Rolex Chronograph 6236

Reference 6236 is the final and most refined iteration of the “Jean-Claude Killy” Dato-Compax, produced from approximately 1958 to 1962. It is a ‘grand complication’ for Rolex, powered by the manual-wind Valjoux 72C movement. This caliber integrates a triple calendar (day, date pointer, month) with a three-register chronograph. The technical specification is a 36mm Oyster case with a two-piece bezel and pump pushers. The 6236 is significant for its larger case size and improved water resistance compared to its predecessors, representing the ultimate evolution of Rolex’s most complex wristwatch.
