URWERK reaches for the stars with the UR-102 “Gaïa”

Geneva, May 30th 2021

It is an iconic model, jealously safeguarded until now at the heart of the watch Maison, since it marks the beginning of the URWERK adventure in the 1990s. The foundation stone. A watch of almost disconcerting simplicity, with a wandering hour as its only marker of time. The UR-102. This one-of-a-kind model in asphalt-coloured anodised aluminium with a platinum caseback has been newly enhanced with a midnight blue lacquer. It will be auctioned on 6 November 2021 on behalf of the "Only Watch" charity to fund research into Duchenne muscular dystrophy.

This unique piece embodies the wild aspirations of a team composed young dreamers who had only just graduated – from the School of Arts for Martin Frei and from the Solothurn Watchmaking School for Felix Baumgartner and his brother. In 1997, they set out to conquer the world, armed with a brilliant idea and modest capital. Their first watch, the UR-102, was presented at the Baselworld watch fair on the booth of the AHCI (Académie Horlogère des Créateurs Indépendants). This model ran resolutely counter to existing and generated a certain amount of controversy at the time its launch. It is now the symbol of victorious pugnacity, of salutary stubbornness. What a destiny!

"We have chosen to name this model ‘Gaïa’. We recently had the immense honour of receiving the Gaïa Prize* for Entrepreneurship from our peers. This award recognises a journey from oblivion to the limelight, along with tenacity, conviction and pugnacity that have repeatedly been put to the test. This model reflects this fierce determination that blazes new trails. We dedicate this symbol of hope to all those who struggle to make things happen”, said URWEK co-founders Felix Baumgartner and Martin Frei.

This UR-102 is unique in many ways. It is undoubtedly one of the first watch creations to honour a mixed-genre approach merging the common metal aluminium with the nobility of platinum.

Its full, round shape is seamlessly smooth. Framed by precious platinum, the caseback features an interpretation of the Gaïa prize, a dazzling flight of fancy symbolising URWERK’s unswerving resolve to reach for the stars.

The UR-105 Kryptonite

The team from URWERK are back with a fun new model, the UR-105 Kryptonite.

And for once, I was very pleased to receive a press release that was not chuck-full of hyperbolic language, but rather told a cool story.  And in this case, I do not feel I could do it more justice than the original, so here it is in their own words -
 
“It’s one of the stories my horologist father told me as a child,” recounts watchmaker Felix Baumgartner the brand’s co-founder. “He was fascinated by the stories associated with the historical timepieces he restored. According to the legend, the Pope ordered a special clock from the Campani brothers. It had to tell the time in the dark when he celebrated the divine offices at night. But the clock had to be silent so as not to disturb the Pope when he slept, while the time had to be immediately visible. The Campani brothers produced the so-called “wandering hour” clock in which the hands were replaced by hour numerals that successively traversed a scale of 60 minutes. The passing hours were illuminated from within the clock by a candle. Needless to say, many of these clocks, made largely of wood, caught fire, and the system fell into disuse, but one survivor was sent to my father for restoration. I found it fascinating.”

Thus one of the fundamental requirements of every URWERK watch is to show the time clearly in the dark. “I enjoy the idea of fulfilling the Pope’s specifications,” says Martin Frei, URWERK’s co-founder and chief designer. “By preserving its original DNA, we have kept the concept alive.”

URWERK's Mechanical "Smart Watch" - the EMC

Since its inception in 1997, URWERK have made their mark in the world of haute horlogerie with innovative displays and indications, in particular their signature satellite complications. In parallel with this, the watchmaking team has always taken pleasure in exploring new avenues and meeting new challenges.

The UR‑210 - More than the Sum of its Parts

Ever wonder what's in a watch?  Well, in so far as Urwerk's UR-210, wonder no more!

This assemblage of goodies comes together to form this -

So here are the details straight from Urwerk -
The dial of the UR-210 features a traditional power reserve indication at one o’clock. In a near mirror image at 11 o’clock we find a similar indication. No, it isn’t a duplicate fail-safe, but something much more important which deserves our full attention, because it is actually a world-first complication that
indicates winding efficiency over the last two hours.



When you are comfortably nestled in your armchair, the indicator will be tending towards the red zone to tell you that your UR-210 is not being wound enough by its automatic rotor and is running on stored energy. However, if you are moving around energetically, the indicator will point towards the green zone, a sign that you are replenishing your watch with new energy. This entirely new indication does not measure mainspring torque, but calculates the difference between the consumed and generated energy of the mainspring.

Armed with knowledge of both winding efficiency and available power reserve, you are now able to intervene. If your UR-210 indicates an insufficient supply of energy, you can position the winding efficiency selector (at the back of the watch) to “FULL”.

The rotor will then convert the slightest movement into stored energy. In this configuration, a turbine connected to the rotor provides smooth, unimpeded power. But if you are more active, then that may provide more power than required and unnecessarily wear the mechanism. In that case, you would position the winding efficiency selector to “REDUCED” to engage the rotor damping system. An air turbine compressor mounted on ruby bearings ​​spins and creates internal resistance – enough friction to slow down or dampen the automatic winding rotor. In “STOP” mode, the automatic winding system is disabled completely and the UR-210 runs off reserve power and may require manual
winding.

Back to the dial side, the UR-210’s satellite complication with retrograde minute is both highly original and totally explosive. The principal feature is a high-tech, oversized, three-dimensional retrograde minute hand. Its function is to enclose the hour satellite and indicate the time as it transverses the 0-to-60-minute scale. This one-hour journey through time, tracing an arc of 120°, is smooth and fluid. But the true nature of the piece is revealed at the end of the 59th minute. Then a sharp distinct “click” signals the return of the minute hand to its starting point. In less than 0.1 of a second the hand flies back to dock with the next hour satellite. This lightning fast retrograde system is based on three key elements:

·       A central axis set in ruby bearings provides excellent stability for the satellite/retrograde complication. A cylindrical marine chronometer type spring runs vertically around the axis and generates the optimal tension required for the retrograde minutes flyback.

·       A minute hand, which also forms a frame for the hour satellites, displays the time in an extraordinary way. Milled from aluminum to exacting tolerances of approximately 3 microns, the whole structure has a total weight of just 0.302g and is counter balanced by a brass weight. This three-dimensional cage offers rigidity as it transfers energy from the cylindrical flyback spring in the top center of the carrousel to the double-star gear underneath.

A double coaxial star-shaped cam regulates the retrograde mechanism through its gearing and its rotation defines the trajectory of the minute hand. When the minute hand reaches 60, the double star trips a (one of three) hockey-stick shaped spring under the mechanism, which liberates the minute to fly back to the next hour satellite at 0-minutes.
