By far the most important reason (but not the only one)
Again I need to talk about the 5070 but that is for me the most beautifull watch I know
I love love a simple rolex sub 16610 or a simple panerai or the very beautifull journe CS.
Breguet, Zenith, GP, Lange, Hublot, AP, JLC, IWC .... all of them have watches I like and I don't like (Patek also has a few I don't like)
But for me nothings comes even close to the 5070
Do I like it as much as the first day I bought it ?..........................NO
Everyday I have it i like it more and more
