Linear operation : On the UR-CC1, there are two horizontal indications displayed by two cylinders: one for the (jumping) hours and a retrograde cylinder for the minutes.
The seconds are displayed by a rotating disk on the dial.
The UR-CC1 is the result of more than three years of research, development, production and testing to ensure that the rotation and instant fly-back of the large hour and minute cylinders was achieved without compromising accurate timekeeping.

Triple-cam : The triple-cam is crafted from bronze beryllium, a metal selected for its inherently self-lubricating properties and low co-efficient of friction, and takes the form of three small inclines. The precise shape of the curve of the incline is relayed to the pivoting rack, while the teeth on the end of the rack mesh with and rotate the minute cylinder.
The triple-cam makes a complete rotation in three hours so that each of the three inclines takes 60 minutes, and 180 points of reference have been calculated on each of the three cams to ensure the precise and isochronic rotation of the minute cylinder.

Rack : The toothed segment at the end of the rack transmits and transforms the rotation triple-cam into the rotation of the minute cylinder. The toothed rack presents two properties that at first appear contradictory: absolute rigidity, so as to accurately transmit the motion of the cam to the minute cylinder; and extremely low mass to consume as little energy as possible and minimise the effects of gravity and accelerations/shocks.
The rack has been fabricated in silicon by Mimotec using their photolithography process. The honeycomb pattern of the silicon structure resolves the two apparently contradictory requirements of maximum strength and minimum weight.

Seconds Ring : The dial is animated by a rotating disk displaying the seconds, both digitally and linearly – a world first. This incredible exploit was achieved thanks to Mimotec’s photolithography production technique, which enabled an ultra-light high-precision component.
To reduce mass to an absolute minimum, the minuscule numerals were even skeletonised. A small tab at 10 seconds bearing the URWERK logo precisely counterbalances the disk's single-digit numbers. This marvel of micro-precision weighs only 0.09 grams, and that includes the SuperLumiNova.

Rotor Fly Brake : The pneumatic shock-absorbing Rotor Fly Brake automatic winding system minimizes rotor and mechanism wear and damage from shock and harsh movements. The operation of the Rotor Fly Brake is visible through a window on the side of the case.
