Question: when did Rolex go from Officially Certified Chronometer to...

    Superlative Chronometer Officially Certified?

    Looking at a 1013...maybe to buy...but the dial says Officially Certified Chronometer...not Superlative Chronometer Officially Certified.

    I know that the 6599...which preceded the 1013...was an Officially Certified Chronometer. That was with the 1530 movement. My understanding is that when Rolex went to the 1560 movement, it became Superlative Chronometer Official Certified. The hands and dials and everything else about the two models stayed the same during the initial transition. Only the movement and the legend on the dial changed. My thought is that perhaps someone replaced the original 1013 dial with a dial from the 6599...or Rolex was using up the old 6599 dials before issuing the later dials. These are the only explanations I can come up with. The movement is a 1560, and the model number between the lugs is 1013.

    Any other thoughts or experiences you can add will be helpful...changes like this with other models...Subs, Explorers, DateJusts, etc.

    Your responses are appreciated
