URWERK goes into summery mood with the new UR-105 TA “Black Orange” and “Black Lemon” models.

“The first technicolor UR-105 TA watches are ready,” declares Felix Baumgartner, URWERK’s co-founder and master watchmaker. “For years black has been URWERK’s signature colour. Now we’re overturning our principles. We want you to take a fresh look at our watches, beyond the engineering and the finish. We want to trigger that primal impulse, love at first sight with colours that hit you in the eye.”

The “Black Orange” and the “Black Lemon” are part of the new UR-105 TA collection presented earlier this year at Baselworld. The TA in the name stands for “Turbine Automatic”, a spectacular approach to automatic movements developed by URWERK. The automatic winding is optimally regulated by dual air turbines on full show on the back, and this is not all. The wearer can chose between three winding modes, using a small lever: in “Full” position the slightest movement will wind the mainspring, on “Red.” (for Reduced) the winding is moderated to minimize excessive tension on the mainspring, and finally, on “Stop” the winding system is disabled the watch can be hand-wound using 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.”

The dial of the UR-105 TA looks familiar following the same four satellite layouts as previous URWERK models. 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. Upmost care is given to the finishing of the tiniest details, 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.

Felix Baumgartner about the invisible carousel responsible for the operation of the satellite hours : “With our previous timepieces, our satellites were supported by an orbital cross at the top. We rethought this concept and made some refinements. The fruits of this can now be felt when setting the time on the UR-105 TA: There is virtually no friction, no jerking movement, just the ballet of satellites. It is the fluidity of the gears that quietly reveals all our hard work”.

Here in North America, you can the URWERK UR-105 TA collection at Westime in Los Angeles and it will be probably priced north of US$60,000.

As a graphic designer, I'm fascinated by the crossroads between technology and aesthetics. Horology is one of these crafts, where art and engineering come together to produce mechanical wonders that grace the eye. WatchPaper was born from the desire to create an online tool where I can share my passion for watches.
