Vintage Omega BOR 11/511 two-tone bracelet ID Help Needed

I have a 1957ish Omega Connie that my Mom bought for my Dad ~ 1957 in Turkey. It originally came with a leather strap but sometime in the early 1960's he replaced that with a 5 bead BOR bracelet. and used it everyday for years. It is a tough watch and bracelet as I vividly remember him wrenching on cars wearing that watch.

He passed it on to me several years ago and I wore it daily for ~ 10+ years, but and since it was up for service again, I decided to send it back to Omega Geneva for a refresh. They offered to replace the much battered BOR bracelet (returning the original of course), but when it came back, instead of the two tone with 11 markings on the end links, it came back with 511 markings and in all gold plate. While nice, I was hoping that they would have duplicated the two tone Omega watch. I was told that they gold plate was what was available when the watch was new and the replacement two tone must have been later - thus the reason that Omega Geneva changed it. Not quite sure I believe that, but now I am on the hunt for a replacement two tone bracelet like in the attached pictures.

Any help ion identifying the Omega part number and leads would be greatly appreciated. Note: the last picture is of the watch after the Omega refresh with the gold plated bracelet. The other pictures are of the old bracelet that I am looking for.

Any help or guidance would be greatly appreciated.

Thanks. Good to know.

The old one had two issues - the end links were weak and the main clasp metal prongs were fatigued and constantly becoming loose (bending). The bracelet itself is ok. I kept bending the main clasp back to shape, but after 50+ years, I was worried that the watch would fall off my wrist one time too many and the watch would either smash to the ground or worse, I wouldn't realize it fell off.

What do you mean by weak endlinks? The loose clasp is an issue with most vintage bracelets. Tightening the clasp is pretty common. Another option is replacing just the clasp. Sometimes you can find service clasps online to swap the originals. Generic clasps can also be adapted to work; They aren't ideal, but it is a reversible modification.

Sorry for my poor explanation. Both the metal on the end links (on the edges) and the main clasp prongs have fatigued over many years and hard use, thus they have a tendency to bend very easily, even with everyday use and I have to bend them back each time. Of course, being SS, the more you bend them, the weaker they become from metal fatigue.

Here is a an explanation that you probably already know, but some may not???

From Wiki: Fatigue is the initiation and propagation of cracks in a material due to cyclic loading. Once a fatigue crack has initiated, it grows a small amount with each loading cycle, typically producing striations on some parts of the fracture surface. The crack will continue to grow until it reaches a critical size, which occurs when the stress intensity factor of the crack exceeds the fracture toughness of the material, producing rapid propagation and typically complete fracture of the structure.

After 50+ years, they are getting to the point I worry that the tabs will simply break off from one too many bends, thus I will definitely take your great advice, watch eBay, etc and maybe find some parts to replace those in question. Excellent feedback and ideas. I really appreciate you taking the time to help me.
