Several more points worth noting. The actual crown position and engraving comparison. I would not say that the engraving of v2 is ALWAYS better than v1. See the comparison for yourself.
Caseback engraving on v2 is totally wrong on the inside. It has wrong model number and does not match with the actual serial number on the outside. See it for yourself.
I am also leaning towards v1. The v2 crown has too dark of Ti colour, IWC never uses such material making it a dead giveaway.
Missing caseback gasket on the v2:
This is a big no no... Water can easily penetrates inside. However, I have to give credit to v2... The caseback dust/antimagnetic cover. Lovely... It's made of real titanium.

Caseback comparison:
Refer to the respective serial number... v2 has wrong inner engraving.
