Well quick set for the date rules 918 out. So what is left is 912 or something
new. Would 912 fit into a 42mm case? I think 912 is about 36.5mm wide, so
that could be a problem. Also: why would we need a perforated caseback con-
sisting of two parts for better resonance when the gong is fitted to the side of
the case? So my guess is: a new movement!
