When Persol introduced the 714 in the 1960s as a folding version of the 649, it was the first folding sunglasses ever made, requiring ten additional manufacturing steps over a standard pair. Steve McQueen wore them on the set of Le Mans in 1971, and a pair from his personal collection sold for over $70,000 at auction in 2006. The SM edition adds McQueen's name to the inside arm and keeps every detail of the original: pilot shape, keyhole bridge, and Persol's Meflecto flexible hinge system. The Opal Ivory acetate and 24k gold-plated crystal lenses are specific to this Le Mans release. Made in Italy.
