Stepping up in Gerald Charles's range
The Maestro line has always sat at the intersection of Swiss movement craft and athletic utility, but this edition makes that tension explicit. Limited to 200 pieces, it was designed in direct consultation with professional tennis players — the left-hand crown placement is not an aesthetic choice but a functional one, moving the winder to the opposite side of the case so it never presses into the wrist during a backswing. The optic yellow dial, textured with a porous, grainy finish that reads unmistakably as a tennis ball, carries the theme without becoming a costume. At 39mm across and 9mm deep, the titanium case wears considerably lighter than those numbers suggest: 64 grams including the strap, with the ErgonTeq® geometry distributing that weight across the lug-to-lug span rather than concentrating it at the centre. The integrated Velcro® fabric strap shares the dial's yellow and the rubberised underlining handles sweat without compromise. Beneath the sapphire caseback, the GCA 3002 — developed at Vaucher Manufacture Fleurier — runs at 4Hz through a twin-barrel 50-hour reserve, and its open-worked rotor carries a geometric pattern marking Gerald Charles' 25th anniversary: a detail that rewards the owner who thinks to look.

Learn more about Gerald Charles
Gérald Charles Genta designed the two watches that defined the luxury sports category — the Audemars Piguet Royal Oak in 1972 and the Patek Philippe Nautilus in 1976 — along with work for Omega, IWC, Bulgari and others. He was called the Picasso of watches, and he was not especially modest about it.
He founded his first eponymous company in 1969 and sold it to The Hour Glass in 1996. In 2000, at sixty-nine, he started again with Gerald Charles, using his first and middle names.
This was the brand he made for himself rather than for a client, and the Maestro case shows it: deliberately asymmetric, with the right side of the bezel curved differently from the left, so that it sits against the wrist rather than sitting squarely on it. No brief from a manufacture would have survived that decision.
Genta died in 2011. The company remains independent and family-owned, run by the Ziviani family, producing the Maestro in small numbers.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
Yes. At 100m it is rated for swimming and snorkelling, though not for diving.
Water resistance explainedWill the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Sapphire, mineral and acrylic comparedDoes it need a battery?
No. It is automatic — the motion of your wrist winds it, and there is no cell to replace.
Quartz, automatic and solar comparedHow long does it run for when it's not worn?
About 50 hours fully wound — enough to survive a night off the wrist, but not a full weekend.
What size strap does it take?
22mm. Any strap of that width will fit, and on most modern watches quick-release bars make the swap a two-minute job with no tools.
Will it fit my wrist?
Lug-to-lug is 46.80mm, which suits wrists from roughly 16cm (6¼ inches) upward.
Lug-to-lug decides fit more than case diameter does.
