My first (only!) Patek is a 5712 RG and I love it,sometimes when I check the time i have forgotten I am wearing it and it still surprises me how stunning it is,a little bit like a surprise reflection of yourself in a mirror,it takes a second before you realise it is yourself,the difference with the watch is it is a most acceptable surprise.
The watch is stunning,for what it is worth I have no regrets.
