My recently purchased 76100 came with just one 380b endlink on the 9315 bracelet. The other one is marked 580 which is not a perfect snug Appreciate help sourcing one to replace the 580.
QED The only difference to me is that the 580 end link is bent out of shape - if you or a watchmaker can bend it back into shape, it would look 100x better just my 2 cents
