Hi, Kevin,
As for the rough look of the dial, yes, you shouldn't forget that these macors are quite extreme, but also that JLC wanted to give to this watch a retro look, and the material used for the dial contributes to this look in an old way.
As for these macros, I used the Leica for the pics of the watch, and a Sony DSC7 for these "extrem " macros.
Can't take macros with the Leica..Impossible!
Best.
Nicolas
