URWERK reinvents its iconic satellite hours complication.  The UR-150 Scorpion appears in a rounded shell, with a lightning sting triggered in a hundredth of a second.  Inspired by the arachnid’s stinger, the nickname of this creation references the trajectory of the 240-degree minutes sector, resembling a scorpion’s tail poised to attack. This symbolism also extends to the retrograde minutes hand, ready to unleash its blistering power as it strikes each passing hour.

This UR-150 features a large open worked hand framing the prevailing hour.  Once the 60th minute has elapsed, the hours hand jumps to zero and the journey begins anew. At the same time, all the satellite hours spin on their axes and the retrograde hand frames a new hour – all in just 1/100th of a second.  As the hour hand reaches ’60’, an URWERK spring triggers the UR-150’s lightning-fast attack: the retrograde hand makes a 240° jump and the hour satellites simultaneously rotates 270°. “It’s like a perfect alignment of the stars, a perfect storm”, says Felix Baumgartner.

“In order to drive all the satellites, guide the hour hand and ensure that each element jumps at just the right time, we have designed a new satellite complication system.  We have therefore replaced our ‘classic’ device based on Maltese crosses with this cam and a rack system.  To make this burst of movement more visible, we have doubled the usual distance between the 60 and 0 markers”, he concludes. 

The minutes display on the UR-150 is more expansive, moving from the usual 120 degrees to a 240° arc.  The retrograde system is the most ambitious ever undertaken by URWERK. The automatic winding system is among several innovative features found on the UR-150. Inside this new body, URWERK has installed the latest evolution of its wandering satellite-hour movement.
