Does anyone have any idea how many 6215-7000's were produced or where that info could be obtained? Is there a 6215-7000 enthusiast club? Does SEIKO answer questions like that? New to this - trying to catch up fast. Thanks for any help. Geo

I think you might be better off posting in the Japanese watch section rather than the Vintage watch review.

You'll likely have to do some Sherlocking to find this out.
If you find the years of production and then search for biggest serial numbers for each month of production(using image searches) - you'll be somewhere near.
Seiko are not very forthcoming with these type of figures.
Hopefully someone here can help you with production dates.
