Got this watch on ebay for 50 dollars. One of the movement hold downs and screws were missing in the back and luckily I had one in my parts bin that worked. From the serial number I think its from 1959 or so. The number on the case back is not the same as the movement but its close so probably an early replacement movement from when the watch was newer? No matter to me though I am enjoying the watch. 35mm wide not counting the crown. Also is it normal for one side of the case to have drilled lugs for the spring bars and solid on the other side?
