 +
 +**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.
