This is an early 7009A movement Seiko automatic. This movement was made in 1970 (this example I bought in 1972) and it became the standard in Dive watches, and Seiko's top end autos through the 70's and 80's with only slight changes.
This movement, and it's more modern family can be identified by the crown between the 3 and 4 hour on the case.
At 21,600 BPH it was competitive with the best of its era...About 6 beats per second.
Lume is still pretty good for a watch of this era.
A very durable movement, it cannot be hand wound but the rotor is bi-directional and when fully wound has a respectable 47 hour power reserve.
