Hi,
I understand that the new offerings can let you thirsty, but they're not bad at all!
By the way, please let me try to answer:
Calatrava: I hope you've realized the 5159 calibre (5.25mm) is thicker than the 5153 calibre (3,3mm), so the case can't be the same! In fact i'm sure you know that! 
Of course you don't have to love, not even like the watch! Still for those who like the 5159 guilloche, they may like to see it on a more affordable watch, and indeed it helps create a family!
5960R: I'm not going to say it's just not molded, it's just because tou don't like pink gold I suppose. I don't like too much the 5960R either, but some seem to like it here, so the watch is good news for them! 
5101R: yes we agree! And the watch is not bad at all (even if I still prefer the 5101P, but who cares).
5098: Yes we agree even more, that's the one I hope to see end of April (although I won't have saved the money for the end of April).
Nautilus: I let the women answer!

IMO they have a very high reputation, but not the one of a company that makes the news every year! The Seal is enough for me this year! Let's get the new calibres next year! Yes new calibres please! (we shall talk about that soon).
I hope I helped you find some peace! 
Cheers
Dje
