Freak 28'800 V/H: The Evolved Freak [2005] The Freak 28'800 V/h, commonly known as the second generation, was launched in 2005 with an upgraded escapement called the Dual Ulysse Escapement.
The new escapement has 18 identical teeth, with hooked tips resembling shark's teeth, nestled on the edge of the improved detent instead of the first generation's 25 teeth per escape wheel, 5 of which extend to match the The brake is engaged. Since all teeth are now functionally touching the bung, the scan angle per scale is reduced and the mechanism is therefore more stable. Since it takes less time to rotate at a smaller angle, the new movement can accommodate high-frequency balance, thus increasing from 3Hz to 4Hz, or 28,800vph, which is where the model name comes from.
In addition, the circular balance was also replaced by a free-sprung balance with four adjusting screws recessed into its periphery and a silicon balance spring. In addition to the escapement, the Freak 28'800 V/h also introduces a locking plate to prevent accidental turning of the bezel.
Freak Diamond Heart 28'800 V/H: Experimental Freaks [2005] 2005 also saw the introduction of the experimental Freak Diamond Heart 28'800 V/h, introducing the first escape wheel and hairspring etched from synthetic diamonds by DRIE. Synthetic diamond has the same desirable properties as silicon, namely low density and a low coefficient of friction, but is harder than silicon, making it more durable. The parts are produced by GFD (Gesellschaft für Diamantprodukte mbH) in Germany, which specializes in growing synthetic diamonds using chemical vapor deposition. However, mass production proved impossible due to high costs.
Subsequently, Ulysse Nardin began a joint venture with Mimotec in 2006 to form Sigatec, a manufacturer specializing in silicon parts DRIE and metal parts LIGA (Lithographie, Galvanoformung, Abformung), enabling them to produce lightweight precision parts. , corrosion resistant and non-magnetic on an industrial scale and make it available to other sectors of the industry.
