OMEGA 1125/560 FOIS Bracelet extra links?

I have an OMEGA 1125/560 FOIS Bracelet but it's too short and I could use some extra links. Does anyone know if there are reproduction links out there to fit this? Is there a source for the 15.5mm (?) sizing links that will fit this?

How old is the bracelet? The early versions use screw pins and the later versions use cotter pins. If you have an earlier version, you may be stuck hunting down orignals, which can be a little tricky to find.

are the later versions with the cotter pins available?

Thanks everyone. I believe my watch uses the cotter pin system. I've contacted the local Omega boutique. It seems there are not a lot of Omega dealers around which is surprising.

I took the watch to a watchmaker and it turns out to have the screw system. So I guess it’s off to eBay unless someone comes up with a solution.

I called Omega directly, the local boutique was not any help. I believe that the new and old links are compatible with the only difference being that one uses a split pin and the other one a screw. The bracelet just pivots on the screw or pin so it doesn't matter. The 114ST1125 should work on all 1125 bracelets.

It's super maddening that there is not a cross reference for all this stuff posted someplace. Omega pretty aggressively paywalls that information and I couldn't find anyone at the local Omega or even Omega HQ that sounded authoritative. They guess it would work so I ordered them. Apparently they are returnable.

It will likely work but you'll very likely destroy the threads in the original bracelet link where the new link will connect if you shove a cotter pin in the hole instead of a screw pin. I also believe the holes in the later links are smaller than the holes in the screw pin links. A standard cotter pin may not work.

I don't think there will ever be a situation where I am inserting a cotter pin into a screw hole. I think the added links just will use the cotter pin into a cotter pin hole. I guess I will find out when it gets here.

I called Omega USA in New Jersey and ordered some 114ST11621 links, these supersede the older 114ST1125 links and are the current part replacement for all 1125 bracelets regardless of end links or date of manufacture. They mix and match with the older style screw head type link because the cotter pin on these only ever goes into it's own link. These work fine on what I would guess is my old early 1970s era bracelet with screw head type expansion links.

The links cost $30 each and arrived in about 3 days. I would guess they shipped 1-2 days after I call and were shipped UPS ground, but I live close to NJ.

I am pretty happy with the result because I can now use my formerly too short 1125 bracelet.
