Surely a collection for a wealthy owner, but even more certainly for a man of very very good taste ! I love them all, but the WG is killing me with its blue dial ;-) And for the Pt one, there is no word in my vocabulary but WOW ! Good luck for getting one...
Gorgeous 5100's ! The white gold version would already be enough for me. But if you can own the 4 of them, you deserve my greatest respect ;-) Best, D.
