This Antoine Preziuso Trillion Tourbillon of Tourbillons, a masterful homage to the challenges of watchmaking, features three tourbillons dancing on a revolving plate, which are connected by a triple-differential gear and separated by three pure-white Top Wesselton G+ trillion diamonds. The three tourbillons rotate around each other in 60 seconds and the plate completes six rotations each hour. At the back of the watch, on bridges decorated with Geneva stripes, there are three rubies on the sapphire back that are positioned at six o’clock, opposite from three other smaller rubies at twelve o’clock. The complex architecture of this watch, which is set off by a 47mm case that is deliberately extravagant, blends harmoniously with the white 18ct gold with 233 diamonds that are 24 carat baguette-cut in rare white (Top Wesselton G+), invisible mounting, of unparalleled purity and radiance.
Associating three tourbillons on a revolving plate gives the timepiece unmatched regularity. Each tourbillon completes one rotation per minute, at a faster rhythm than the plate, which completes six rotations per hour (one rotation every ten minutes). The speed at which the tourbillons rotate is accelerated by this double revolution. They are placed equidistant from the centre of the plate, with their respective axes forming an equilateral triangle. Isochronism is enhanced by the fact that the three cages rotate on different axes and at variable speeds. The closeness of the three independent regulating tourbillons – and their positions on the plate – enables them to resonate, and naturally adopt an identical frequency through a phenomenon known as “synchronism”. When the tourbillons start to resonate, their amplitude increases significantly – in a manner perceptible to the naked eye. The system as a whole thus forms a single revolutionary regulator, vibrating at a perfectly stable frequency of 3Hz.
