The Maitre Cabinotier retrograde armillary tourbillon model was produced by the three master watchmakers who created Ref. 57260 -the most complicatedtissot watches replicaever made, unveiled final September. It contains two of the complicated characteristics with the superwatch: the armillary tourbillon along with the double retrograde indication.

The retrograde function governs the hours and minutes although the tourbillon revolves on two axes and features a spherical balance-spring.

Double retrograde system

The manually wound calibre 1990 motion developed and manufactured by Vacheron Constantin capabilities retrograde hours and minutes indications with instant flyback. The hands flick back to zero at such a velocity the special attention is needed to ensure a precise indication and such lightweight and resistant resources because the titanium made use of within the hands.

Armillary tourbillon

The elegantly structured armillary tourbillon operates as asphere perpetually rotating on two axes under a sapphire crystal dome at 9 o'clock. It is known as an armillary tourbillon because it is based mostly on an armillary sphere just like the one incorporated in an astronomic clock made by the French clockmaker, Antide Janvier, while in the 18th century. The spherical balance spring, which was very first developed by Jacques-Frederic Houriet in 1814, is notably unusual in today's longines watches for sale. The shape ensures the concentric development of the spring and consequently the isochronism with the balance wheel. The tourbillon carriage, produced of lightweight aluminium alloy, incorporates Vacheron Constantin's Maltese Cross emblem, which forms up each 15 seconds as the tourbillon rotates. This ongoing spectacle may well be admired every 30 seconds through a sapphire crystal opening over the side with the case.

High-precision motion

The armillary tourbillon achieves remarkable timekeeping precision. It truly is fitted that has a new form of escapement, developed and made by Vacheron Constantin which has the escape wheel and lever in silicon with diamond pallet stones for resistance to wear and prolonged life. The escapement, made as lightweight as possible through the use of high-tech products, contributes significantly to your efficiency of this observe, which greatly exceeds the requirements of your Swiss Official Chronometer Testing Institute (COSC).

Contemporary styling and finish

A different function that can make the Maitre Cabinotier retrograde armillary tourbillon observe unique could be the modern styling applied to the architecture and finish of your movement. The calibre 1990 is electro-plated with an NAC treatment in a dark anthracite colour creating a mirror-polished impact.

On the dial side the movement displays its modern architecture with sharply reduce bridges tempered by a sunburst satin finish and Geneva stripes. The back presents a more conventional look, finished with Geneva stripes. The painstaking do the job of chamfering all the edges took a lot more than 130 hours.

The indications are shown on two dials that partially cover the baseplate so as to reveal the outlines and contemporary finish with the motion. On the right, the retrograde minutes and hours hands describe a semicircle above 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 the silvered disc. The tudor watches for saleare exceptionally also engraved around the dial side over the inscription "Armillary Tourbillon".
