That's because they all sold the watch already lolto be honest the only reason people are afraid of SH is because SH movements (not necessarily this one) used to have issues a year or so ago. Its just a reputational thing, for now the only thing that can be said is that the movement is new and untested, just like the SA once was.
i so far have not heard any member actually owning the SH having issues. The ZF version itself is absolutely phenomenal with its case shape and dial/bezel.
