Cal 503 Case Clamp Screws

Hey all,

I’ve been looking for the correct part number for the case clamp screws for a Cal 503.

Any help would be appreciated!

Thanks,

Jordan

Case clamp screws and case clamps are related to the case reference, not the caliber.

You can search material houses like Cousins UK for their parts lists.

Why would they be tied to the case when the threads are on the caliber?

The case is a 14746

They are still considered case parts because that's how Omega classifies them.

Understood. Makes zero sense to me that it dictates the type of screw used within the movement, but fascinating piece of knowledge.

I requested a quote from Cousins as it is not in their system.

Any other recommendations for trying to find them?

As shown in OPs post above, 2281 should be the case clamp screw for caliber 503. I think it is the case clamp that is dependent on the case reference, but the screw is movement specific. Hopefully an expert can correct me if that's not right.

That makes perfect sense, but will wait on another opinion.

It's not a part necessary to the functionality of the movement, it's function is along with the case clamp is to hold the movement to the case.

But its size isn’t really dictated by the case, but rather the movement?

OK

 

[blkrush]

Is Rendo correct is assuming it’s 2281 for the case clamp screw?

Case clamp for 14746 is 470.1911

Case clamp screws for Cal 503 were originally specified as 2281. Subsequently updated in a service bulletin to 2297.

Both show up in a quick eBay search.
