Thanks for the article.
I wonder if you would elaborate on what you meant by "the edges of the guilloché are smooth rather than sharp"? My knowledge of guilloché dials is relatively limited and it would be great to be able to distinguish between hand-applied guilloché and stamping/CNC. I just watched a lecture by Josh Shapiro and he mentioned that this C
lous de Paris pattern is the most common one to be imitated (stamped or CNC milled). He also mentioned that straight-line engraving usually has some sort of border or recess to cover the ends of the cuts. I noticed that this dial does not have such a border/recess. Below are a few examples of straight-line engine-turned dials where the patterns meet a straight line (either where the brand name is printed or another section of the dial). Maybe
@Archer or
@Tony C. can comment on identifying hand-applied guilloché versus stamped/CNC patterns?
