As there are so many different dial categories. Just like for cameras and being a bit tongue in cheek I will say the best salmon dial is the one I have in my small collection, the FM Casablanca. Supposedly the dial does not have any UV coating and will patina over time.
I actually do not like salmon dials but this dial won me over and I think that is the ultimate test - if a salmon dial watch can convert someone who does not like salmon dial watches to owning one, it must be something special.
Does any manufacturer match their date windows background to salmon dial color? You'd think at this price level manufacturers would not just grab off-the-shelf white background date dials.
