Seiko 7A38 - by the numbers

An appreciation of the World's First Analogue Quartz Chronograph...

and particularly of the 7A38 day/date version, in all its many and various guises.

 

Hello, and Welcome to what I hope will become THE #1 Resource for Seiko 7A38s (including associated 7Axx 15J calibers and their derivatives). 

Please note: At its inception, in late January 2012, this site was intended primarily to be a blog. If you click on the next 3 tabs: News, Blog, Photos you will get the impression that very little has happened since then – which would be completely wrong. Whether it was a correct decision or not, a little over a week after the site was created, I added a forum module. Since then, 99% of all activity has taken place there. Click on the Forums tab and you’ll find 700 topics containing over 11,000 posts and a similar number of photos – and hopefully what you were looking for. Enjoy. PS.
