··Thanks, mystery donor!Someone recently asked me about the following 13ZN that is presently listed for sale. At first glance, I thought that the dial could be correct. I then checked one of my folders and noticed that a very similar dial and movement had sold on eBay in 2019. Given that black 13ZN dials are somewhat uncommon, I looked to see if the dials had any matching marks or deterioration. Further below, you will find two comparisons. The first highlights an imperfection on the right zero of "100" in the tachymeter scale. The second highlights deterioration on the minute sub-dial. To me, it seems likely that these are the same dial, but it would be nice to have better photos.
