As explained by HH, "The concept was a technical tour de force, requiring the combined efforts of three of watchmaking’s most renowned engineers. The arrangement of parts was inconceivably unorthodox - it has essentially no true case! The crystal and the bezel are actually part of the movement; the Freak has no crown, no hands and the movement pivoted to indicate time."
And most recently, Ulysse Nardin developed the 'InnoVision' Freak (below). Improving breakthroughs with more extensive use of the light flexible material silicium throughout the movement and 96 non-lubricated ball bearings guide the barrel both vertically and laterally, in fact, the entire watch is now oil/coating/lubrication free.

The Freak is the brainchild of Dr. Ludwig Oechslin, as interpreted by Ulysse Nardin's research and production team. "The Freak" is a tourbillon of 7-day duration, without hands or winding crown. In most tourbillons, the balance wheel assembly rotates once per minute in a cage. In the "Freak", the whole movement rotates once per hour, the drive wheel meshing with teeth around the whole circumference of the dial, a similar arrangement mounted below driving the hour wheel. The mainspring is located underneath the movement and spans the entire diameter of the case. The extra large size of the mainspring provides the watch with a power reserve of one week. Winding is accomplished by turning the back of the case anticlockwise. The “Dual Direct Escapement” invented by Dr. Ludwig Oechslin, astronomer, mathematician and master watchmaker. Among his many inventions for Ulysse Nardin are the "Perpetual Ludwig" and the "Trilogy" of astronomical wristwatches. The “Dual Direct Escapement” consists of 2 impulse wheels transmitting the energy directly to the balance wheel; they each rotate in the same direction and connect alternately with the balance. Using the technology of the CSEM (Centre Suisse d'Electronique et de Microtechnique), the 2 wheels at the center of the “Dual Direct Escapement” are plasma-engraved out of single-crystal silicon, the material from which computer chips are made. This technique offers the greatest hardness coupled with low weight."
