I am not sure if this topic has been discussed here before? Original Longines metal bracelets from the fifties and sixties seem to be rare. We know that some Conquest models like the power Reserve were available with such straps. Also the first Longines diving watch Nautilus from 1959. Two of them are marked JB Champion on the back. I can't find any manufacturer's mark on any of the other straps. For which models were these straps originally produced? Who were the manufacturers? Thank you for your input!
I had the second from the right come on a 9024 reference Conquest, and I’ve seen the Nautilus bracelets come on 900* refs, 902* refs, and 904* refs. Endlink shapes are different across the refs, though (at least between 900* and the others). I’ve always wondered myself what the one on the far right came on.. Nautilus bracelets - note the middle endlinks fit much better than the other two. And what the original Nautilus bracelet box looks like.. at least the ones with the sliding clasp.
