From 1947 until 1962, Rolex produced a series of rare and innovative triple calendar chronograph wristwatches. These included the references 4767, 5036, 3036 and 6236. Produced in very limited numbers, they were made in yellow and pink gold, as well as stainless steel. Initially known as the Dato-Compax, today they are more generally referred to as the "Jean-Claude Killy", named after the three time French Olympic ski champion, who was often seen wearing a model 6236 like the present timepiece. Over the course of the model’s 15 years of production, Rolex modified both the case and dial for a more refined, cleaner look with the reference 6236 being the final model of the series, featuring a three-piece case with a larger, more prominent bezel.

The present example is very well-preserved with a beautiful and original dial highlighted by the outer blue calendar ring with closed 6 and 9 numerals and embossed Rolex crown at the 12 position. The double faceted, polished numerals embossed in relief have aged nicely through the years with the luminous hour markers and hands aging to a lovely light brownish hue. Today’s collectors are seeking timepieces that not only define their collection, but help establish the historical timeline of a brand. A "Jean-Claude Killy" is an important step in the evolution of any collection – a “must-have” trophy watch for discerning connoisseurs seeking to own one of the most prestigious and complicated watches ever made by Rolex.
