John Mayer sues Charlie Sheen's friend over phony Rolexes

The singer wants almost $700,000 back from "close friend" Robert Maron for allegedly having been sold timepieces containing knockoff parts.

The 36-year-old singer has filed a lawsuit against against Robert Maron, the watch dealer to the stars who sold him $5,000,000 in pricey timepieces. Mayer claims seven of them were designated as "counterfeit" by Rolex.

According to the complaint, filed on Tuesday in California Superior Court, Maron, 54, is identified as a broker and expert on "important" watches -- primarily by Rolex and Patek Philippe -- who sold items to the singer beginning in 2007.

Over the years, Maron became Mayer's "close and trusted personal friend," the complaint states, to the point where they were spending vacations together and Maron was accompanying Mayer on tour.

The claim continues: In 2010, Mayer sent one of the Rolexes to Rolex for servicing, at which point he was informed by the Swiss company that the watch he had sent them "was not authentic in all respects." Namely, parts contained within the watch were not Rolex parts. Mayer confronted Maron at the time, and Maron apologetically gave a refund, according to the lawsuit.

Mayer then proceeded to buy more watches from Maron -- to the tune of approximately $5,000,000, the lawsuit states. Then, in 2011, Mayer learned another Rolex watch sold to him by Maron contained a bezel and dial that was not authentic, rendering it counterfeit, the suit alleges. Further investigation by the company confirmed that at least seven watches sold to Mayer by Maron were allegedly counterfeit.

Mayer is seeking $656,000 -- the purchase price paid for the seven watches -- plus interest and damages for five causes of action, including fraud, breach of oral contract and negligent misrepresentation.

Maron attorney Eric George called the suit "factually meritless" in a statement to The Hollywood Reporter.

"Robert Maron has a more than 30 year reputation as an internationally renowned watch dealer. John Mayer, who briefly claimed expertise in Rolexes but now has apparently changed his mind, has brought a lawsuit that is legally and factually meritless," the statement reads. "Mr. Maron refused to pay Mr. Mayer a cent to settle his frivolous claims, and will instead defeat them in court."

A close friend of Charlie Sheen -- who has reportedly sold the actor over $10,000,000 in luxury watches -- Maron was made a co-executive producer on Sheen's sitcom Anger Management.

"He has incredible taste," Sheen has said of Maron. "He's the most astute player in the game. He truly is, in my opinion, the market maker."
