Reference 6263 was introduced to the market in 1969 until late 1980s. Compared to first generation examples of the Cosmograph Daytona, the model featured screw down pushers and thus carried the “Oyster” designation on the dial. The movement was also updated from a Valjoux 722 movement to the more reliable Valjoux 727 movement.
