Welcome to the forum babalui! In my experience, most rep movements are fairly reliable in general. They all have their idiosyncrasies, but many of the rep movements have reputations of being very hrd to kill. Plus, there are MANY different movements used in Panerai reps, from very inexpensive 21j movements that cost $20, to swiss ETA movements, and just about anything in between. As far as basic watch construction goes, the newest generation of PAM reps are VERY well put together and should last years without any problems. Plus.... They are getting VERY close to gen in design accuracy.
