Launched in 2017 as the final iteration of Greubel Forsey’s Tourbillon 24 Secondes series, the Asymétrique Edition Historique is a horological farewell executed with the brand’s signature finesse and uncompromising detail. To commemorate the close of this landmark series—first introduced in 2007—Greubel Forsey produced just 22 examples of the Edition Historique: 11 in platinum and 11 in 5N red gold. The present watch, numbered 170/183, is the 170th piece within the entire production of the Tourbillon 24 Secondes series, and one of the 11 produced in red gold.

At its heart beats the hand-wound Caliber GF01, comprising 280 components and featuring Greubel Forsey’s pioneering inclined 24-second tourbillon, set at a 25° angle. The faster rotation and inclined axis work in concert to improve timekeeping performance by minimizing gravitational errors in more positions than a conventional tourbillon.

The 44mm red gold case is immaculately finished, from the mirror-polished bevels to the frosted plates, and is fitted with a domed sapphire crystal that offers a panoramic view of the inclined tourbillon.
As a coda to one of Greubel Forsey’s most technically ambitious and aesthetically daring series, the Tourbillon 24 Secondes Asymétrique Edition Historique represents not just an exceptional timepiece, but a landmark in contemporary independent watchmaking—imbued with vision, invention, and extraordinary craft. Offered in extremely well-preserved condition and accompanied by its full set of accessories, this remarkable timepiece encapsulates the best of modern fine watchmaking.
