URWERK UR-101 Diamond Sky

Diamond-set Satellite Watch – A horological vision under a starry sky

With the UR-101 Diamond Sky, URWERK unveils a rare creation that blends contemporary haute horlogerie with the art of jewelry. Produced in a limited edition of 25 pieces, this exceptional watch reinterprets one of the brand’s seminal models through a resolutely modern and luminous approach.

A reimagined watchmaking icon

Much more than a reissue, the UR-101 Diamond Sky embodies a natural evolution of URWERK’s DNA. Inspired by the first models unveiled in 1997, it revisits the codes that revolutionized time display: a 180-degree satellite display, where the hour glides from left to right, like the sun’s path.

This mechanical signature, now iconic, is reimagined here within a new aesthetic where light plays a central role.

A diamond-set watch conceived as a celestial map

The 41mm steel case transforms into a veritable cosmic landscape. Its surface, finely engraved with a geometric pattern, evokes an abstract constellation in which each diamond acts as a luminous marker.

Far from a mere decorative exercise, the gem-setting is fully integrated into the watch’s structure: The contrast between the steel and the diamonds enhances visual readability and gives this UR-101 a unique presence, both technical and precious.

• each stone marks a point of balance
• each reflection accompanies the passage of time
• each angle captures and diffuses light

The satellite display, a signature of the URWERK house

At the heart of this creation, the satellite system embodies the brand’s entire philosophy: to offer a different, dynamic, almost narrative way of reading time.

Conceived as a trajectory, the display transforms the hour into continuous motion. This approach, developed by Felix Baumgartner and elevated by Martin Frei’s design, remains one of the most distinctive signatures of independent watchmaking today.

A limited-edition collector’s watch

Produced in a limited run of just 25 pieces, the UR-101 Diamond Sky is aimed at collectors seeking a rare, conceptual, and profoundly unique timepiece.

It does not seek to follow trends, but to forge its own path:

a watch where time becomes a trajectory,

where the material captures light,

and where every detail tells a story.
