Gerald Charles

Maestro 8.0 Squelette


The Maestro 8.0 Squelette features a stoned grey vulcanized rubber strap, which perfectly matches the 18K Rose Gold 4N Maestro case, and sandblasted bridges polished with anglage and anthracite-NAC finishes. In order to ensure an higher legibility of the open-worked movement, the 4N Gold coloured and polished baton shaped hands are more squared and larger than in other watches of the Maestro Collection. Furthermore, the hands are filled with white Super-LumiNova, while the minute-track is in poudré Rose Gold 4N.

GCA 5482 automatic open-worked caliber

For the Maestro 8.0 Squelette, Gerald Charles engineers develop the automatic Ref. GCA 5482 calibre, with a micro-rotor architecture and bespoke screws which is exclusive to Gerald Charles and which has been specifically designed so that it can be enhanced with various complications. When it came to designing the GCA 5482 calibre, Mr. Octavio Garcia chose the theme of the celestial sky chart. The star-shaped cage that holds the micro-rotor in place is shaped like a shooting star, with rays spreading playfully across it.

8.35mm ultra-thin watch

The Maestro 8.0 Squelette has been engineered with a bespoke gasket to seal the case's sapphire crystals and the screw-down crown, ensuring a 10 ATM water-resistance. Furthermore, the case, the lugs and the pin buckle are all on the same straight line. Hence, the adhering surface on the wrist is maximised to well distribute the timepiece's weight, enabling to wear it everytime and everywhere.
