Lot Essay

With the Tourbillon 24 Secondes Incliné, Greubel Forsey's third fundamental invention, the house 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 ultra- light 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 the Calibre GF01 has off-centred the Tourbillon 24 Secondes Incliné 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.

The present "Tourbillon 24 Secondes Incliné" timepiece is preserved in excellent overall.
