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 Intro to Philosophy
Format: Paperback
There’s a lot to this book, if you haven’t read anything by Dostoyevsky before this book could be a little challenging to get into, that being said it was a very good read and a real page turner. There’s some really good stuff in there that is broken down into plain English. Some of the shorter quotes I think were beautiful especially the ones about self reliance and motivations for someone to cling onto religion.

BEYOND GOOD AND EVIL
Format: Paperback
First and foremost: as far as this specific translation of the book goes- I didn't have too much of an issue with it. I will say that whilst reading, I noticed some of the letters were scratched. This will not go against my opinion of the book. At first, I was going place this book in C tier. Only because I couldn't understand it. But after finishing, I will instead put it in A tier. (For me) To start off, I will say to be careful! Only because Neitzsche is (to my understanding) a misunderstood source. With that out of the way, I would like to say that this book did indeed challenge what I believed about "Good" and "Bad." How? Well, Neitzsche has an interesting view on the concept of "Good and Evil" viewing it as "Imposing your will to power onto others and the world around you" By the fourth section, you are given various quotes. Some of those I found myself liking. One of them being: "He who fights with monsters mustn't become one. The longer you gaze into the abyss, it gazes also into you" For me to understand what was said here, I feel as if I should look more into Neitzsche (as far as this review is concerned at the moment) Final score: 4.5/5

Provoking philosophical work
Format: Paperback
A challenging and thought‑provoking philosophical work that explores morality, individuality, and human nature. Deep and insightful, though dense and not an easy read.
