Actor Danny Masterson is hunting for the thief who swiped his $20,000 watch during a recent charity softball game in New York's Central Park.

The former That '70s Show star, 33, placed a bag containing his designer Panerai watch in a dugout near the playing field at around 12.30pm on June 6th, according to police.

However Masterson, who took part in the game to help raise money for children in need of neurosurgery, was shocked when he returned to discover his Swiss-made timepiece had been stolen from his bag.

He tells the New York Post, "I waited two years to get that watch. It's a limited edition. They've only released 100 in the world. It's pretty funny. We're at a charity game to raise money for kids, and someone jacks (steals) your stuff. If someone finds the watch, I'll give them a big fat kiss."

No arrests have been made as WENN went to press.
