balance roller

[gary17]

hey

The impulse jewel on this omega 30 t2 has just snapped in two. I see most people say replace the whole roller, but that is not a option (obsolete). The other option is to get a replacement impulse jewel and shellec it into position. 2 problems with that.

1. i am not skillful enough to do it

2. cousins do not have impulse jewel for the 30 t2 model. and i do not no enough about them.

besides being up the creek without a paddle are there any other options?

There is this on ebay https://www.ebay.co.uk/itm/Omega-30T2-Vintage-Watch-Compensating-Balance-Wheel-with-Breguet-Hairspring/353366929831

but you are just taking his word that it is for a 30 t2.  and it seems a bit out of shape at the end you connect to the cock.

cheers

I would really like to see a picture of that?

The reason why cousins and no one else is going to have one is they are never sold for specific watches as far as I know. They're basically a generic component.

But apparently this is watch repair where rules do not always exactly apply? I went to cousins to look for generic roller jewels for you and one of the things that popped up was a roller jewel for 620 Omega? I didn't realize that Omega had roller jewels for specific watches?

So it looks like for Omega they actually do list roller jewel but? I'm attaching an image from the Seitz catalog. Normally for roller jewels you would measure the fork slot with your special tool although those ways around that. As a measure the slot the jewel is slightly smaller and you'd use a generic jewel. Which would work just fine even in her Omega watch. But you still need to have the tool to hold the balance wheel to get roller in it needs some shellac and of course the roller jewel measuring gauge. You could use the feeler gauges used in the machinist world we just need to know the size of the slot.

There may actually be a better solution a compromise. Rather than getting the roller jewel why not get the entire roller assembly? At least with some components like this they cross reference to quite a few watches. So this means you can either try to get the whole roller or any one of these balance wheels will have this roller assembly. So as long as the rulers in fact you can get a smashed balance wheel

hey

Are you saying any roller assembley from a omega watch would probably do. Or just the jewel from any old omega roller assembly would do

I have the number of the roller/impulse jewel for  the omega 260 its 100 1332.

Thanks for helping i am stuck good here.

The link above takes you to the? Okay I went back to redo it again I want to make sure I got the actual watch number correct which looks like I did not. So for this the three letters are the shortened version of Omega  OME 30T2 I assume that's what you have? Okay it looks like my bad I'm attaching a link these are all the parts for that watch if you scroll down to roller there's three of them. So as soon as you figure out which one you have you can click on it and see all the rest of the rollers that interchange. Then yes the roller comes with the jewel of course. So all you need to do is find one of those rollers and who cares about the rest the watch or the balance wheel you just need the roller

Possibly just as well since I was confused as I wasn't paying attention to which model number you had exactly. But we should have enough to work with worst-case it's back to replacing the roller jewel

Hey

Don't they have these at cousins? I'm in UK so easier.

I use the particular site because it has cross reference part numbers if cousins gives you the same cross reference part numbers in use cousin or use wherever you want. Once you get part numbers though they should be good universally with some minor exceptions.

The minor exceptions are unfortunately there's a whole bunch a different systems for numbers. So like bestfit numbers may not be accepted universally. Someone told me for the US material houses that bought out other material houses they usually don't integrate the parts together because there different number systems so they have to keep the systems separate.

So use whatever you want you find out from the listing though that your roller cross references to lots of other omega and a few other brands of watches. So you should build get a roller from somewhere in the universe. The numbers just help you narrow it down

hey

Yer no luck when you follow the numbers through there all obsolete.

Thanks for the help john appreciated.
