So we have a ladies watch dated to 1927 w/ both case SN beginning with "7" and Square date symbol on movement, which is hallmarked to include "rolled gold plate".
I doubt something as simple as Rolled Gold Plate would not make this a Minerva, but I'm pretty sure all our ads for Minerva state filled or solid.
