The tourbillon mechanism of the "Tourbillon 24 Secondes", inclined at a 25 degree angle, appears magically detached from the gear train, as it completes its high-speed rotation in 24 seconds.  The rotating cage is composed of 88 parts weighing 0.39 grams.  The use of extremely low-density alloys such as Avional and titanium, employed in the aeronautical and aerospace industries, enables the tourbillon carriage to overcome the huge stresses imposed by the high rotation velocity. 

Characteristic of Greubel Forsey creations, the case construction affords the wearer exceptional views of the tourbillon system.  The sapphire crystal in the band and the dial opening enable the viewer to admire the extreme angular velocity of the cage.  This exceptional platinum timepiece is numbered 1, making it especially rare and prestigious for serious collectors of independent watch maker's timepieces.
