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.
In the Streamliner, Felix Baumgartner and Martin Frei take you to the New York of their youth, a plunge into a city of different facets, from the top of the highest skyscraper to the depths of the subway.
