Maestro GC Sport Tennis

LIMITED EDITION OF 200 PIECES The GC Sport Tennis features a Darkblast® titanium case and a grainy-textured yellow dial with applied Arabic numerals at 3, 9, and 12.

The ErgonTeq® design ensures the lugs, case, and strap sit ergonomically, adapting to all wrist sizes for maximum stability and weight distribution. Engineered for performance and versatility, this timepiece embodies Gerald Charles’ commitment to innovation and comfort.

Crafted in-house in Geneva, the strap is hand-stitched and includes an iron core, ensuring both flexibility and strength. The easy removal system allows customers to effortlessly change the strap, offering a personalized and convenient experience, while maintaining the Maison’s signature quality and attention to detail.
