I need a pair of 524 end links. Have contacted three Omega Boutiques, without any luck.....

It should be 026ST524. I have never used this site, but they seem to have them in stock: https://hovigs.com/products/stainless-end-piece-1069-026st524

I agree this is correct part number. They are sold separately you need to ask for 2. The OB is clueless- you cant just ask for 524 endlinks but if they have this number they can order. I got these exact endlinks from OB in Naples FL- took about 2 weeks. They are very close to the original just a bit shinier. Good luck

Agree. If you give them this part number they should be able to order. I haven’t bought 524’s this way but did eventually get 640’s once I gave them the full part number.
