With the first glance you drop at the Urwerk UR103T, your attention is caught by the rotating satellites featuring the hours. The original satellites take turns gliding past the minute arc. The watch indicates the hours digitally and the minutes analogically.
Creators of the Urwerk watch wanted to ensure the ideal balance of the rotating satellites that are about 300 times heavier than a conventional hand. One more challenge was to minimize friction, thus preventing the energy waste.
Keeping these two challenges in mind, Felix Baumgartner, master watchmaker and co-founder of Urwerk, opted for aluminum for the satellites as this material is characterized by remarkable strength and lightness.
Each satellite is found on a bronze/beryllium Geneva cross and suspended from an orbital cross structure produced from ARCAP 40, a material highly appreciated for its lightness, corrosion-resistance and non-magnetic qualities.
Each satellite features three hour numbers. The satellites performs a full revolution of the dial every 4 hours and in that period of time turn four times 120°, to rotate 480° on their own axis. Each hour number shows the time as it moves slowly across the minute track featured across the lower part of case.
The back of the Urwerk UR103T reveals the brand’s unique world premier ‘Control Board’. This is a true dashboard for a wristwatch, crafted from titanium. The Control Board demonstrates a 43-hour power reserve indicator, 15-minute and seconds dials for precise time-setting, as well as fine-tuning screws for adjusting the movement.
The three-dimensional case of the Urwerk UR103T is crafted in red gold or grey gold. It accommodates a manual-winding movement - Calibre 3.03. The movement provides 43 hours of power reserve. The timepiece is presented on an alligator leather strap.
Watches.InfoNIAC.com thinks it is remarkable that the heart of the timepiece is actually inspired by arachnids and "T" in the name of the watch stands for Tarantula.
