GCA8000

An automatic caliber featuring a micro-rotor architecture and a celestial-inspired design.

Inspired by the sky

For the Maestro 8.0 Squelette, Gerald Charles engineers developed the automatic calibre with a micro-rotor architecture and bespoke screws exclusive to Gerald Charles. Furthermore, when it came to designing the calibre, it was chosen 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.

SHOCK RESISTANCE

5G shock resistance, tested with 5 axes robotic arm. Incabloc anti-shock system.

A timepiece that truly celebrates the 'art' of the mechanical watch thanks to its open-worked movement.

To combine the Maestro's unique case shape with a skeleton movement undoubtedly presented a challenge.

The movement remains ultra-thin at just 2.6mm high.

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.
