Thanks in advance!

Neither of those number Don gave you are what you are after. That is not a screw, it's an eccentric used to adjust the depth of engagement of the teeth between the chronograph drive wheel, and the coupling clutch wheel.

The part is 320-1702 - Eccentric for pivoting of coupling clutch.

Thats why I said to email to be sure. Number is not listed on the parts page unless I somehow missed it

This part was listed for both 321 and 320 - COUPLING CLUTCH PIVOT ECCENTR 1702/OME 27

Emailing and asking for a screw isn't going to get you a better answer. It's the responsibility of the person ordering to know what they are ordering, not the vendor's to figure it out for you (they have better things to do). That's why many will not deal with amateurs, as they don't know the correct names or part numbers most of the time, and suck up a huge amount of time for just the odd part.

Not sure what parts page you are referring to, but it's clearly listed on the Omega parts list from 1958 that is freely available all over the internet - that's where I found it.

I always check out Jules Borel's pages.

I found some PDF files on Cousins site

Yes, to replace it, it will be a press fitted item, that is removed from the underside of the bridge. If it's loose in the hole now and that is the problem, you may need to close the hole up to make it fit tighter.

As an amateur, this hasn’t been my experience. I find the folks at the material houses very helpful and willing to sort out these type of questions if you bring them even a rudimentary amount of information about what you’re after.

Of course they are professionals, so they aren't going to tell you to take a hike. But I've had enough conversations with these people to know that the guy ordering a couple of times a year, who doesn't know really what they want, is not the customer that's keeping them afloat. Customers like these lose them money...so the better informed you are in giving them the right information from the start, the better they can do their jobs and take care of others as well.

The people who they need are repeat customers that are ordering parts, tools, and consumables on a regular basis. Those customers are their priority.

This is why for example at Cousins, you have to click a box saying you are in the trade when you create an account - so this way if you order the wrong thing they are not obligated to take it back. It's up to you to know that you are ordering the right thing and they aren't going to help you figure it out.

Other places seem to embrace the amateurs - Otto Frei for example - they went after that market knowing what would come with it. It's probably why Bob is always in a pissy mood...😀

M’Bob thought you were referring to him when you mentioned Bob at Otto Frei
