The Tourbillon 24 Secondes Incliné (T24Si) is Greubel Forsey's third fundamental invention and continues the exploration into minimising the effects of gravity on the regulating organ. This is achieved in the T24Si by means of an innovative tourbillon cage undergoing rapidly changing positions with a high angular velocity.
Mastering the high velocity of the T24Si's single carriage required breakthroughs in both materials and design. The laboratory determined that Avional and titanium offered the ideal mechanical properties necessary in minimising the higher energy consumption and stresses of the faster rotating tourbillon: Avional for the pillars of the tourbillon cage and titanium for the carriage bridges. The 88 parts of the T24Si system weighs a mere 0.39 grams.
The development of a complex inclined gearing for the satellite pinion, combined with an ultra-light tourbillon cage, has delivered a system perfectly suited to the powerful stresses imposed by the high velocity. Testing shows that the T24Si's approach significantly improves the performance of the single-axis tourbillon.
