Maestro 3.0 Chronograph Black

The GC3.0 Chronograph in steel represents another significant evolution of the Maison’s signature Maestro model. Following its premiere in 18k rose gold, it is now available in steel for the first time. Featuring a new hand-finished manufacture chronograph calibre, the new GC3.0 in steel weights 110gr.

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.
