rex is the royal highness of all dinosaurs, and the most iconic dinosaur of them all. Completely enmeshed in contemporary culture and the scientific community, this carnivorous lizard roamed the earth for over 2 million years.

With over 50 percent original bone material and mounted in a dynamic, scientifically accurate and modern pose, the 67-million-year-old TRX-293 TRINITY is among the finest known unearthed specimens of one of the largest terrestrial predators that ever ruled our planet. The bone material consists of three exceptional Tyrannosaurus specimens that were unearthed between 2008 and 2013.

TRINITY is the highlight from the Out of This World auction by Koller in Zurich – and it is accompanied by 75 exciting objects including one of the largest Mars meteorites on earth, a space suit that was used on international space missions, original movie props from Batman, The Excorcist, Alien and a huge gold nugget.

Among them is Urwerk’s UR-105M Trinity T. rex watch, a pièce unique born from the space-time collision between the TRX- 293 Trinity dinosaur and the most contemporary of measuring instruments. “We created this unique timepiece by respecting the characteristics of the TRX-293 TRINITY. Our timepiece has been worked to match the dinosaur, both in relief and colour‘,” said Felix Baumgartner, master watchmaker and co-founder of Urwerk about the ribbed and scaly bronze case and oxidized bezel with an earthy and ageless look.

An estimated 65 million years stare back at the observer through a sapphire crystal inserted into the caseback of this unique mechanical watch, where DNA from the TRX-293 TRINITY‘s skeleton has become an integral, ever-present part of the timepiece.

“The imposing presence of the T. rex meets and mingles with the fragile mechanical ticking of our T. rex, the two echoing and complementing each other,” explains Martin Frei, artistic director and co-founder of Urwerk.

Technically speaking, the UR-105M Trinity T. rex is a satellite-hour watch such as only Urwerk makes. Four satellites each bearing three hours numerals successively parade along the minutes rail. The subtle ingenuity of the mechanism lies in this invisible carousel fitted beneath the satellite structure and responsible for the smooth, silent operation of the satellite hours.

TRINITY can be viewed in the spectacular foyer of Tonhalle Zurich next to the Lake Zurich until April 16. The auction will take place on April 18. Click here for more information.
