Rolex B295C V3 V4 V5 differences?

[0nly5iv3Digits]

So It's come to my attention that Rolex no longer produce the B25-295C crystals. They are now exclusively producing the 7035's, which have a different crystal proportion/edge profile.

I have managed to scratch the crystal on my 16570 polar... wife's wedding ring whilst at a party...

Anyway, I have the opportunity to pick up a blistered 295C.

My question is as follows:

What is the difference between the B25-295-CAR-V3,V4, V5?

I am hoping to have a crystal profile that is the same (dimensionally) as the original B25-295-C2 that is currently fitted to the watch (F Serial EXP 16570).

Any guidance would be much MUCH appreciated.

Cheers!
