The Préciplus -- everyman's knock-about, high-performance flying tourbillon, manual or automatic, with a fast-beat balance, 72 to 96 hours of power reserve off twin barrels, is around a fifth of the price of the classic Lémania tourbillon."The Breguet-style tourbillon costs too much, it's too fragile and there's too much inertia," explains Mr. Gschwind. "A conventional tourbillon watch retails from USD50,000 to more than 300,000. Our tourbillons can be retailed in the USD15,000 to 30,000 price range -- the same as chronographs, perpetual calendars and jewelry watches. There are around 500,000 watches sold each year in that price category."
Progress Watch is able to provide brands with Préciplus tourbillon movements from around USD3500, by reducing the number of parts to 38 from the 70 to 130 components of a conventional tourbillon.
Options on the 31mm (13 1/2 lignes) caliber include manual wind (5.4mm high, 23 jewels) or automatic (6.4mm, 26 jewels), as well as an analogue date ring at 12 o'clock, corrected by a push-piece.
Double shock-absorbers of a new design and a robust, simplified construction make the Préciplus shock-resistant enough for sports watches. But it's a construction that demands the highest manufacturing precision. The tourbillon's fixed wheel, for example, is machined to tolerances of one micron. The high-frequency balance (28,800 v/h) is unique in a tourbillon and arguably gives it an edge in precision over the conventional 21,600 v/h devices. The movements are homologated by Chronofiable, and protected by a battery of patents.
