I have multiple of the WJean, the thicker one that isn't the sliding adjustment. They wear incredibly well, and are way less that the guy always touting German ones. They do not have a adjustment to them like you're looking for, but if you wanted you could I guess go get a clasp for a 3ooMM, but those are only in silver, not PVD. Other than the adjustability though, I think you'd love a WJean.
