I had been led to believe that this dial was for a 491 however unfortunately it does not fit. Now I'm trying to figure out which movement it does fit. The dial is 27.5mm in diameter. The feet are close to 11 and 5 and 18mm apart. Any help is appreciated.
A friend has a 351 plate which it fits on but the 351 does not have a subsecond hand so it obviously that's not the right movement. So maybe a bumper movement from similar time like a 342?
