If I am honest, neither of these appeal to me.
I prefer the regular double balance openworked models by a good bit over this one.
For perpetual calendar, similar thought as M4. I prefer a solid dial for legibility. I still have trouble reading the small indicators with my eyes, so a PC is not a watch that typically interests me anyways (but I still love good photos of them!).
As for BMG on APs, I think it looks fabulous on certain models. Like the Jumbo with dark red dial, that one was fantastic. A bit too shiny on these open dials, IMO.
