Urwerk’s UR-105 T-Rex is a perfect example of the brand’s sense of humour. The company has clad its UR-105 with a case crisscrossed by a raised, concentrically ribbed pattern, suggesting a reptile’s scales. This textured, bark-like coating is soft to the touch, and its colours will adapt their own patina over the years.
Technically speaking, the UR-105 T-Rex is a satellite hours watch such as only Urwerk makes them. 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 the satellites not relevant to the time read-off. In keeping with the finest watchmaking traditions, this cover is adorned with a superb guilloché pattern.
The back shows the turbines of the UR-105 T-Rex which regulate the winding of the watch. They are adjusted by means of 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 and its winding is optimized by the effect of its turbines. 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 so as to avoid excessive tension on the mainspring.
