Gerald Charles Maestro 9.0 Tourbillon is a limited edition masterpiece, with only 50 pieces available. This technical and aesthetic marvel is the result of a year and a half of meticulous research and development, paying tribute to the original design of the Maison's founder, Mr. Gérald Charles Genta. The distinctive "smile" at 6 o'clock in the Maestro case is a perfect fit for the tourbillon cage, adding a touch of natural elegance.
