I have a gold(?) watch with the maker's mark of S.A.D. inside a shield. The mark is on the inside front cover and on the movement. The shield on the cover also has a crown above it. There is also an eighteen with a crown over it on the cover.
Does anyone know who S.A.D. might be?
I would appreciate any information you can give me.
