Case

An homage to the Maestro flying tourbillon created in 2005 by Mr. Gérald Charles Genta

The Maestro 9.0 Tourbillon case is crafted in medical-grade stainless steel and hosts a 60-seconds flying tourbillon cage in titanium in the shape of the Maison’s GC logo. The flying tourbillon is a complication dear to our Maison, as the Maestro case’s signature “smile” at 6 o’clock was originally conceived to host the Tourbillon’s cage.
