Gerald Charles presents the Maestro 9.0 Roman Tourbillon

The exclusive hand-hammered gold novelty introduces a new twist with its pure, uncoated 18K rose-gold dial to the heritage brand’s tourbillon models, while drawing inspiration for its case from Roman architecture and art. This high-end model comes in a limited edition of 50 pieces.


o honour its founder, Mr. Gérald Charles Genta, Gerald Charles is launching the Maestro 9.0 Roman Tourbillon, Ref. GC9.0-A-RT-5N. Mr. Genta originally conceived the Maestro collection in 2005, devising the first ever Maestro case with a tourbillon. Featuring the iconic smile at 6 o’clock, the case has the perfect shape to host the tourbillon cage.

Compared to the previous Maestro 9.0 Tourbillon introduced in 2023 – an understated luxury model, now sold out - the Maestro 9.0 Roman Tourbillon has been revisited with a new twist on the tourbillon embracing an old-style elegance.

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. This special timepiece is not only intended to highlight the brand core values and origins, but also to reinforce Gerald Charles high-end skills and expertise in going beyond the limits.

Behind the realisation of such an intricately crafted and visually stunning dial, lies a work of precision and attention to detail which has become synonymous with Gerald Charles.

The Roman Tourbillon is a high-end model, due to the pure, uncoated 18K rose-gold dial. Fine craftsmanship and comprehensive experience were required to master the art of hand-hammered gold dials. Achieving a balance between the dial craftsmanship, durability, resistance and recreating a consistent finishing pattern were just a few of the challenges the R&D department faced.

The result is a homogenous and refined texture which doesn’t affect readability and 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.

The dial is not the only attribute that stands out, but the watch features two-tone colour and two different materials with a blue titanium bezel on a stainless-steel case, making it an exemplary timepiece. The blue bezel features a specialised coating achieved through an advanced galvanic treatment. Derived from technologies utilised in aeronautics, the process gives the bezel superior mechanical and chemical properties. The coating ensures remarkable durability and resistance to extreme stresses, while the refined blue finish enhances aesthetic appeal and significantly extends the longevity and robustness of the timepiece.

The Maestro 9.0 Roman Tourbillon is an original for Gerald Charles; The first hand-hammered gold dial; the first time two-toned colour and two different material have been used and the first timepiece in the current core collection featuring the hand-stitched blue alligator strap with a brand-new folding clasp.

On a technical level, this new timepiece features a 60-seconds flying tourbillon with the unique skeletonised cage in the shape of the GC logo, returning to the original Maestro flying tourbillon created by Mr. Gérald Charles Genta himself.

To overcome the engineering challenges the tourbillon cage posed, the GC team decided to carve the cage from lightweight Grade 5 Titanium. Despite the difficulty of manipulating this material with the finest tolerances, they managed to reach aesthetic and performance standards, in pursuit of Mr. Genta’s vision of Artistic Creativity and Technical Mastery.

The result is a highly sophisticated 60-seconds flying tourbillon that oscillates at 4hz, made all the more vivid by the natural, three-dimensional contrasts created by combining a surgical-grade stainless steel case, a gold tourbillon bridge and titanium flying tourbillon cage. The screws have been repositioned to hold the 18K yellow-gold bridge to the movement. The timepiece also features a blue indicator applied to the “G” of the cage that serves as a small seconds indicator. A stop-seconds function delivers precise time setting.

The timepiece is 10 ATM/100 mt water-resistant, 5G shock-resistant and offers 50 hour of power reserve, despite the very high technicality.

As with all Gerald Charles watches, it’s the details that set the timepiece apart, from the textured dial to the alligator strap and the skeletonised tourbillon, marking this as an elegant yet sporty timepiece. It represents a Métier d’Art that simultaneously exudes a contemporary and old-style demeanour.
