In 2007, Mayer purchased his first of seven Rolex watches from Maron, a broker and expert on "important" watches primarily by Rolex and Patek Philippe, according to the lawsuit.
In 2010, Mayer sent one of the Rolexes to Rolex for servicing. The Swiss company informed Mayer that the watch he had sent them "was not authentic in all respects" -- some of the parts in the watch were not Rolex parts. When Mayer confronted Maron about the watch, Maron apologized and gave him a refund.
Mayer went on to buy more watches from Maron to the tune of about $5,000,000. But after finding out that seven of the watches were allegedly counterfeit, Mayer filed his lawsuit.
