Carlos Alcaraz was seen reminding his fellow Rolex Testimonee, Jannik Sinner, to show off their matching Cosmograph Daytona watches during the award ceremony at the 2025 Six Kings Slam final. This year, the Italian defended his title at the exhibition tournament by defeating Alcaraz in the final.
In 2024, during the inaugural edition of the Six Kings Slam, Sinner defeated Alcaraz with a scoreline of 6-7(5), 6-3, 6-3 to win the title and claim the $6 million prize purse.

Interestingly, during the 2025 Laver Cup, an off-court moment between Roger Federer and Alcaraz was captured by the cameras. The 20-time Grand Slam champion, who first collaborated with the Swiss watch company in 2001 and later rejoined the luxury brand with a lucrative endorsement deal in 2006, was seen removing his $1.5 million Rolex watch and offering it to the Spaniard for him to admire.
Where Will Alcaraz and Sinner Compete Next?
Following the conclusion of their campaigns at the Six Kings Slam, Alcaraz and Sinner are expected to compete at the 2025 Paris Masters and the Vienna Open, respectively.
The ATP Masters 1000 hard court tournament in Paris is scheduled to take place from October 25 to November 2, 2025. The matches will be held on the indoor hard courts at the Paris La Défense Arena.
In 2024, the World No. 1 was seeded second at the Paris Masters, and he began his campaign in the second round after receiving a first-round bye. He won his opening match against Nicolás Jarry with a 7-5, 6-1 score, but then lost to the eventual runner-up, Ugo Humbert, in the third round with a scoreline of 1-6, 6-3, 5-7.
Meanwhile, the 2025 Vienna Open is scheduled to take place from October 20 to October 26, 2025. The matches will be played on the indoor hard courts at the Wiener Stadthalle in Vienna, Austria.
Sinner’s best result at the ATP 500 hard court event came in 2023. He was seeded second and defeated Ben Shelton, compatriot Lorenzo Sonego, Frances Tiafoe, and Andrey Rublev to reach the final. In the championship match, he triumphed over defending champion Daniil Medvedev to win the tournament, securing his tenth ATP Tour singles title.

I’m concerned and disappointed that ATP has NOT STOPPED the use of
Tech drugs some players are using.
Djokivich when asked regarding a patch on his chest (@ a match)..He replied..
” It enhances my performance..” and Sinner …gets shots before matches from
NASA technology..which has given him a huge edge, even over Alcaraz. THIS HAS RUINED watching tennis for us , as in my mind it IS CHEATING and needs to be STOPPED….
