Omega 1012 Movement Spares

[Moose]

Hello All.

I have an Omega 1012 movement with a damaged Date Corrector Yoke (Part 1568). I think it is a common fault, where one or more of the small teeth get damaged on the hour corrector pinion. You can see the missing tooth in the microscope shot below. The other photo is of the complete part, for reference.

Cousins are showing a spare part for this, but they list it as being for a 1010 movement. The parts list for a 1012 seems to hint that part 1568 is "different for cal 1010 and 1020".

Would anyone know if the Cousins part can be used or not? I am reluctant to purchase as its an expensive part (£56.16) if I can't use it.

The Technical guide suggests it's a different part too. Hope these sheets are of use to you, I've inserted them in order (the first picture is a close up of page 2):

I have an idea, that the part is different depending if you have a day/date movement (1020) or just a date only version (1010, 1012)?

As far as I can see looking at the technical docs, one has two "star" pinions on the upper part, for manual correction of both day and date, whereas the other version of 1568 has only a single "star" pinion to correct date only.

I'm wondering if the rather 'cryptic' technical note is meant to mean that the 1010 version (date only) is different to the 1020 version (day/date)? 

That would seem to make sense because the 1010 and the 1012 are virtually identical apart for a couple of other parts, not related to day/date correction.

This is the 1568 version from the 1020 and up versions, clearly with two correctors.

I think that's the case indeed. Check this true auction ending soon

Shame. I was looking at that and got outbid at the last minute.

Ah well, may need to cough for the Cousins part.

Because serious buyers most often use snipe bidding. So if it's important, one must commit to bid (better if by sniping) the actual maximum that he's willing to pay.

Agree 100% if I see something that I really want or need I bid high. The snippers will have it if not.

I've ended up with a couple of these 10xx series movements for spares - but not your part unfortunately. Prices for some of the new parts do seem excessive, but I guess the suppliers aren't getting and new parts in stock.

In my small collection of Omega (7) I have 4xx, 5xx and 6xx series movements which I think are more robust than the 70s 10xx movements. They just seem a bit fragile to me.

if you go to cousins and download the 1012 parts list you will see that it only lists the parts unique to that. The part you seek is not on this list and it refers you back to the 1010.

then if you go to the 1020 list you get the same thing it lists the different parts and your setting part is here indicating it is different then the 1010.

 

then I find looking at lots of references is helpful like this one.

then click on the part and get this one.

you get the cross reference and you get this part number  72210101568.  so if you look carefully you can see the base caliber here 1010 and your part number 1568. Plus of course you get all the watches across references to which is not the 1020.

probably a common fault because people are not lubricating correctly.

One of the problems with some watch companies is a scatter their technical information across lots of different documents. So lubrication oftentimes isn't covered because that's in the lubrication guide. Or they'll have guides for groupings a calibers with similar things. For instance the image attached you will note common lubrication for both the 1012 at 1020 but notice part numbers are different. Exactly what the links above show.

Very helpful information, many thanks.

I have ordered the part from Cousins now, so this info is essential to me refitting it correctly lubricated. And you are right, there is no lubrication info anywhere about this in the 10xx parts lists I have seen thus far. In this case, I would just normally just follow the basic rules, generic to most movements.

It tells you where to lubricate in the technical guide I posted. 

[Moose]

I know. I said so in my post. Thanks.
