The chronograph in gold dating from c.1950 is best known as the ‘Jean Claude Killy’ (named after the great French downhill ski racer). The estimate is €12,000-18,000.

Launched in 1947, the reference Dato-Compax was Rolex’s first triple calendar chronograph wristwatch fitted inside a water-resistant Oyster case.

Between 1947-62 a total of four different models were produced – nicknamed after the three-time Olympic champion was seen wearing a reference 6236.
