What month year did the 6309's stop, and the 7002's start?

Reading over the "How to buy a 7002 diver" thread at WUS, looking for production information.

Does anyone know the specific month that 6309's stopped?  Like what's the latest example we know of?  And when did the 7002's start?  Like, what's the earliest example that we know of?

I have a 7002-7009 from May '88.  That's early.  But how early?

The earliest 7002 that I have is April of 89 and in the 6309 my latest is Jan 1985.  So I am know help in your search.

I don't know what month.  All I can provide is this link from TOF going to the diver's reference page:

Both the earliest 7002 and the latest 6309 I have seen date to early 1988.

Seiko doesn't just flip a switch one day to cease production of one model and start production of another, so there is no one date we can go by.  There is always overlap and a gradual "phase out" which can take some time. 

Similarly, the latest 7002s we see are from 1996...as are the earliest 7S26s.

I figured there'd be an overlap when one line stopped and the next one started, but I wanted to know what those were.  Like how we know that the earliest seen 6139's are from February '69.  And the latest 6105 I've ever seen was October '79 (though we think that was a repair case back maybe).

Oh, I see.  If you are asking about the 6309 and 7002 separately, I think the earliest 7002 I have seen is April, 1988 and the latest 6309 is January, 1988.
