What if anything is stamped on the back of the case? A picture of the movement would be of great help. It appears that a second long hand may be missing from the center arbor. One hand being stopwatch, the other a lap timer. I am not sure, but believe these timer watches were produced in the 1950's and after.
Here is one in the database dated 1972 that matches yours.
