I used to get into the dilema between the RG and SS. I do believe that the RG are really really dressy and can also even match with jeans and T-shirt!! However, I love the old steel look so I pick the SS for my wrist.
Go to your AD, take a look and decide. If you love it, go for it. You will not go wrong with this 5712,
Cheers and keep us update.
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.
