Air king question ?

[Gogetter]

I have been looking at preowned models, and some say
"Precision" on the lower face, and some have the words
"Superlative Chronometer Officially Certified" in the same
area.

Is this important or ?

Probably indicates a change when they started certifying the movements to COSC standards. I'll leave you to research what COSC means

Welcome to the Forum! There are many different model Air King watches available from over the years and are referred to as "references". Some of the references may be COSC certified and others may not. As mentioned above, do your research on the different references and you will find your answer.

It's your call. (1) Precision=manual wind (2) Perpetual=self-winding (3) Superlative Chronometer Officially Certified= adherence to the COSC specifications (at the time of its production).

Thanks for that. I am looking for a watch that will only be worn
occasionally, and a manual wind may be the best for that.

Precision does NOT mean manual wind.

IIRC, no wording above the 6 means 17 jewel movement. Precision meant 25 jewel non-COSC movement. Super Precision meant non-COSC 1530 movement. I'm not sure about later sapphire crystal AKs but no acrylic crystal models were COSC.

Incorrect

Please clarify. While a Precision movement is non-COSC, the ones that I have seen have all been manual winders so perhaps I wrongfully assumed that the two go hand-in-hand. Was there ever a Rolex dial designation for a 'manual wind' like there is for an automatic (i.e. perpetual) or do you just shake to watch to see if there is a rotor?

Just Oyster or Oysterdate, with no Perpetual.

Got it! Oyster/Oysterdate (no perpetual)=manual wind & Precision=the non COSC movement.

Superlative Chronometer Officially Certified

Does not have anything to do with COSC or COSC certification, they are made-up words by Rolex.

COSC did not come into existence until 1974, after which all Swiss watches had to pass to be able to legally put "Chronometer" only on the dial.

The word Precision appeared on Air King dials (although not all of them) from the very earliest manual-wind models of the mid 1940s through to the last 140xxm series in about 2007, when it was replaced with Superlative blah blah on the 1142xx series.
