·Just got this Omega today.Previously owner dind`t know anything about it so i had to open it up.I belive its a Omega cal.20 NN based on the measurements i did. D:43.8mm H:8mm and the keyless work but haven`t got time to do the reasearch.So please comment if you know anything about it.Runs great but missing the original hour and minute hand and one wrong srew holding the movement in place.It`s not a high end watch but i like these old movements and the research around them.
