Tennis pro Novak Djokovic is Swiss watchmaker Hublot’s new representative, the company announced this summer. To cement his new position, the current world number one player will sport a Big Bang Meca-10 Ceramic in blue during play at the upcoming US Open in New York.

The news comes as a confirmation of sorts, as speculation has been engendered by Djokovic’s reticence in entering into an agreement with a watchmaker. Many tennis pros reach agreements earlier in their careers, but Djokovic has treaded carefully.

Fellow pro Rafael Nadal hit the ten-year mark with Richard Mille last September, with the RM 20-04 Tourbillon Rafael Nadal, a million-dollar offering, marking the occasion.

Djokovic’s commitment to Hublot will likely result in an initial limited-edition timepiece at some point in the near future, with the tennis star contributing his own ideas to a signature watch as well.

Djokovic has won 20 singles Grand Slam titles. And so have Nadal and Roger Federer—an incredible and unprecedented tie in the world of tennis. Djokovic, however, is a heavy favorite at this year’s U.S. Open, which gives him a big chance of winning a record-breaking 21st Grand Slam. In case of victory, he would also achieve the Grand Slam, having won the Australian Open, Roland Garros, and Wimbledon this year. The only male player to pull off the Grand Slam in the Open Era is Rod Laver; he did so in 1969. (Note: The term ‘Grand Slam’ designates both a major tournament, and a calendar-year Grand Slam, i.e. winning all four majors in the same year.)
