URWERK UR-103T Tarantula

18k White Gold Satellite Time

Overview

Some watches become classics the moment they appear. The URWERK UR-103T Tarantula is one of them.

Crafted in 18k white gold, the UR-103T reveals its mechanical architecture through a large domed sapphire crystal that exposes the satellite hour system beneath. The open design transforms the display into a kinetic sculpture, allowing the four orbiting satellites to move across the dial in full view.

When introduced, the UR-103T pushed URWERK’s design language further than ever before. Today the watch remains just as futuristic and compelling as when it first appeared, a piece of mechanical design that continues to define the early era of the brand.

The white gold case adds a refined presence that moves effortlessly between casual and formal settings, equally at home with relaxed clothing or formal attire.

Case and Design

The UR-103T, known as the Tarantula, features one of the most visually distinctive interpretations of URWERK’s satellite time display.

Its fully open dial construction exposes the satellite carousel beneath the sapphire crystal. The structure supporting the satellites resembles the form of a spider, giving the watch its Tarantula nickname.

Large domed sapphire allows an unobstructed view of the revolving mechanism while reinforcing the architectural nature of the design.

Satellite Time Display

Time is displayed through URWERK’s signature revolving satellite hour system.

Four hour satellites rotate across the dial, each carrying the hour numerals. As the carousel moves, the active satellite travels along the minute track to indicate the time. The open Tarantula structure partially covers the inactive hour discs while revealing the active hour as it moves through the minute arc.

The result is a display that feels both mechanical and organic, constantly shifting as the satellites orbit across the dial.

Movement

Inside the UR-103T beats the URWERK calibre 3.04, a manually wound movement developed for the UR-103 family.

The movement provides a 36 hour power reserve and drives the complex satellite display through a sophisticated carousel mechanism.

Like all early URWERK pieces, the movement architecture reflects the brand’s experimental spirit and focus on alternative ways of displaying time.

The Control Board

Turning the watch over reveals one of the defining elements of the UR-103 series.

The URWERK Control Board presents several functional displays designed for precise monitoring and adjustment of the movement.

The case back includes:

• power reserve indicator
• running seconds
• 15 minute counter for precise time setting
• user adjustable fine tuning screw

This system allows the wearer to monitor the performance of the watch and make small regulation adjustments when required.

Creator Thoughts

Felix Baumgartner

“We like strange and dangerous animals. The 202 Hammerhead, T Rex, and the 103 Tarantula. The carousel really looks like one.

When we presented this watch at the Four Seasons in Geneva an official from the zoo came every night to look after the real spider we exhibited.”

Martin Frei

“With the UR-103 T we opened the case completely. I had to redesign the technical revolving satellite system.

I added the Tarantula structure which holds the hour satellites and partially covers the hour numerals that are not being displayed.”

Good idea great product
Color: Gloss Black
I bought this as a gift. The person loves it. It’s very compact. She puts it in her bag and travels with it. It’s easy because you can charge it at home and then it’s already. She sometimes brings her charger with her so she can use it out.

Works great.
Color: Gloss Black
We preferred this model because the button is on top of the unit, making it easier to use. And we do use it often. The battery lasts for a reasonable amount of time too, and charges quickly on USB.

Great Product - Stop Wasting Batteries!
Color: Gloss Black
Super happy with this purchase and so glad it's rechargeable. So much better than the fancy brand we had that went through batteries like crazy and had a wobbly shaft. Lots of power and can be easily used for travel as we do for blending protein powder and cream into coffee. It's already traveled to Europe twice, Tahiti, Australia and a Panama cruise and still working like the day we got it. We're very pleased with the quality and the price.

Frothing like a barista!
Color: Gloss Black
Works great! It took some practice to produce froth without the coffee splattering! But, once I got the hang of it, the results were amazing!
