Elgin Seaman, 17 Jewel, 687 Movement with Fancy Case
Picked up a very nice 50’s Shockmaster. It has a fancy stainless steel case with with engraved circles on the bezel flared lines on the lugs. Overall, the stainless case is great shape and the dial is clean.
The movement is the manually wound 687, with 17 jewels. As far as decorated cases go, they were far and few between in the 1950s as far as I know.
