How to fix Omega Constellation bracelet?

[Chaotik]

My wife has a really small Omega Constellation rep that I got for her just last month.

Yesterday while she was shopping, 2 of the links detached themselves and the watch dropped to the floor as a result.

Thankfully, it is a quartz and there is no apparent damage to the watch itself however, she did not pick up the ping that was holding the 2 links together.

I just took it to a place that has adjusted rep bracelets for me in the past but the guy told me the Constellation doesn't use pins but rather really specific screws that he did not have in stock.

He suggested I take it to an Omega AD and they'll be able to fix it... I'm sure they will.. but unfortunately, this is not really an option

I actually ordered a starter toolkit from fleebay recently and I should receive it any day now. However, I still don't have the darn screw.

Do you guys know where I could find this ?

Thanks
