Another lost bracelet screw thread...

Yep, I lost a bracelet screw, darnit.
My closest AD is pretty far and i would rather just do it myself.
I have managed to decipher it's the part number 124ST3307 and i'm just going to get a few of these just spare for the future too.

I have these on ebay. just wondering what is the likelyhood these parts are fake? is fake omega screws a thing? Any help would be amazing.
I think these screws are real but would love your input.

Here's the link to the listing

I know the omega service center will sell some parts and maybe they will sell the screw you need. Call and ask before you buy only because I have seen many times parts for watches listed online at a price greater than you could buy from the service center or AD.

Thank you guys. I called the service centre and they have refused to do so without a "repair" so would actuallly be cheaper to buy the 90gbp one
