Differences between p.2002 and p.5000

[dj1809]

This question came up while I was reading about various PAM movements, in particular two of the manual wind 8 day power reserves. I did a bit of digging and this is what I could come up with:

p.2002
- 247 components with 21 jewels
- 28,800 oscillations per hour
- 6.6 mm thick, 13 3/4 lignes diameter
- GMT function
- Quick hour set
- seconds reset function
- 3 spring barrels in series

p.5000
- 127 components with 21 jewels
- 21,600 oscillations per hour
- 4.5 mm thick, 15 1/2 lignes diameter
- variable inertia balance

So it looks like the p.2002 is the more "complex" of the two movements. It appears though that the p.2002 is not simply an advancement in the p.5000 but a completely different architecture.
