In 18k white gold, set with over 24 carats of baguette-cut sapphires plus three solitaire trillion sapphires on the dial, this unique piece is powered by the brand’s signature Tourbillon of Tourbillons movement.

Three international patents protect the TTR3 Blue Equalizer Frequencies. reflecting the creativity and capacity for innovation of Antoine Preziuso Genève, where the project was brought to fruition after a decade of research. Associating three tourbillons on a revolving plate gives the timepiece unmatched regularity, thanks to its triple differential. 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.

This differential is unique both in its conception and the variety of tasks it performs. It must distribute constant energy from the double-barrel to the three tourbillons through the centre of the watch, without affecting the axis of the hands; react if one the tourbillon stops working; and correct any variations in frequency. It contains the tiniest ball-bearing in the world, barely 1.6mm in diameter!

The closeness of the three independent regulating tourbillons – and their positions on the plate – enable 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.
