Maestro 9.0 Roman Tourbillon

LIMITED EDITION OF 50 PIECES The Roman Tourbillon is a 50-piece limited edition collection in celebration of the Roman architecture and art from which the iconic Maestro case inspiration comes from; amply emphasised by the roman numerals on the dial.

Métier d’Art: Hand-hammered 18K, rose-gold dial

The watch features a pure, uncoated 18K rose-gold dial. The finishing of the dial makes each piece extremely unique and exclusive. Given the technique and handmade craftsmanship only two pieces per month can be produced. The buyer of a Roman Tourbillon’s will own a truly unique piece as no one watch is identical to another. 

Movement: Flying tourbillon Ref. GCA 3024/12

The Maestro 9.0 Roman 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.

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

The Maestro 9.0 Roman 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.
