Just for what it's worth... the cases of the V1 SA and the V2 SA are definitely not the same. The V2 SA is commonly shown with gen dial swaps here on the forums, and it readily accepts the gen dial without removing the rehaut ring. The V1 SA, as The Zigmeister has informed me with parts in hand, requires the use of the rep rehaut ring on the gen dial to fit in the case. With the gen rehaut ring in place, the stem holes on the movement simply do not line up with the case holes.
So...
V1 - Accepts gen bezel, accepts gen dial only with rep rehaut ring.
V2 - Does not accept gen bezel, accepts gen dial with gen rehaut ring.
Plusses and minuses to both, therefore... Obviously on the V1 the dial depth is slightly inaccurate and you're stuck with the rep chapter ring. But the acceptance of the gen bezel is a big plus because this means you can actually remove and reinstall the bezel in order to remove the crystal for AR coating. Now, the V2 does have decent AR from the rep factory, however I don't know how durable it is and if it does get scratched then your SOL as that bezel just aint coming off without destroying it.
Just some things I'm learning the hard way.
