The reference 6036 Antimagnetic chronograph with triple date was produced in few examples from 1958 to the early 1960s in yellow, pink gold and very few in stainless steel, with various dial designs and hand shapes. The ref. 6036 and 6236 are known among collectors as the 'Jean-Claude Killy.' Mr. Killy was an internationally renowned world ski champion in the 1960s and remains as the classy ambassador of Rolex in numerous advertising campaigns. The main difference between the 6236 and the 6036 is that the 6236 has a three body case and the 6036 has a two body case. Examples featuring the retailer's name on the dial are very rare such as this watch sold through the famed retailed Serpico Y Laino in Caracas Venezuela.
