The brand new UR-100 V IRON is here! One piece of the 25 limits is now available on the official URWERK-STORE.

Stripped back to the bare essentials: with a steel and titanium case, a monochrome look achieved with delicate finishing all done by hand. A combination of circular graining and sanding shot peening; chamfered screw heads and mirror polishing.

“The main reason to fall in love with a watch is an emotional reaction to its looks,” declares Martin Frei, URWERK’s chief designer and co-founder. “Beyond the complexity of its mechanism, we have tried to refine this watch as much as possible. The UR-100V IRON appears in all its naked glory, leaving only the light reflecting on the metal to reveal its beauty.”

Time Travel
In addition to URWERK’s trademark satellite configuration of the wandering hours and minutes, the UR-100V IRON brings your spin through space into sharp focus. When the minute's hand has completed its 60-minute journey, it reappears on a 20-minute scale of 555 kilometres. This is the distance you travel in 20 minutes if you are standing on the equator of our rotating planet. The opposite scale tracks your journey through space around the sun: 35,740km every 20 minutes.
In the display on the UR-100V Iron, time and distance are on a par, the hours and minutes in blue, and the kilometres in bright white.

Watchmaker and URWERK’s co-founder, Felix Baumgartner, reveals that he got the idea from a clock given to him by his father, Geri, a noted restorer of antique clocks. “It was made by Gustave Sandoz for the Universal Exhibition of 1893. Instead of showing the time, it showed the distance travelled by a point on the equator.”

Under the Dome
URWERK’s new calibre 12.02 drives the carousel carrying the wandering hours on three satellites. This new movement enabled a redesign of the carousel, bringing the hours closer to the minutes as they travel in succession along the 60-minute scale. The result is an easier and more intuitive reading of the time. This carousel, as well as the structure on top of the hours, are forged from anodised aluminium then sanded and shot-blasted, while the satellite screws are each circular sanded. The satellites rest on a carousel of sanded brass plated in ruthenium. The structure on top of the hours display is in sanded and shot-blasted aluminium. The self-winding rotor of the UR-100 is governed by a profiled airscrew known as the Windfänger.

A touch of colour 
The UR-100V IRON wears a blue Alcantara strap, matching the blue of the numerals and markers. After the sunlight fades, the blue display shines with a bright blue SuperLumiNova. With the space-time indications in green.

For Felix Baumgartner, the 100V IRON sums up tradition and simplicity. He feels, "The finishings; satinée, polishing, micro sandblasting all of which are executed in-house by hand by one trained URWERK employee, this to me embodies tradition. Simplicity comes from the time pared-back time display. We moved the hour numbers as close as possible to the minute dial, this enables extreme intuitive time reading."

Many owners of URWERK watches will recall our early models. The UR-100 carries their DNA, adopting some of the stylistic elements and deconstructed them.

Martin Frei explains “For example, the steel dome of our early models is now in transparent sapphire crystal. The hard outlines of the titanium and steel case highlight its perfection. Because I’m always at odds with the dictates of symmetry, I have used different proportions to catch the eye,”
