TTR3 Blue Equalizer Frequencies – The new creation of Antoine Preziuso

Reading Time: 4 minutes

With his excellent reputation for watchmaking craft, Antoine Preziuso is proud to present his new creation TTR3 Blue Equalizer Frequencies. This unique watch in 18 ct white gold contains 233 saphirs of over 24 ct in total, in rare blue royal, baguette-cut, invisible mounting, with three solitary trillion saphirs floating on the dial, beside the three tourbillons. The Tourbillon of Tourbillons movement, a core component for this brand, is the result of a collaboration between him and his son Florian that is at the heart of this brilliant watch.

Unmatched regularity thanks to its triple differential. AFP-TTR-3X – The Power of Three

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.

Multiple Tourbillons on a Revolving Plate

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.

Triple-Differential or Synchronizer

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 3 Hz.

The case

The generously sized 47 mm case has a sapphire back that allows the beholder to admire all the beauty and complexity of the patented movement, with three tourbillons to the front connected by a triple-differential gear rotating around each other in 60 seconds while the plate completes six rotations each hour.

Unique piece


Tradition, complications, innovation: these three words underpin the work of Antoine Preziuso, founder of the brand ANTOINE PREZIUSO GENÈVE, which in 2018 celebrates thirty-eight years of independent watchmaking. From his studies at Geneva’s Ecole d’Horlogerie – where he discovered his calling – to the creation of the Tourbillon of Tourbillons (in close collaboration with his son Florian), Antoine Preziuso has always been inspired by three powerful values: respect for watchmaking tradition; mastery of major complications; and a constant quest for innovation in technique and design. It was Antoine Preziuso, for instance, who conceived the first watch entirely in meteorite: case, dial, buckle and hands in 2002.

Antoine Preziuso was born in Geneva, in prime watchmaking territory, but is also proud of his Italian roots. His twin origins help explain the identity of his timepieces, with irreproachable technical quality allied to the striking design. He swiftly became a passionate restorer of old timepieces, attracted by the savoir-faire of master-watchmakers of the past, and by the attention they lavished on the quality of finish. His respect for watchmaking tradition finds concrete expression in the watches he designs. The very first watch made by ANTOINE PREZIUSO GENÈVE, back in 1991, already bore the Geneva hallmark!

Antoine Preziuso is internationally recognized for his mastery of major complications, which connoisseurs can admire under his own name or in his regular work for other brands. His workshop produces minute-repeaters and perpetual calendar watches, although it is above all the Tourbillon that dominates his attention: a complication combining elegance, technique and poetry that has reigned supreme in the art of watchmaking for over two hundred years. The Tourbillon’s fascination lies in the number and size of its components and the movement of its cage, which recalls the movement of the stars. The Tourbillon is also the favoured means for Antoine Preziuso to continuously improve the chronometric quality of his timepieces.

ANTOINE PREZIUSO GENÈVE is a family business. The passion for watchmaking, the love of uniqueness, of the luxury of good manufacturing that comes only from time and experience are values that Antoine Preziuso claims and shares with his family members. May, his wife, has always been at his side. She is a source of undying support, in all aspects of life, not unlike a watchmaking calibre component; her role could be compared to that of a bridge. Solid and reliable. Or, perhaps better yet, to that of a differential, harmonizing as best as possible the forces and equilibriums within this extraordinary family. Laura, their daughter, expressing her talent by combining jewellery and watchmaking techniques in a mechanical jewellery collection. She is also teaching at the Geneva School of Applied Art. Florian, their son, has followed Antoine’s path. That of watchmaking and its technical difficulties that haunt you until you solve them. He is now closely involved in all the company’s new designs, and masters every aspect of R&D and production.
