I looked through my technical manuals and online.
It seems that the 5M85 is the improved version of the 5M65 with the base movement unchanged.
Therefore, its probably the same amount of jewels which is 6 jewels.
The only difference from what I know for now is that they changed the capacitor in the 5M65 to a LiIon battery in the 5M85 , which in their opinion has better charge retention (6 months reserve), better lifespan and of course, cheaper to replace than the previous capacitors.
If anyone has more information, do share.
