I'm spinning this off of another thread running now, but it's something that was brought up and discussed a bit but I've not actually seen an example. Of course, 18 size OPEN FACE pendant set watches are quite common-to the point that lever set OF 1883 model Walthams are considered something of a prize to an '83 collector. With Waltham, you also see a lot of early OF 1892 models that are pendant set, along with later lower grades of 1892. Most other makers made quite a few PS OF 18 size watches after ~1900. If we discount N size Howards, though(which of course are not quite 18 size), I don't recall ever seeing a hunting case pendant set 18 size watch. In fact, every 18 size hunting case I've handled has used a set screw to retain the pendant. Does such a beast exist? I've come to believe that it doesn't, but I'm happy to be proven wrong.
