1977 Seiko on NATO today...
Why not? Times change 😀
Do you know much about vintage Seiko digitals? I've got a circa '77 that was my grandfather's, and he got it wet just after buying it, so its been dead the last 35 years, but it was one of Seiko's top models at the time, and the case is mint (since it broke before it could be worn) even has full box papers and receipt.
