The Oyster sealed the case a century ago. In 1953, the Submariner opened the deep. And in 1970, the Triplock winding crown let it descend to 300m (1,000ft). Our triple waterproofness system creates three sealed zones between the movement and the sea. In Oystersteel and yellow gold, 41mm, calibre 3235. #Rolex #Submariner #OysterStory
