I'll try...
I believe the 6002 has the base movement rotated roughly 30 degrees clockwise, such that the crown is relocated to 4 o'clock. Thus the tourbillon cage is now shifted to 7 o'clock (dial side). Maintaining a seconds hand at 6 o'clock will require an auxiliary geartrain to connect the tourbillon cage shaft from 7 to 6 o'clock, provided if there's even space under the moonphase disc for that.

of finishings than the one on the left. I wonder if it is because the 1st one is a kind of Ebauche and the other one a fully refinished movement ?
Both of these are finished movements, these watches were sold to customers.
Only 3 or 4 of the 1000+ of these movements Patek has made look like the left. These are just very, very early versions of the movement. This change happened in 1992, while Patek dropped the Geneva seal in mid-2009. Here's one with the better decoration a...
