I have always associated that problem with the size......
my wife is the proud owner of my WG PAM 062, which I remember was considered a BIG 40mm watch some years ago .... I had to go through Rads at 42mm (PAM065 Platinum) and 44/45mm (PAMs 163 and 190) to conclude - all too small.
That's why I was all over the two 47mm Rads, but now, after owning both I confess it's not the size. I just don't like Rads....
Still, not letting go of these two though
Cheers,
Asi
