A woman was arrested for stealing a man’s $30,000 Rolex watch on Saturday — when cops discovered it hidden inside her panties, law enforcement sources said Sunday.

Danielle McGee, 27, met the victim at TAO Downtown in Chelsea before heading back to his apartment early Saturday and swiping his Rolex Daytona, according to the sources.

Once he discovered the watch was missing, he called police, who used a metal detector to get a positive hit on the woman.

McGee was taken to a stationhouse, where the watch was recovered. She was charged with grand larceny and criminal possession of stolen property.
