A Rolex watch was the subject of a dispute late Saturday night between a man and a woman, both intoxicated, on Main Street in front of the Point Bar and Grill. Each of them claimed to own the watch, so an officer took it to the Montauk precinct until documentation could be provided. The watch turned out to belong to neither of them. The man’s father showed up in the morning with a copy of an insurance policy showing the Rolex was in fact his.
