Hi all. I wonder if you can help me out confirming the manufacture date of my 7006-7002 with serial 172065.

I always thought it was a '71 watch and recently advertised it as such (not here). I had an enquiry from an interested buyer, but he came back to me today saying he was really looking for a '71 birth year watch and several online seiko watch date calculators had informed him it was manufactured in 81.

I found such a tool built by Cannop of this forum and of course the SCWF production date calculator. Each of these tools seems to indicate the start date for the 7006 movement was in 1972. However, Ranfitt and a couple of other sources (unattributed wikis etc) show production commencing in 1970.

There is nothing out there that gives me an end date to confirm the movement/model did or didn't make it into the 80s.

On the off chance, I emailed Seiko Japan, but I don't know if they respond to such requests for info.

Can anybody help me out? I'd hate to lose the sale just because I can't confirm the manufacture date.

I don't think the production date calculator can be relied on here, if the movement was produced for more than ten years - it gets confused.
The style of the watch looks more like 70's than 80's IMO.
Here's Adriano's calibre guide, which states that the 7006 was introduced in 1970

The only way to know for sure, is to find it in an old Seiko catalogue.

Mystery solved.

I sent an email to Seiko's customer service in Japan and they were very helpful.

"Dear Mr. Patterson

Thank you for your patronage of SEIKO products.

We are unable to give the exact production date, but we can tell you that
your watch (Case no. 7006-7002) was produced in 1971.
For your information, according to our data base, the starting year of this movement (7006) was 1970,
and this model/case (7006-7002) was started producing in 1971.

Therefore, we can assume your watch was produced in 1971, not in 1981.

Regarding the parts for 6309-7040, we regret to inform you we have no original parts inventory at all.

We appreciate your kind understanding, and we sincerely hope this answers to your inquiry.

With best regards,

CS Dept.
SEIKO WATCH CORPORATION"

No surprise to anybody I'm sure, but they don't have any original 6309-7040 dials in stock. Doesn't hurt to ask :)

I was surprised they gave the level of detail they did.

Perhaps it was the use of formal Japanese greetings and thanks in my email. The Japanese are generally a very polite people and perhaps my respect predisposed the responder to answer as comprehensively as possible.

Wow that is fantastic. Great job with the email and the proper respectful tone.

I think we all suspected 1971 and that 1981 was too far out but now you know 100% for sure.
