With their diagrams, I sort of understand how that works, is there a video animation of how that works?
Next step is reading about perpetual calendar movement, interesting that a perpetual movement only has 275 parts compare to 316 parts inside an annual calendar movement.
While reading the specs, the moon phase is accurate to one day off in 122 years! Again, puzzled about how that works, found a blog post on that, 135 teeth instead of 59, but is his explanation of how it works in the movement right?
That grey dial is just lovely! I seriously considered a PP 5056P for a short while, a local collector was selling his. I don't really swoon over any calendar, be it annual or perpetual, but something about those grey dials ...

That catalogue is positively obscene. Having simple tastes, I'm sure I'm not stepping on anyone's toes if I just claim lot 2026 (PAM 80 with a white gold, reduced Radiomir case and blue dial) and either lot 2235 (a 60's platinum time & date PP ref 3514) or lot 2359 (a steel PP ref 3718A, time only with grey(?) dial and an extra ivory dial). Lot 2210 (Rolex ref 6066) looks great, but is too small I think, at 31mm.
