The UR-105 TA (TA for Turbine Automatic) isn't round, has no hands, and no tourbillon: It is 100% pure URWERK. It is the watch that the team had the most fun in designing, the most pleasure in developing its mechanisms, and the most satisfaction in its hand finishing and assembly. The UR-105 TA is a real watchmaker's watch that explodes with creativity with a palette of zesty colors thanks to URWERK’s unconventional chief designer Martin Frei.
URWERK presents the UR-105 TA a.k.a. the "URWERK Knights".
The UR-105 TA revisits URWERK's iconic satellite indication, which has been an emblematic and instantly recognizable signature element of the brand for 18 years. Four satellites, each bearing three hour numerals, successively reveal themselves from under a sublime guilloche black cover in PEEK (polyetheretherketone) as they parade past the minute rail to display the time. Everything exudes precision and refinement, from the carrousel chassis to the dial, from the touches that are invisible to those on full display through the large sapphire crystal. For example, the hidden ARCAP satellite carrousel has been treated with ruthenium then micro bead blasted to a finish meeting the very highest standards of haute horlogerie.
The “TA” of the UR-105 TA stands for “Turbine Automatic”. That is because the movement’s automatic winding is optimally regulated by dual air turbines on full show on the back. These turbines are bead-blasted, satin-finished and treated with black PVD for perfect aesthetics. The winding mode is selected by a small lever.
In the “FULL” position, only the slightest movement is needed to wind up the mainspring. "RED." (for “REDUCED”) moderates the winding so as to minimize excessive tension on the mainspring. On "STOP" mode, the winding system is disabled and the UR-105 TA can then be hand-wound if necessary by the crown.
“The UR-105 TA is our URWERK Knight,” says Martin Frei, artistic director and co-founder of URWERK. “The bezel evokes the breastplate of a knight’s armor, protecting the mechanism from the ravages of time. The UR-105 TA is an haute horlogerie creation, with all high-end codes respected, but in the Black Orange or Black Lemon versions, it's their zesty appeal that really arouses the senses.”
