The Maestro 9.0 Tourbillon Gem-Set Diamonds is a Limited Edition of 10 pieces, based on the Maison's first ultra-thin skeleton watch. The gem-set watch is themed around diamonds, and features 66 baguette-cut stones of the highest purity set by hand into an 18K white gold bezel by specialist gem-setter Salanitro Geneve. The case is in medical grade stainless steel.

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. 

Sertissage Made in Geneva: PRECIOUS STONES SET BY HAND

Complex engineering solutions have been applied to integrate a series of precious gems into the Maestro’s curved case architecture. The challenge is brought up by the irregular shape of the bezel which requires a special cut for each precious stone.

Movement: Flying tourbillon Ref. GCA 3024/12

The Maestro 9.0 Tourbillon is powered by the automatic flying tourbillon caliber, Ref. GCA 3024/12. This exclusive manufacture movement features bespoke bridge designs decorated with a special vertical Côtes de Genève pattern inspired by tailoring, thanks to Mr. Genta’s Italian heritage. Anglages diamond polished. Radial côtes de Genève finished bridge of the tourbillon. Yellow gold colour engravings. Gerald Charles’ team succeeded in realizing a highly sophisticated 60-seconds flying tourbillon that oscillates at 4 Hz and in delivering a highly technical mechanical watch that remains incredibly slim, measuring just 9mm thick.
