My 22 is a B-series L, which was an intentional choice as I didn't want the risk of wearing an T-dial. The 232 is indeed timeless elegance. I suspect that's where I will end, but seeing that 504 stirred up my interests as I do love that dark brown case / suede strap combo and would love a Lo Scienziato, PAM 350.
Can you please elaborate a bit more on the dos and don'ts? I do wear my watches so important insights. My understanding is that composite watches are much more durable than the PVDs, but maybe this is wrong.
