Enquire About This Product

Initially launched in 2016 as a limited edition of 22 pieces. The T-Rex gets its name from its bronze suit of armour. The atypical case is crisscrossed by a raised, concentrically ribbed pattern evoking reptilian scales –  textured and tactile, that is soft to the touch. The colours of this breastplate subtly evolve over the years with wear as the bronze oxidizes. Each model is treated as one-of-a-kind. It is decorated, bead-blasted, micro-sandblasted, purified and then oxidized by hand with a brush.

Four satellites, each bearing three-hour numerals, successively parade past the minute rail. This original and intuitive reading of time is facilitated by a cover made of PEEK (polyetheretherketone) that conceals satellites that are irrelevant to the current time. This cover is adorned with a superb guilloché pattern in keeping with the finest watchmaking traditions.

The visible satellite on the dial plays a decisive role by focusing our attention on the moment. The past no longer exists, and the future has yet to be created. All that counts is the time being displayed. What will we do with these 60 minutes?

The caseback shows the turbines of the UR-105 T-Rex, which regulate the watch's winding. They are adjusted utilizing a lever. In the "FULL" position, even the slightest movement is leveraged to help wind up the mainspring. The UR-105 T-Rex is thus in automatic winding mode; the effect of its turbines optimizes the winding. In "STOP" mode, the winding system is disabled, and the UR-105 can thus be hand-wound if required via the crown. A third intermediate, "RED" (for REDUCED), moderates the winding to avoid excessive tension on the mainspring.

The UR-105 T-Rex was one of the most popular iterations of the 105 family. Its unique engraved case in bronze blends the past with a modern design, making it an absolute URWERK collector favourite. Now available in our Certified Pre-Owned collection, in near-perfect condition. Backed by our two-year international warranty and comes with a new Baltimora technical fabric strap and an original URWERK box.

Creators Thoughts:

Felix Baumgartner - "This 105 model also embodies the year of research invested into URWERK's wandering hour satellites. The ingenuity of the mechanism lies in the invisible carousel fitted beneath the satellite structure and is responsible for the silent and smooth operation of the satellite hours. In previous models, our satellites were fitted on a Maltese cross and 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. There is virtually no friction, no jerking, just the ballet of the satellites. The fluidity of the gears quietly reveals our hard work."

Martin Frei - "The UR-105 T-Rex represents the symbiosis of two dimensions, time and space. The means chosen to indicate the time is ancient, inherited from the Sumerians and dating back to the second millennium BC when the shadow cast by the sun playing across their imposing monuments served as their clock. It is nonetheless truly contemporary. Today, the position of our satellite on the dial plays a decisive role by focusing our attention on the moment at hand. The past no longer exists, and the future has yet to be created. All that counts is the time being displayed. What will we do with these 60 minutes?"
