Gerald Charles lists it at $23,800 before sales tax and currently marks it sold out. The specifications below come from the manufacturer; they are not independent test results.
What makes this the yellow Tennis model?
Gerald Charles describes a grainy-textured yellow dial with applied Arabic numerals at 3, 9 and 12. The case is Darkblast Grade 5 titanium, paired with a yellow Velcro strap that the brand says is developed and hand-stitched in-house. This is distinct from the separate Maestro GC Sport Tennis White, which has a white dial and strap.
The official product listing also says the watch was “Tested and approved by ATP professional tennis players: Andrea Vavassori and Alex de Minaur.” That is the manufacturer’s statement, not an independent assessment of the watch.

How the sport-oriented design is intended to work
Gerald Charles places the screw-down crown on the left side of the case, saying the position is intended to prevent rubbing during sport. The brand also describes its ErgonTeq standard as covering the lugs, case and strap, and says the strap accommodates multiple wrist sizes. Those are design intentions and manufacturer fit claims; they do not guarantee comfort or fit for every wearer.
