What type? Dress? Diver? Field? GMT? Lord or King? Hi beat? Price range? The choices are endless and a little bit of filtering would make your ask easier to answer.

 

Thank you @jcohen. I preffer diver and field watches but did't saw one with this specs. I'm new to vintage watches, maybe I don't know where to search. Lord or King? Don't know the difference... 300 will be enough? I saw all kind of prices.

 

For a white dial vintage field watch, I'm thinking SARB013 (38mm). The green version of this (SARB017) is actually one of my favorite Seikos of all time. I don't know many white dial divers, but maybe 6458-600B, though this may be harder to find. I think there are a few white dial diver's in Seiko's current line up, like SRPE37. If you are open to a dress watch, then there are many King Seiko, Grand Seiko and Lord Marvel, Skyliner, and Business A options from the 60s and 70s of various prices, but most will be smaller than 38mm. There are always dozens of examples on ebay.

For a more recent vintage for a dress watch, everyone likes SARB035. And its 38mm.

 

No King or Grand Seiko vintage model is 38mm, mostly 36mm.

Some of their sporty models are 38mm or more, but you'd be better off buying a new Presage or Prospex for that kind of money.

Just my 2 cents...

Even the vintage 62MAS was 37mm. I agree just buy a modern Seiko for a case 38mm or larger unless you want to go for a vintage diver.

As for vintage Sinn (if there's even such a thing) it's hard to beat the hype of an EZM1 Mission Timer with the Lemania 5100 (IIRC German border guard old standard issue).

 

Have a look at the Seiko Actus range of vintage watches. Some of their models appear to be 38mm from my brief look. See the examples below (though I'm sure I'm missing a bunch of viable models).

Seiko 7019-8010

Seiko 6106-8460

 

Thank you all! I have free time today. Guess what will I do?

 

6458-600B is on the top of the list.

 

7A28, 7A38 and 7A48

Best quartz movement ever. 7A48 is a moon phase. You can get them from $200-$500 depending on condition. They can be serviced at the Seiko service center for a out $180. New seals etc.

This is a 7A48. Chromoeter is good to 1/10th of a second.

 

I guess the pre-SKX quartz dive watches are larger. Other than some other 80s-and-up sport watches, most vintage (K/G) Seiko and such stuff is 36-37mm. Which is actually larger than most old watches

 

A few King and Grand seiko have 43mm Lug to lug which make them quite big on the wrist, if you like dress watches those are the ones to go for!

 

 

My advice: Get a Bell-Matic and be the hit of every party! Something about having "an alarm clock on the wrist" brings out the little boy in even the most "boring & stuffy" adult male...
