Ah yes, these rare handcrafts from PP are a special breed. I only have the 5231J which I'm super happy already, maybe someday I'll get one of those 5089s.
I know your 3448 and 5970R are one of the best, this side of the extreme. I am also happy with what I have, not many watches will make me feel butterflies in my stomach nowadays...maybe it's time to wind down.
