Legendary surfer Laird Hamilton is riding the Chanel wave, assuming the role of ambassador for the luxe brand’s J12 Marine Watch, a diving watch that is part of Chanel’s J12 series. Designed after a professional deep-sea diving watch, the chic performance piece features readability in the dark, is waterproof to over 300 meters and boasts a matte rubber strap to allow water to flow through–perfect for a waterman like Laird. “This watch is authentic. I have put it through ‘the test’ and it has survived me,” Laird says in a release. In honor of the partnership, Chanel is supporting the Surfrider Foundation, a non-profit dedicated to protecting and enhancing the world’s oceans, waves and beaches.
