Prestigious Swiss watch manufacture Vacheron Constantin unveils Maître Cabinotier retrograde armillary tourbillon, a unique type of watch that takes up the two original complications of the most complicated watch ever made, the Ref. 57260 that incorporates 57 complications.
The Maître Cabinotier retrograde armillary tourbillon model timepiece bearing the Hallmark of Geneva was produced by the three master watchmakers who created Ref. 57260. In this brand new wristwatch, the manufacture has incorporated two of the complicated features of the superwatch: the armillary tourbillon and the double retrograde indication. Its contemporary styling opens the remarkable structure of the calibre 1990 movement to view. The high-precision manually wound movement is housed in a 45.7mm case in white gold. Four patent applications have been filed for this unique model.
The Maître Cabinotier retrograde armillary tourbillon model is the first born of this project. It’s a remake of two of the Ref. 57260’s complications, the double retrograde indications and the armillary tourbillon, in a contemporary guise. The retrograde function governs the hours and minutes while the tourbillon revolves on two axes and has a spherical balance-spring. The movement coated with NAC (a special metal alloy) is also revealed through lateral windows in its imposing case. This timepiece forms part of the select Maître Cabinotier collection, which showcases Vacheron Constantin’s horological achievements, customised work and overall excellence.
Another feature that makes the Maître Cabinotier retrograde armillary tourbillon watch original is the modern styling applied to the architecture and finish of the movement. The calibre 1990 is electro-plated with an NAC treatment in a dark anthracite colour creating a mirror-polished effect. On the dial side the movement displays its modern architecture with sharply cut bridges tempered by a sunburst satin finish and Geneva stripes.
On the right, the retrograde minutes and hours hands describe a semicircle over a sunburst satin finish punctuated by applied white-gold hour markers and a black minutes scale. Placed symmetrically, the tourbillon carriage carries the seconds pointer around a scale on a silvered disc. The Poinçon de Genève hallmark is exceptionally also engraved on the dial side above the inscription “Armillary Tourbillon” to certify the supreme quality of this timepiece.
Four patents are pending for the calibre 1990 inventive features:
1. The instantaneous retrograde system: The minutes cam alone determines when the hands for the minutes and the hours fly back. The retrograde action of both hands is thus synchronised at noon and at midnight.
2. The collet: The collet fixing the spring to the balance staff is made in lightweight titanium to improve the isochronism of the balance. Titanium’s weight and volume match those of the other materials in the regulating organ, making the collet ideal for use in a tourbillon.
3. The multi-carriage tourbillon: The tourbillion is made up of two carriages, one inside the other. As they rotate they form a Maltese Cross every 15 seconds. The tourbillon has a Vacheron escapement and sprung balance. The escape wheel is made of silicon with a diamond-like coating, while the diamond pallet stones have a very low coefficient of friction.
4. The lever: The silicon lever can be fitted with movable pallet stones so that the watchmaker can adjust them as in a conventional pallet lever. The diamond coating of the lever makes it stronger and more resistant to wear, while the friction between the fork and impulse pin is markedly reduced.
