Urwerk unveils a new model in its SpaceTime Collection called the UR-100 GunMetal.

A journey around the sun

The new Urwerk UR-100 GunMetal displays our journey around the sun each day, a subject that has long fascinated the brand. Urwerk even takes its name from the ancient city of Ur in Mesopotamia where the Sumerians were the first civilization to divide the day’s sun and shadows into 12 parts, creating the first recording of time. Today we have the most sophisticated tools to measure the time, but our days are still governed by the light of this celestial body.

Distance traveled around the sun

The UR-100 GunMetal measures two fascinating statistics. The first is the distance we travel in 20 minutes if we are standing on the equator of our rotating planet, and the second is the journey through space around the sun…35,740 km every 20 minutes. These fun facts are eye-opening and a reminder of the enormity of the galaxies beyond our own planet.

Galactic display

The hours and minutes are indicated by the brand’s trademark satellite configuration and come in vivid green, while the kilometer measurements are displayed in a bright white. The timepiece comes in titanium and stainless steel with a gunmetal PVD finish. The dimensions of the case are width 41mm, length 49.7mm and height 14mm.

The UR-100’s caliber 12.01

The Urwerk UR-100 is powered by the automatic caliber 12.01 with a 48-hour power reserve. The movement drives the carousel carrying the hours on three satellites. These satellites travel in succession along a 60-minute scale. Each one is made from anodized aluminum that is sanded and shot-blasted. The caliber’s bi-directional rotor is governed by a profiled airscrew called a Windfänger.

Nostalgic look

Urwerk fans will notice some similarities with the brand’s early models. As Martin Frei, the brand’s co-founder and designer explains: “We have adopted some of the stylistic features of our first constructions, and then deconstructed them. For example, the steel dome of our early models is now in transparent sapphire crystal. The hard outlines of the titanium case highlight its perfection. Because I’m always at odds with the dictates of symmetry, I have used different proportions to catch the eye.”

The Brand


On December 31st, 1995, Martin Frei organized a New Year party for students in a squat in Lucerne. He had invited his friend Christoph Draeger, who brought his cousin, Felix Baumgartner, a watchmaking apprentice. Shortly before midnight, the party was in full swing, with everyone dancing and shouting. However, Martin and Felix had found each other and were in a deep philosophical conversation about time and its perception.
