Cartier's hallmark on 10 or 7 hour?

[NU-ONE]

Hi all,

"Cartier" marked on the 7 or 10 hour?
It seems it's on the 10 hour on lady's or little watches (under 25mm approx) and on the 7 hour for bigger models....that's what I understand until now and I'm really not an expert!
Is an expert here ?

I'm not an expert, but I've observed the same thing, that the microprinted CARTIER in the Roman numerals occurs in different numbers depending on the size of the watch.
