URWERK UR-105 CT Streamliner

Celebrating its 20th anniversary this year, URWERK, the contemporary luxury watch brand established by Martin Frei and Felix Baumgartner presents their new creation, the UR-105 CT Streamliner.

The UR-105 CT is first of all a beautiful object that fits snugly in the palm of your hand. Its unique shape is a remarkable octagon with deep grooves along its length. The Art Deco influences are apparent in its geometric angularity and symmetry.

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 scalefor an analogue and digital display of the time.

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 open-worked 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 self-winding 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 self-winding 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 & mirror-polished steel (CHF 65’000.00 – Swiss francs / tax not included) and Titanium & black PVD coated steel (CHF 65’000.00 – Swiss francs / tax not included).
