And here it is on Angus' site,

Things I personally noticed are mentioned below. But note that the pictures are not the best and not the same size so it's difficult to say with authority for everything but just my observances.
1. AR seems different but the lack of quality pictures makes it hard to judge. It seems there is a lack of blue hue (that's not a good thing as gen IWCs do have a blue hue)
2. Day/datewheel is slightly bolder/thicker font than the HBB version.
3. The concentric circles on the V2 seems to be "tighter" and more of the rings such that they're not as prominent/sticking out. Look at the 6 o'clock subdial, you can see the lines running clearly through the numbers in HBB version but not so in the "V2". You can try to count the circles but it seems to me V2 has many more.
4. Not sure if it's the picture but the large numerals seem slightly thicker/fatter on V2.
5. Red arrow seems bigger in V2 as well
