The iconic reference 6236 from Rolex combines a triple calendar with a chronograph making it one of the most complicated models ever produced by the brand. 

Reference 6236 is the last iteration of a series of Dato-Compax models first introduced by Rolex in 1947. It started with the reference 4767, which was the brand's first triple calendar chronograph fitted in a waterproof Oyster case, and subsequently encompassed references 5036, 6036 and 6236. What differentiates the 6236 from its preceding models is the more modern case design and dial layout. Namely, instead of having a mono-bloc case like the Ref 6036, the 6236 is equipped with a three-piece case that has a separate, slightly larger bezel. The dial is also cleaner, with a prominent Rolex crown at the top and with closed 6's on the scales that give the watch a more modern character. All four Dato-Compax series had relatively low production numbers and the reference 6236 was produced from 1958 to 1962, with the present lot dating back to 1960 which places it in the middle of the production run. 

Collectors eventually gave those Dato-Compax models the nickname 'Jean-Claude Killy', after the famous Olympic skiing champion. In addition to winning three Olympic gold medals, he later became an ambassador for the brand and even sat on the board of Rolex S.A.
