Enquire About This Product

T for Tarantula has a fully open sapphire crystal display revealing the satellite hours. 

The avant-garde design has stood the test of time and is just as relevant today as it was ten years ago when it first launched. The 18k 5N red gold gives a regal look with a blend of warm tones reflecting off the different lines and depth of the case.

The Tarantula gets its name from the spider-like four split legs which hold the orbiting satellite carousel, which slowly creeps across the dial from zero to sixty. For the first time fully exposed thanks to the large domed sapphire crystal.

Inside the UFO looking timepiece is a manual wind calibre 3.04, with a 36-hour power reserve. Turn the 103T over, to reveal our iconic control board displaying: power reserve indicator, 15-minute and seconds dials for precise time-setting and user-adjustable fine-tuning screw.

Limited to only 60 pieces on its original launch, we now offer the chance to purchase one of our classic UR-103T in red gold again. In nearly new condition, fully refurbished and tested by our own watchmakers. Complete with a two-year Pre-Owned warranty, new Blatimora textile and leather strap, and URWERK box.

This is currently ready for Pre-Order and will be ready for delivery in the first week of April.

Creators Thoughts:

Felix Baumgartner - “We like strange-dangerous animals, 202 Hammerhead, T-Rex, the 103 Tarantula and the carousel really looks like one!

When we presented this watch at the four seasons in Geneva, and an official guy from the zoo came every night to look after the real spider we exhibited;)"

Martin Frei - “With the UR-103 T we opened the 103 cases totally. Therefore I had to redesign the merely technical revolving hour satellite Mechanism. I added an element, the Tarantula, that keeps/ holds the hour satellites and at the same time partially covers those hour numbers not used while the actual hour is indicated."

Condition Rating UR-1: As new, with no or very few signs of wear, the movement is serviced and in working condition.
