First, the finishing of the ROOS is many notches better than the highest end, limited ed Pam I've seen IMHO
Second, The movement though not in-house (JLC) is much finer and more detailed than the stock ETA which powers most of our Pams, again IMHO.
Third, The provenance and history of the manufacture is richer in history of watchmaking though the military background of the Maiale and Italian navy men is another story.
Let me add also that this site is exceptional. Lots of useful information and friendship tempered with RESPECT for one's opinions and passions.
Love and peace!
