I have owned numerous 3120-based APs, and never a single issue of any kind. Still, even if it it runs perfect, I'm afraid you won't be happy with AP.
I am dealing with a similar situation over my Chopard. And actually the watch itself runs fine, but the brand really angered me, and so wearing the watch is not the same as it used to be. Very much a shame, all of these "luxury" companies should have a better understanding of who is keeping them afloat, and treat us with proper respect.
