The New Beast From URWERK: UR-100V T-Rex

The New Beast From URWERK: UR-100V T-Rex

T-Rex is the name of the latest version of Urwerk’s UR-100 collection. It carries both Urwerk’s signature, its satellite hours and that of its namesake in the primal texture of reinforced bronze.

The 41-mm UR-100V T-Rex features satellite wandering hours and a new type of selfwinding system. However, its mosaic of scales, has a somewhat more sensual texture. It’s a watch for those who relish the sensational — and the rare — for only 22 are made.

Its solid bronze case has undergone three successive treatments. The first an unusual composition of the alloy which results in a delicate patina. The bronze is then milled by computer carving the pattern of scales on the top and sides of the case. The final process, sand-blasting and Urwerk’s proprietary method of biochemical burnishing, give the watch its distinctive colour.

The regular orbit of the hours, replicates the planetary dance in miniature. The watch is wound while you wear it by a rotor. This is coupled to a device called the Windfänger that is specific to the UR-100 models. It’s  a planetary gear that limits the action of the rotor to avoid overwinding and excessive wear. 

Finally, the UR-100V T-Rex has a fascinating feature. Once the red pointer of the satellite hours has completed its 60-minute journey, it reappears to show the distance travelled by our planet. In the scale at 9 o’clock on the case the pointer shows the 555.5 km travelled by a point on the equator in a period of 20 minutes. The 20-minute scale on the other side of the dial shows the 35,742 km Earth travels in its orbit around the sun in that time – this is truly ‘out of this world’!
