The Maestro 9.0 Tourbillon Gem-Set Sapphires is a Limited Edition of 10 pieces, based on the Maison's first ultra-thin skeleton watch. The gem-set watch is themed around sapphires, 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, while the vulcanised rubber strap matches the colour of the precious gem.

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

Anglages diamond polished. Radial côtes de Genève finished bridge of the tourbillon. Yellow gold colour engravings.
