Officine Panerai

is there any way to find out which models were made with sandwich dials. it is hard to tell from pictures. are the sandwich dials considered more collectable

Painted dial is so hard & slow to make & very prone to rejects due to over-spilt defect.

just check the image-sections of the big search eningines to get multiple pictures of each model and study them. I like the L-dial as well, but in most instances, a sandwich dial is nicer.
