+ | ====== Greubel Forsey GMT Quadruple Tourbillon ====== | ||
+ | {{wst> | ||
+ | |||
+ | **GMT Quadruple Tourbillon** is a luxury wristwatch from [[Greubel Forsey]]. | ||
+ | |||
+ | New edition of the previous model in white gold, this time (February [[2021]]) in titanium case and with sporty design. Although products of the highest rank are to be expected from the brand anyway, this model also represents a top performance within the in-house range. | ||
+ | |||
+ | The | ||
+ | Quadruple Tourbillon is Greubel Forsey’s second | ||
+ | Fundamental Invention, The mission: to average | ||
+ | out positional errors due to gravity in all situations, | ||
+ | especially in stable wristwatch positions. | ||
+ | To achieve this, the original tourbillon has been | ||
+ | elevated to realise its full potential: inclined at | ||
+ | 30°, doubled and then quadrupled. The result, | ||
+ | two synchronised Double Tourbillon 30° mechanisms, | ||
+ | where a first cage, inclined at 30° and | ||
+ | rotating in one minute, is nested within a second | ||
+ | horizontal cage, completing a full rotation in four | ||
+ | minutes. A spherical differential transmits the | ||
+ | average timing rate of the four tourbillon cages, | ||
+ | improving the overall chronometric performance | ||
+ | of all the regulating organs. | ||
+ | |||
+ | Planet Earth, set near eight o’clock, shines in a | ||
+ | new light with the blue livery. An original Greubel | ||
+ | Forsey creation from ten years ago (2011), the | ||
+ | rotating terrestrial globe allows for the simultaneous | ||
+ | display of several different time zones: on the dial side, with a 24-hour ring around the | ||
+ | Earth, for Day/Night indication and on the caseback side, displaying 24 major cities their | ||
+ | respective time zones while distinguishing between those which use summer time (on a | ||
+ | light coloured backdrop), and those which do not (on a dark backdrop). | ||
+ | |||
+ | The sapphire crystal window around the equator completes the timepiece, offering a complete | ||
+ | view of the Earth in motion, with its continents immersed in the deep blue ocean waters, complementing the exquisite blue finish of the power reserve, hour circle and strap. | ||
