Yes, you are correct that the end links do not fit the case (which came from Phong) perfectly. The end links did fit my old MBW case perfectly, but, unfortunately, the 1570 movement did not fit perfectly in the MBW case, which is why I replaced it with Phong's case. I could probably reshape the end links to reduce some of the slack, but, then, they might not fit onto my 1665 as well. In any case, the watch/bracelet looks ok on my wrist & the slight looseness (which is somewhat common to many vintage Rolex bracelets, especially as they wear & stretch) does not bother me enough to want to modify them
