Agree the 3940 seems to be getting a lot of publicity these days, but thankfully not as crazy as the Nautilus or Aquanaut 😂
What you say re polishing is consistent with what I heard from the PP service center here in Hong Kong as well. Hence my preference for beat-up but unpolished over clean but polished examples. Does not help that resellers/auctioneers sometimes use dubious methods to ‘clean up’ their watches for sale. I’m always suspicious when a 20 y/o watch looks so shiny 🤨
