From 1947 until 1962, Rolex produced a series of rare and innovative triple calendar chronograph wristwatches housed in Oyster cases, encompassing the references 4767, 5036, 6036 and 6236. The reference 4768 also bore a triple calendar chronograph complication, however in a non-Oyster case. Produced in very limited numbers, these references 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 and Rolex ambassador. After production of reference 6236 ceased around 1962, Rolex would never again offer a model with similar complications.

The present, early reference 6036 bears a charismatically aged dial, resembling ivory parchment that has turned a beautiful beige hue over time. This change in color contrasts wonderfully with the blue outer date track and the stainless steel case.

The dial’s wonderful, recessed small, silver-finished square hour markers are correct for the reference and era. It features a bright blued steel calendar hand to complement the blue outer calendar track typical for this reference. Its case is remarkably well-preserved, thick and still sharp, indicating it was worn carefully over its lifetime.

This is an exceptional opportunity for the astute collector to gain a renowned and hallowed reference, the most complex chronograph wristwatch ever produced by Rolex.
