Help with an Omega Cal 620 "Click" to Login or Register

HI, I have an Omega Cal 620.

When I got it all seemed well but then it was impossible to wind it up.

I took the crown out and it looked OK so I tried to refit it and it wound up perfect but it would not push all the way in with the usual click and it just pulls out now. It is stopped by the crown hitting the case

It seems that it is not going in far enough to engage properly so there is no way to pull out and reset the hands, as I said it just pulls straight out.

My feeling is that the stem is incorrect and needs to be a bit longer.

Do any of you very knowledgeable folks have any ideas for me please.

Many thanks, Mike

Hi Peter, there is no stem screw it is held in by a button which just presses down to release it. To refit you have to simply push it in until it clicks into place. No way to adjust the position.

Does it have a movement ring..Sometimes if the ring is missing or you forget to put the ring back in, the movement moves just enough inside the case that the stem will not click in all the way..

Hi Gary.

No movement ring.

The stem seems to be meeting resistance rather than clicking in. Almost as if it is actually fully in place. Might be a problem with the setting lever not engaging. ( I think that's what it's called )

Ive realised that what I thought was a stud to push down and release the stem is, in fact, a screw. That was probably why it was so hard to pull out in the first place.

I think I will try and get a new stem and see if that will fit and cure the problem

Thanks for your input.

All the best, Mike

remove hands and dial and look from dial end and see if the setting is in right position as it might have been shift from removing the stem.

You should loosen the screw you thought of as a stud 1 turn (not more) try to fully insert the stem and tighten the screw.

Thanks Gerald I will give that a try.
