The UR-105 CT: Urwerk in a New York state of mind
Urwerk is 20 years old. A time to look back over our shoulder, not with nostalgia or regret, but to recapture a sense of excitement. It was 20 years ago that 22-year-old Felix Baumgartner set foot in New York, where Martin Frei had made his home. It was vibrant, noisy and thrilling, a giant playground of fantasy and tension. Today they evoke that mix of emotions in their new creation, the UR-105 CT Streamliner.
In March 1997, Martin Frei graduated from the College of Arts and Design in Lucerne (Switzerland), and moved to New York where he joined other Swiss artists in founding the United Swiss Artists (USA) association. He was then living in Brooklyn — in a garret that soon became a creative hub. Felix was in Geneva, Martin across the Atlantic. Their brainchild, Urwerk, had been born but was struggling to take its first steps. The UR-101 and UR-102 were critically acclaimed but the company wasn’t viable. Its founders just managed to keep it above water amid increasing misgivings. What did the future hold for Urwerk? Should they persist with a dream that was eating up all their savings? With these questions in mind, Felix took a plane to New York to join his friend. Felix Baumgartner was 22, Martin slightly older.
“the Streamliner has a minimalist design with few frills and clean lines. In the initial drawings, I thought of the Empire State, the Chrysler and the Comcast buildings. That is why it has that vertical structure that seems to go on forever.” – Martin Frei
You have to slide the catch on the top of the case to reveal the mechanism of the UR-105 CT. It’s a new wandering hour indication based on an openwork carousel, which carries the four satellites, each bearing three numerals for the hours. The hours successively sweep past the minutes scale for an analogue and digital display of the time. According to Felix Baumgartner, Streamliner is an apt name for this watch. “The UR-105 CT is a watch with a flexible design. When it is closed, it looks austere, with only the time indication visible. Open the protective cover and you delve into a metallic environment that is quite cold, yet you perceive a notion of speed and an effort at efficiency. The Streamliner’s carousel has been completely redesigned, becoming lighter, stronger and far more effective.”
A power-reserve indicator and digital seconds make up the rest of the information displayed on the dial. The digital seconds are remarkable in that they indicate tens of seconds. The mechanism was made using a photolithographic process, with each marker openworked to make it as light as possible. It thus weighs less than a tenth of a gram. Two pneumatic turbines on the back govern the selfwinding rate, which can be set with a lever. In the full position, the slightest movement of the wrist is harnessed to rewind the barrel spring. Turn the lever to stop to disengage the selfwinding system and wind up the UR-105 using the crown. An intermediate position, red (for reduced) engages the turbines to dampen the winding rotor and avoid overstressing the mainspring, if you are particularly active.
The Streamliner comes in two versions:  Titanium and mirror-polished steel (CHF 65’000.00 – Swiss francs / tax not included), and  Titanium and black PVD coated steel (CHF 65’000.00 – Swiss francs / tax not included)
