Hi Oliver
reason for this choice is opportunity, I was able to buy all of these at much more reasonable prices than list, some new (RM 011), other at auction, but always at a substantial discount vs. list.
in all fairness, my absolute favourite is the RM015, but that's absolutely out of my league! Although I keep scanning!
i did not start with RM, i love watches, followed courses in horology and love complications, i own Patek's, Rolexes, AP's, IWC's etc.., but I find that RM just blends in the technology, the horology and the modernity that makes me tick; i am also a car nut (guess that explains a lot) and a sailboat lover (hence the RM 015)..
