PRE-V is conventionally called the historical form of hands 6497 PANERAI, which was used in the PRE-V period.
Later, hands of a slightly different shape and design began to be used, they began to be called modern, in fact, from the PRE-A period.
Indeed, later, for different models in different ways, but mainly in the region of 2008-2010, on 6497 models became again put PRE-V hands, which differed from the historical PRE-V, but for the most part, similar to them in tip shape, longer than the lume strip, although the design is somewhat different, and the proportions.
At the same time, on the HW manufacture models, on the P.5000, P.6000, such as conditionally, PAM911 or PAM1085, "Modern hand" has remained to this day.
Here is a sample photo of the current PRE-V hands:
But this is usually called Modern:
This can apply to both gold and polished hands.
This is how the difference might look on the dial:
But in general, this is a story only about the HW models in the bettarini case.
Different models should have different types of hands. Long cycle models like PAM005 or PAM111 may have different hands depending on the series.
Panerai boutique editions are supposed to have PRE-V hands, like all HW PAMs on 6497 at that time:
but HWF used the modern version all over the place to unify them with the PAM1085 (which has polished but also modern hands).
This error has occurred in factories before (especially in the series, when pam000 / 005/111 switched back to PRE-V hands), and in modern models, such as the PAM911 from NOOB, where it is already just a way to unify and save.
The good news is that any hands can be bought from suppliers such as Jakson, Helenarou, Getat, Dsn and those who are currently working with them.
It is important to be careful to match the hand lume to match the dial.
