Help With Seiko Identification

I can't answer your question on 7T34's, as such, but I can confirm that there appear to be numerous anomolies in Seiko's cal./model case-back stampings.

Since I started collecting 7A38's, I have seen several examples of this - most recently a two-tone 7A38-728A which to all intents and purposes was EXACTLY the same watch as identical appearing 7A38-7289's which I'd seen previously.

There also appears to be much 'crossover' in the marking of other 7280's and 7289's (and other models in the 7A38 range).

In fact, I asked a very similar question (specific to the 7A38-7270) in one of my very first posts:

http://www.thewatchforum.co.uk/index.php?s...st&p=404997

I have 2 of this particular (exactly the same model) Seiko 7A38 - but both mine are marked 7A38-7270.

Could the OP have made a typo with his original subject, or are Seiko model numbers more complicated than I'd thought ?

Is there a table of what these Seiko 7A38 model variations signify to be found anywhere ?

well, in the 6309 world, the last number 6309-7040 and the 6309-7049- the NINE seems to be the model slated for the USA. The #0 is seen as models made for everywhere else.

So, the final 9 could also mean that model was made for the USA only, with no other apparent difference.

So I wonder what the significance of the last digit of the model - '0' or '9' (being most common) being replaced by 'A' is ? :huh:

Compare for example these two 7A38's recently sold on eBay - in the USA:

7A38-728A item # 150332039775 and 7A38-7289 item # 150333270192

(My own watch, which came from eBay in the States (NIB) is also stamped 7A38-7289.)

Noting also the OP's original question:

Is the Seiko 7T34-6A0A in the same model range as the Seiko 7T34-6A09?

Hi folks, just joined the forum and I have a question regarding Seiko model numbers.

I still have my 6309-7049 Divers that I purchsed in the Bahamas in 1979. I dont know whether the watch was destined for the US specifically, or world market.

What I do know is the day ring has both English in black and Spanish in red which I thought was intersting, was this a standard configuration from new?

Thanks for any feedback, (I hope to post a photo when I can figure out why google photo URL wont load!)
