Seiko Serial Number and Movement Info

[WatchDog21 3,345]

I was curious about my latest Seiko purchase; a vintage Seiko 5. A quick google and found this handy little resource for anybody else who may be interested.

 

Mine was produced in March 1976 and the movement; a 6309 was ranked as #2 of the top 50.
