Now, if you happen to like a bit of life on your dial and you prefer the scratch-resistance of sapphire to the warmth of Plexiglas, then clearly the 422 is made for you. Kudos to Panerai for giving us both options.
For me, however, there is no question that the 372 is the best contemporary Panerai extant and addresses every need I have from this brand (just the time, thanks; no seconds, GMT, chronograph, power reserve, etc..). Honestly, I have no need to purchase anything else in their current catalog. Vintage is another matter, but I'm gonna need a fatter wallet to make that happen.
