The Maestro 3.0
The Maestro 3.0 Chronograph in stainless steel features an emerald green sunburst dial and the iconic indexes and peculiar hands shape, filled with Super-LumiNova®, directly coming from Mr. Gérald Charles Genta’s original drawings.


Movement
For the GC3.0-A Chronograph, Gerald Charles returned to the Calibre Ref. GCA3022/12, an automatic chronograph movement based on the GCA3002. It too offers remarkable thinness, measuring just 6.07mm in height, including its bi-directional rotating oscillating weight, and also offers a twin-barrelled 50-hour power reserve. It showcases the best of fine Swiss tradition enriched by Côte de Genève decorated bridges. Gerald Charles’s watchmakers worked to maximise the movement’s accuracy and 50-hour power reserve, and to improve vibration and shock resistance.
The Maestro case 3.0
For the Maestro 3.0 Chronograph, Gerald Charles has once more revisited the iconic Maestro case. With an overall 40mm fit, it has been subtly but significantly updated with more squared angles. The bespoke chronograph pushers were never seen before and the overall form has been designed to sit flat on the wrist, measuring only 11.5mm in depth.


Water-resistance
The watch has been engineered with a bespoke gasket to seal the irregularly shaped sapphire crystal. Extensive tests have been conducted in the world’s deepest indoor pool built in 2014, thanks to the collaboration of our Friend and European champion in the 100m freestyle, Luca Dotto, who dove in apnea wearing the GC watches.

Green Emerald
The Gerald Charles strap in emerald green features its classic double-face decoration with Clou de Paris on one side and the GC logo’s tapisserie on the other. This is also an original design by Mr. Genta for the Swiss Maison. The strap material is a technical vulcanized rubber, chosen by the Maison to guarantee superior water resistance, strength, durability and comfort on wrist.
