You can buy NOS online as per below. They’re expensive but these are original endlinks wiry the code stamped into the surface as opposed to the laser etched ones.
Thanks, Paddy. I did find these earlier, but the difference in price between them and the modern equivalent from Omega is quite significant: $150 more for a pair of the NOS. Is there any real difference in outward appearance, construction or functionality?
I expect the only difference is on the inner side. Managed to negotiate a discount on the price as I bought two pairs (recently). They do cost a lot more than the newer alternative but I felt I mightn’t get the opportunity to source these again!
