    The Maestro GC 8.0 Squelette

    The new Maestro 8.0 Squelette is a watch that combines Mr. Genta’s unmistakable Maestro case shape with an extraordinary and unique open-worked movement that truly celebrates the 'art' of the mechanical watch. This new and unique in-house manufacture ultra-thin automatic movement has been developed with Vaucher Manufacture Fleurier exclusively for Gerald Charles, under the creative direction of the contemporary watch designer Mr. Octavio Garcia. The case of the Maestro GC 8.0 Squelette is based on the Maestro 2.0 Ultra-Thin model, and it has been slimmed down to 8.35mm, to enhance the watch’s ergonomics further and push elegance and performance to their limits. As with every Gerald Charles watch, a screw-down crown ensures the Maestro 8.0 Squelette is water-resistant to an impressive 100 metres.


    Hand drawn, hand crafted

    To successfully combine the Maestro's unique case shape with a skeleton movement undoubtedly presented a challenge, both in terms of aesthetics and the practicalities of production - a fact that made it all the more important to call upon Garcia's experience in bringing the project to fruition. The design process involved hundreds of iterations, all of which drawn by hand, that was essential in order to fully explore all the possibilities.


    A new and unique movement

    The great designer Octavio Garcia worked hand-in-hand with Vaucher Manufacture Fleurier to develop the automatic Ref. GCA 5482 calibre, which is exclusive to Gerald Charles and which has been specifically designed so that it can be enhanced with various complications. The design process of the Maestro 8.0 Squelette involved hundreds of iterations, in order to fully explore all the possibilities.

    Ultra thin, intricately finished, fully robust

    While it comprises 160 components, the movement remains ultra-thin at just 2.6mm high and incorporates an exquisite, star-shaped gold micro rotor running on ceramic bearings in order to allow as much of the mechanism as possible to be on display. And, despite its slimness, the Maestro 8.0 Squelette offers a power reserve of an impressive 50 hours. On the dial side, the skeletonised bridges are satin-finished and rhodium plated or anthracite NAC treated, while all angles, bevels and apertures are hand-polished and all wheels circular-grained on each surface. The rehaut (the inner ring between the dial and crystal) is retained by a series of nine, star-shaped screws that were designed and developed specifically for Gerald Charles. The distinctive Maestro case in which the movement is showcased is equally complex, comprising no fewer than 18 separate components and a screw-down crown that, as with every Gerald Charles watch, ensures the Maestro 8.0 Squelette is water resistant down to an impressive 100 metres - a feature complemented by the clous de Paris patterned rubber strap.
