As you might know, they used to Geneva seal the more refined variants of that movement (for example in the 1.96 but not the 4.96 of the Chopard Sport 2000) but stopped obtaining Geneva seals when they started doing QF. I would imagine that it certainly remains an option, and my only guess is that they haven’t continued it for political (and maybe economical) reasons. Perhaps someone else has a deeper knowledge of the thought process behind that migration towards a different certification.
Thanks,
