Gerald Charles has announced a new partnership with Australian tennis star Alex De Minaur, the current world No. 6 on the ATP Tour.
The collaboration is said to bring together two worlds defined by performance, precision and independence, with De Minaur deliberately choosing to align himself with an independent watchmaking maison as opposed to one owned by a luxury group.
Turned professional in 2015, De Minaur is widely recognised for his exceptional speed, defensive skills and relentless intensity on court – traits that have earned him the nickname ‘Demon’. In July 2024, he reached a career-high singles ranking of world No. 6, cementing his position as Australia’s leading male tennis player of the past two decades. His Grand Slam record includes multiple quarterfinal appearances at the US Open (2020, 2024, 2025), Roland Garros (2024), Wimbledon (2024) and the Australian Open (2025).
De Minaur is currently competing at the Australian Open in Melbourne running from 19–31 January, where it’s a strong watch game he’ll be serving too, wearing the Maestro GC Sport Tennis in Yellow, a head-turning, tennis-ball inspired model from the GC Sport collection that has since sold out.
Designed with professional athletes, the super-light GC Sport collection is crafted in Grade 5 titanium, features a left-hand screw-down crown and Velcro strap, and meets the brand’s Ergonteq standard for optimal wearability.
“I am incredibly proud to partner with Gerald Charles,” said De Minaur. “People who know me know I am a watch guy. To represent and work closely with a brand founded by Gérald Charles Genta and built in his name and vision is something very special to me. I am beyond excited to work with such a unique company of horology enthusiasts and can’t wait to get started on my own signature line.”
Federico Ziviani, CEO of the brand, said the choice was driven by more than his on-court success: “We chose Alex not only for the exceptional professional athlete he is, but also for his genuine passion for fine and vintage watchmaking. Beyond his performance on court, we were impressed by his cultural sensitivity and deep appreciation for horology – values that resonate strongly with the spirit and heritage of Gerald Charles.”
