Tourbillon of tourbillons
Watchmakers are continually striving to perfect the tourbillon, notably by improving its rotation system. The tourbillon is a remarkable technical accomplishment – and a ‘visible’ complication that never ceases to fascinate. This tiny cage, revolving like a planet (in the 18th century, the word ‘tourbillon’ referred to the movement of the stars), also enables the dial to feature a host of geometric and transparent effects.
The new timepiece was conceived, designed and produced by Antoine Preziuso in collaboration with his son Florian. It combines rigour with technical perfection, and is protected by three international patents.
It has been the focus of the reflection and research undertaken by Antoine & Florian Preziuso in recent years. The result: the new Tourbillon of Tourbillons, showcasing a complication that embodies a savoir-faire derived from 35 years of independent watchmaking.
The genius of the design lies in its three tourbillons on a revolving plate, whose combined effect is to grant the watch greater precision whatever the wearer’s position.
The Tourbillon of Tourbillons gravitates and resonates around Antoine Preziuso’s new design.
The hand-winding mechanism of the calibre “AFP-TTR3X” arms a twin-barrel that ensures optimal efficiency and a generous power-reserve. The last wheel and pinion of the going train drive the heart of the system via a central, planetary triple-differential gear which, in turn, drives a revolving plate bearing no fewer than three tourbillons. Each tourbillon is placed at an equal distance from the centre of the plate, with their respective axes forming an equilateral triangle. Each of the three tourbillons completes one rotation around its axis every 60 seconds; it takes just 10 minutes for the revolving plate to complete a revolution with the three tourbillons around the dial.
The foremost factor that guarantees precision: the respective frequencies of the three balances keep step with each other thanks to the resonance achieved by the proximity of the tourbillons. These tourbillons oscillate at a stable frequency.
Five Tourbillon of Tourbillons timepieces will be available in 2015 – with a case version « Power GTS » Gold – Titanium and Steel. The design is light yet robust, with gold support columns and detachable horns in solid 18-ct gold.
The new case is reinforced by 24 ANTOINE PREZIUSO GENEVE’s « Power » screws, and has 45 components tooled in the block, providing utmost solidity and ensuring the timepiece is perfectly waterproof.
The Tourbillon of Tourbillons unquestionably marks a new episode in tourbillon’s history – and one of the most glorious. Apart from the tremendous advances it embodies in terms of innovation and chronometer manufacture, the magical choreography of the three tourbillons on their revolving plate will amaze all who see it.
