.....the 5975 and 5575....all of them in my view have something which I love. That is, on the wrist, they look absolutely fantastic. I appreciate that there are horological issues at play too regarding movement size, legibility, usefulness of functions etc....I am not going into those....what I will say is that the 5975...in all metals just looks astonishingly beautiful on the wrist.....as does the 5575....just looks fantastic.
