The Tourbillon 24 Secon🐠des is Greubel Forsey's third invention incorporating a movement that is truly mesmerizing to view in action. The tourbillon is inclined at a 25° angle and performs a 24-second revolution, a remarkable feat when compared to more traditional one-minute tourbillons. The Tourbillon 24 Seconds Incline works to minimize the effects of gravity on the watch; the use of extremely low density alloys such as Avional and titanium, which are employed in aeronautics, enables the tourbillon carriage to overcome the stresses imposed by the high rotation velocity. The tourbillon cage alone comprises 87 parts, yet it weighs just 0.39 grams.

The superior hand finishing of𝓀 Greubel Forsey’s movements is renowned and practiced with acute attention, as a quarter of the team at the firm’s atelier is purely devoted to this work. The architecturally inspired case, with its asymmetrical design, is perfectly balanced by the opposing niches that contain the tourbillon carriage and the power reserve sector. With an additional curved sapphire crystal set to the side of the case, it is possible to fully appreciate the tourbillon carriage in action, as it gives the impression of being almost magically detached from the gear train.

The present lot in platinumꦆ is distinguished by the visually stunning three-dimensionality of it's dial architecture. The off-set subsidiary dials, layered chapter rings, and inscribed panels are harmoniously arranged in anthracite, creating an aesthetic that is dynamওic, powerful, and legible.
