very grateful for such varied and truly informative replies. Obviously very topical and contentious.
Visited 3 ADs whilst on visit in london, england & they truly are awashed with 5146s including that absolutely stunning 5146J with matte slate dial. heavily discounted on these as well as PCs, but more forthcoming on the ACs.
I am going to put them on my wrists in different lights and then see which kind of shines out to me, i guess.
i do wonder in terms of craftsmanship and workshop time, how much more is involved with the PCs vs ACs; as you can see, i'm truly ignorant on all aspects of watchmaking although i do own a range of them - chosen according to how i like the look & feel of them (!!) as well as their pricings.
