Urwerk's latest mechanical opus unquestionably warrants its place among the brand's "Special Projects". Proudly descended from the UR-CC1 King Cobra, it displays minutes in two ways – retrograde linear on a central cylinder and progressive digital on a cone –, jumping digital hours on a second cone to the left of the linear minutes, and digital seconds on the top of the case. In a world-first, these seconds are brought into visual range, across a central window, by optical fibres. Another new experience lies with the crown, now a fluted cylinder integrated into the top of the case that's rolled to wind the movement. The time is set by swinging a lever from the side of the case then turning the roller forwards or backwards. Proposed as two limited editions of 25 each, in polished steel or steel with a gunmetal finish.
