Nv research much lei, was looking for a 5711 back then cos i didnt know how hard it was to get one.. then led to the AP lol.
Nevertheless the royal oak is a very good watch for fengshui. As are the Patek 57xx, 516x etc. Theres the whole story about how Gerald Genta was partially influenced by the octogonial taoist/buddhist symbols while in Asia. Highly unbelievable but a charming tale anyway.
Plus, stainless steel watches have proven to hold value pretty well for the most part of 5 decades.. I also bought a 7118 for my partner on the same trip, and the collective value of these two watches (the 7118 for the most part), has risen well over 20% in the span of less than a year.
Sure the bubble may pop someday but you know, let the good times roll.
