Tourbillon 24 Secondes
144 pieces (2007-2017) | White gold | Red gold | PlatinumWith the inclined Tourbillon 24 Secondes, Greubel Forsey capitalizes upon the speed of rotation and the inclination of the regulator to harness the influence of gravity on the regulating organ. Enabling the moving parts to cover a major distance in a short space of time and to perform a complete rotation in just 24 seconds called for the implementation of innovative solutions including a specially constructed inclined gear profile.
The use of extremely low-density alloys stemming from the aeronautical and aerospace industries facilitated the creation of a unique and ultralight Tourbillon system inclined at a 25˚ angle, perfectly suited to the powerful stresses imposed by the speed and in particular by the cage advancing in steps which are two and a half times greater than in conventional Tourbillon systems.
The construction of this calibre has off-centered the Tourbillon 24 Secondes system, a technical option that provided scope to define an original case and dial architecture characterized by a well-balanced asymmetry. The latter serves to ensure ideal visual access to the mechanism and to the various items of information.
Invention
Tourbillon 24 SecondesThe Tourbillon 24 Secondes uses a fast rotation speed and inclined angle to solve the problem of critical positions of the oscillator in relation to gravity. The 25˚ angle and the rapid rotation of the tourbillon cage significantly improve the chronometric performance of a system containing only one tourbillon, especially in stable positions. Consequently, we had to develop an inclined gearing profile and an ultra-light tourbillon cage to resolve the considerable mechanical constraints imposed by this system.
