Pheew, glad you didn't sell the rest of your collection, including the 5088P! ;-)) (Not that I ever heard of someone who owns a 5212 as a first Patek, at least at MSRP! :-) And that strap is indeed a real beauty, lively yet elegant. Enjoy ;-)
If you have a reasonably good record with a specific AD, however, Iโd frankly advise you to show an interest for this beautiful reference...Wish you the best of luck!๐๐
