wmclartenf1,
Good choice!
As ex-moderator for Chopard and current moderator for Piaget, I am torn between their respective regulators. Thy are both in-house designed and executed manufacture movements. The Chopard LUC movement is a little thicker than the Piaget but still acceptable as it wins on power reserve with those quattro barrels (good Audi link there!).
They have completely different styling viz round vs cushion case.

I don't have a pictute of the white gold case and grey dial Piaget Emperador coussin regulator that I prefer, but here is one of the large moon phase model of the right colour scheme.
