Rolex may have been Official Timekeeper at The Open for the 38th consecutive year in 2018, with endless hours of screen time for its branding, but none of its testimonees got their hands on the Claret Jug as Italian Francesco Molinari won the tournament. Mr Molinari currently has no watch sponsor.
The best-placed Rolex testimonee was Jordan Spieth, who finished five shots behind the winner.
Audemars Piguet, which has built what it calls its dream team of golfing ambassadors over recent years, was better placed with Xander Schauffele challenging until the final few holes and finishing joint second.
The AP brand ambassador roster is made up of 10 international golfers including Lee Westwood and Ian Poulter, who did not challenge at The Open.
Danny Willet was the best placed British ambassador, finishing 24th at -1.
