Sir Ben Ainslie, the British Olympic yachtsman and a Rolex brand ambassador, has been robbed of his watch at knifepoint in Barcelona.

The yachtsman, who is in the city to lead the U.K.’s Ineos Britannia team in the America’s Cup, reported the theft to local police in Barcelona on Monday. The Telegraph was first to report the news.

Coincidently, Rolex released on Monday a new video featuring Ainslie. But the video is about the 34th edition of the Maxi Yacht Rolex Cup, not the America's Cup.

“Like in all big cities, you can be affected by opportunistic crime and my situation is no different,” Ainslie told The Telegraph.

Ainslie was cornered by a gang and robbed of the Rolex watch reportedly worth €20,000 ($22,250) on Saturday, Spanish police said. In light of the mugging, the police said they will bolster security at the America’s Cup, which began on Aug 22.

The police did not reveal the exact Rolex model. On its website, Rolex says Ainslie wears a Yacht-Master 42 in 18 kt white gold.
