A sandwich dial is a layered construction of two or more discs where the bottom disc - or whatever is put onto that disc - is visible through holes/grooves cut into the top layer. This dial is a single disc with grooves cut into it, which have then been filled with gold paint or laid bare, depending on what the material is.
So not a sandwich dial.
@Omega world - perhaps you should be a little less aggressive towards others when discussing fairly irrelevant nuances when it is clear that you do not know much about the subject.
