a tribute to tennis tradition and technical excellence
While engineered for performance, the Maestro GC Sport Tennis White embodies the spirit of Centre Court: precision, control and timeless elegance.
A sporting watch shaped by ergonomics
At the core of the Maestro GC Sport lies ErgonTeq®, Gerald Charles' proprietary ergonomic engineering standard.
In-house developed, hand-stitched and with an integrated Darkblast® buckle for added durability and maximum comfort
It has a porous effect that mirrors the texture of the dial and includes an iron core, ensuring both flexibility and strength. The easy removal system allows customers to effortlessly change the strap.
