Bulova 1949 Pacemaker
Seems to be a manual wind. was able to pop the back off, but the movement is attached to the back case and the dial came out with it all as one piece. therefore can't see a movement code or serial. no other markings other than the case serial and "bulova" inscription on the back.
Should date to the 50s-60s but I can't find any exact matches thus far.
