficiency.”

A bold aesthetic statement

Despite its striking name, the UR-150 Blue Scorpion is an object of elegance and contrast. Its lines are smooth, organic and continuous.

The sapphire crystal follows the shape of the case, which extends seamlessly into a supple rubber strap. The result is an ergonomic timepiece, sculpted for the wrist yet featuring a heart beating with restrained power.
