Hi Arthur,
Thank you for sharing this possession with us. Now we are those possessed by this beauty!
Honestly if I was on the market today for a Patek Philippe chronograph I would go vintage, and would not even need a watch as beautiful as yours.
I love the 5070 and even more the 5170, but vintage PP chronographs are just perfect.
Congratulations on putting your hands on such a piece.
Cheers
Dje
