Can anyone tell me about this Seiko?
I'm interested to know the history of this particularly model. I believe it's from the 70s. The dial reads Seiko, 23 jewels. Unfortunately, I am unable to show shots of the movement, as I know that would help.

Answer:
Hi,If you look through caliber chart, you'll find 15xx section including 1520A, and B you get some idea of size of movement, beat per second, etc.,since yours is a 23 jeweled valiant, it must be the cal. 1520B, very good movement.
The serial number 951728 indicated watch must be made in May of 1969.
Best regards,
