The Maestro GC 8.0 size guide

The new elegant and performing timepiece

Embodying Gerald Charles’s philosophy, the Maestro 8.0 Squelette continues the heritage of the Maison: an elegant and audacious aesthetic, immediately recognisable thanks to the iconic Maestro case and the vulcanised rubber strap.

Thanks to the intensive teamwork between engineers, technical team and R&D department, the result is an elegant yet highly technical timepiece.

The Art of the mechanical watch

The GC8.0-RG-06 is an automatic skeleton timepiece, which celebrates the art of the mechanical watch. It took two years of research and development to combine design and technical performance to produce the first Gerald Charles bespoke open-worked calibre.

For the first time ever Gerald Charles introduces the rubber strap in a Stoned Grey colour, which perfectly matches the 18K Rose Gold 4N Maestro case, while the sandblasted bridges are polished with anglage and anthracite-NAC finishes.

The decentred micro-rotor as a beating heart

The bespoke calibre GCA 5482 is powered by a decentred micro-rotor in 22K Rose Gold 4N with a double-face finishing featuring colimaçon on one side, and our “honeycomb” motif on the other.

Thanks to the insertion of the micro-rotor, the movement thickness has been reduced to just 2.6mm, making the Maestro 8.0 Squelette the thinnest timepiece in Gerald Charles collection, with an overall thickness of 8.35mm.

It offers a 50-hour power reserve thanks to the single barrel, visible between 1 and 2 o’clock, and has a 5G shock-resistance measured on 5 different axis thanks to the robotic arm test.

Water-resistance, ergonomics and readability

The Maestro 8.0 Squelette has been engineered with a bespoke gasket to seal the sapphire crystal and a screw-down crown decorated with a Clous de Paris motif, ensuring a 10 ATM water-resistance.

The case, the bezel, 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 weight, enabling to wear it every time and everywhere.

Finally, to ensure the legibility of the open-worked movement, the 4N Gold coloured and polished baton shaped hands are more squared and larger than the other Maestro Core Collection watches and filled with white Super-LumiNova®, while the minute-track is in poudré Rose Gold 4N.
