Thank you very much for pointing that thread out!
According to the old thread, member Kong had asked Chopard about the jewel count. Regarding the answer, to quote,
"Actually only 29 jewels are used. The additional was 'decoration'!
The Cal 1.96 after 2003 (from the COSC cert) should have the actual 29 jewels marked."
So the 3 "extra" jewels in calibre 1.96 were not functional? If this is the case, how very odd!
I wonder where those jewels were located, and how - or by what - they were replaced in the 96.01-L. At least the jewels are not visible from the back, as the movements look identical (save for certain engravings) when looking through the display back. So if they were intended for 'decoration' purposes, it was decoration for the sake of itself and not so much meant for the wearer it would seem.
