Gold hands with silver indices - something’s not right there
Pics aren’t hi-res enough to be sure but the font is very well done if it is a redial.
It shouldn’t have mixed Ms but Omega did some odd things with Connie dials at the end of the 60s / early 70s. (Including mixed Ms but usually below the centre of the dial)
Do you know what ref it is and the movt serial number?
This might give a clue as to whether it is an Omega oddity.
