I really find it hard to believe there's a need for such a topic, but apparently it exists. Recently I've been running some analyses on incoming google searches that have brought visitors to the forum.Over the last 28 days, 5 different visitors have arrived at various topics, trying to date their Seiko 7Axx's !
Has anyone seen any older or newer Seiko 7A38's than these two ?
Incidentally, I just had a quick scroll through my Excel spreadsheet of my 7A38 collection and ....
The newest 'Made in Japan' 7A38 I own is a gold-tone 7A38-7289, with a serial number 965611 - meaning manufactured in June 1989. You're correct in that there doesn't (yet) appear be a single topic on the forum dedicated to the Seiko 7A34.
However, they are mentioned, on numerous occasions in various threads in different sections of the forum.

Any help that you can provide would be just awesome for me.Earlier today, a UK visitor arrived (at a competely inappropriate thread) by googling: The original link to John Gauch's Seiko Production Date Calculator still exists: now re-hosted by SCWF: unfortunately neither appears to work any more.Others have come up with alternative Excel-based solutions. showtopic=33736&view=findpost&p=703869 (clicking on embedded link downloads). But to work out the date of manufacture of a Seiko 7Axx (from the case-back 6-digit serial number), you don't need a calculator. Seiko 7Axx's were officially produced (by Seiko*) from 1983 to 1989, although a number of 7A28's were manufactured in late 1982. were still producing Yema N8's using re-branded (Shimauchi V906) movements up to 1994.Seiko Production Date Calculator dating seiko watches calculator Topic).Jul 21, · Seiko Production Date Calculator Sign Up to reply and join the friendliest Watch Forum on the web.
