Patek Philippe 5100.
Finding some good pictures of the 5100 on the net is not as easy as we could think...
A pity, as it is a great reference which, strangely, didn't meet the success it deserves, though.
So here are two I found. ( Credit: Christies ).
The Armada, the four versions all together.
And the solo, the 5100P.
My favorite? The G, for once, because if its stunning blue dial.
