Any idea of the actual production run years for each jewel count.
I've been told the the 27J run was up to 1971 - is that correct?
Just wondering as I notice on the bay that sellers tend to describe the 27J as "much rarer" etc.
I have a 4006-6020 27 Jewels from January 1970Can anyone clarify regarding the 4006-6020 as to wether it was produced as a 27jewel and 17jewel? as my 6020 is a 27 jewel and my other 6021's are 17 jewel. I have been informed that they are called 6020/6021 because the large or small stem tube is this correct or does the 6020 relate to the 27j and the 6021 relate to the 17 j?

Beautiful collection,would love one of the rare models like your 4005.My collection this is my lot 2x 4005 and 1x 27j and 2x 17j 6021 one of which I have swapped out the original black enamel bezel for the blue, just something different
Yes actually saw that one myself,Including the two already mentioned above I have seen four Diashock this year. Both had also no mention of Diashock.Oddly enough, I saw another december 66 diashock for sale just recently on the usual place. Its in a bit better condition but no bargain at USD1000. I'm not sure the owner knew how rare it is, it was just listed as seiko 4006 7000.
