In the model’s retrograde mechanism, a flying carousel bearing the three hour satellites follows a route determined by a cam. The latter orchestrates the motion of the carousel, a performance that lasts precisely 60 minutes. 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°.

Insights
New satellite complication system based around a flying wheel and pinion positioned between the satellites and the base movement.
We have therefore replaced our ‘classic’ device based on Maltese crosses…
…. with this cam and a rack system.
This necessitated developing a spring so special that we needed to machine it in our own workshop.

“The scorpion is a nasty beast – yet the design of the UR-150 is gentle. It’s very URWERK … the aggressive symbolism belies the reality of the watch’s cool, calm personality”
