Interestingly (or maybe it's just me :) ), now that I have a Record (supposedly a Record Pista) and a Centaur BB out and in front of me, the seals, such as they are, appear to be similar for both BBs. That is, a simple single rubber flange or seal on both. I can't see one being any more or less weather-resistant than the other.
Edit, in case helpful in future searches: the Centaur would put my chainline about 2 mm in compared to the Pista. So the Centaur came out and the Pista went back in...
