Gerald Charles

Maestro 2.0 Ultra-Thin


The watch's emerald green sunburst dial and vulcanised rubber strap, featuring the Clous de Paris motif on the top side and GC's logo tapisserie on the other, fully match the stainless steel of the Maestro case and the polished pin buckle with brushed applied plate and GC logo engraved. Thanks to the sunburst finish, a play of lights is created: different layers of colour emerge, sometimes warmer, sometimes cooler, depending on the light it reflects.

35 components, CNC numeric machine crafted, all made one by one and then assembled into a case

The result is a brighter timepiece, due to the corners of each component which reflect the light, and a case which seems to be crafted in just one piece. The overall architecture is assembled by hand and tested for days before passing the demanding quality controls. In-house engineering studies, bespoke developments, and technical solutions are essential for our complex case construction.
