Things are simple: You have an Hard Core 47 mm Panerai Collection, and you must have it, with the Pam 191 ( Compass ).
If you don't , then pass on it, as it is unwearable, truely unwearable for the common mortal.
It is very nice but unless I have a serious 47 mm collection, I don't spend 19 000 Euros on a watch I won't be able to wear.
Wearing a watch is the mininum I require from a watch.
Aaah, if you want to dive with it, forget it, too, as its Water Resistance is 30 meters...From the beach.
Best,
Nicolas
