Omega 563 movement questions / help

I have two omega 563 movements, one 1967 which is a quick date push-pull.

The other 563 is a 1970 and is not a quick date change.

I thought the earlier was a back & forward quick change than the push-pull date change. So did they do away with the quick change date sometime between 1967 and 1970?

Both are in excellent condition, which would be the better movement to keep??

Thank you in advance for any help

I suspect that you have a 563 with a broken date setting dongle (part 1568 - Correcting Yoke).

Thank you for the reply.
If that part is broke would you still be able to change the date?

Thanks again

Just keep rotating the hands until you get to the date you want, depending on how many days you need to advance it might take a while.

One movement is that way but the other is a push-pull date change.

If a watch doesn't perform IAW manufacturer specifications, it would be risky to keep operating it.
Take the suspect movement to a reputable watchmaker to see if there is a problem or a missing part.

So All 563 movements are push-pull quick date change???

Thanks

Yes.

Your watch has a problem. Just take it to a watchmaker.

It's not unusual, see this post referring to a caliber 565 (same base caliber as a 563).

The kaliber 565 could be said to be the base caliber for the 564 (same jewel count, chronometer-rated) and the 563 (lower jewel count for the US market). The same goes with cals 552, 562, 752. Subtract 1 from the caliber number to find the chronometer version and a further 1 to find the US version.

The part that is most likely to have failed (as it is designed to do when the load becomes too high) is this one:


You won't see it in that other thread because it has the steel design that we usually replace with the one above. This is the best advice:
Yes.

Good luck, Chris

Ok, I checked again and pulled a little more and it works as it should. I was just cautious about pulling to much and damaging the stem.
Thanks again for the help.

You get a like from me and a laugh out loud.
This is not at all uncommon with anybody new to a quickset date.
