Raymond Weil, the luxury Swiss watchmaker is suing the Oscar-winning actress Charlize Theron for allegedly breaking an endorsement deal to wear only its watches. In court papers filed late Monday, Weil stated Theron signed an endorsement deal saying that from October 2005 through December 2006 she would only wear Weil’s high-end watches. That deal allowed Weil to use Theron’s photographs in its advertisements in exchange for “substantial funds.”

The suit by Raymond Weil accuses the actress of ‘two-timing’ the company by wearing a Christian Dior watch in public – a strict no-no in her $20 million deal. “If you’re the model for Ralph Lauren, you can’t show up wearing Gucci at the Academy Awards,” said David Jaroslawicz, an attorney for the watchmaker. “She undercut our entire ad campaign.” “We spent a fortune on an ad campaign centered around her,” Jaroslawicz said. “Then she goes off and makes us look silly in the industry by wearing Dior.”
