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.
