Just serviced and bought back to life. Have left the original paint on the dial and hands as it's in pretty good condition. Watch is running within a minute accuracy over a day.
Not sure if these were intended for either military or medical. It's actually a very small watch compared to other men's models of the same period. Case is about 26mm wide.
We have a few similar early center sweep hands watches in the database:

Case in marked 'BULOVA QUALITY'.
I also like the serial numbers 1196469 (case) and 604609 (movement).
