This model, the 'Freak' defies the conventions of mechanical wristwatches, as it features non-traditional mechanics for setting and winding and functions without a standard crown or standard hands. With this model, Ulysse Nardin introduced two new innovations to the watch making world, the 7-day power-reserve Karrusel movement and the dual-direct escapement. With an enlarged mainspring spanning the entire diameter of the case, the watch is able to run for 7 days while the movement rotates once every hour. The dual-direct escapement is composed of two wheels made of silicon that allow the mechanism to transmit energy efficiently without lubrication. The Karussel movement was invented in 1894 by Bahne Bonniksen, differing from Abraham Louis Breguet's Tourbillon because it allowed the entire escapement to revolve within the watch once in 52½ minutes in most cases, while being supported only at one end, whereas the tourbillon revolves once every minute and is suspended in a cage by two ends.
