for PP, i would choose a men's Calatrava(maybe discontinued model 3919 as it's a classic). never choose a quartz PP.
for Cartier, I would choose baignoire as it's a classic. Cartier just launched their new version baignoire. But I like the old model much more. if u have a bigger budget, buy Crash, it's a very special and nice watch. It's a discontinued model. Actress Yuen Wing Yee ordered one from Cartier not long ago and Cartier specially made one for her again at 1m. Baignoire Allongee with diamond bezel also looks very nice.
Rolex- no comment as rarely check out Rolex watches.
