I've removed his name, but you can see that he validated my shift towards describing the caliber 1315 as a mechanically finished movement. My continued suspicion is that the 1315 and old Moonwatch sapphire sandwich caliber 1863 - which featured some glorious chrono component bevels - are finished to a shine by some kind of sophisticated equipment that's common within the Swatch group of brands. Now, it's possible that whoever answered this email neglected to mention a final pass with some kind of felt-tipped hand drill, but the clear intent is to describe the 1315 bridges as non-artisanal. I would rather be cautious and describe these movements as mechanically finished rather than over-sell a 1315 to a client on the basis of Patek-style decoration that may not be taking place.
