in my opinion. I like knowing I have a nice watch on but don't want or need everyone else to know I am wearing a nice watch. I like your comment about the grand complication vs a diamond encrusted watch. I too would go with the complicated watch given the choice. I have seen some watches that have small diamonds as hour indicators with no stones on the case, bezel or clasp that look nice, but I still don't think I would wear a watch with any diamonds. Too much bling is not a good thing
