I can't speak for everyone, but my hope was that this dial would provide the most accurate replica of the original Cali. I'm not sure your post is suggesting that the DSN (or other rep dials) were copied from a gen dial? It was my understanding, however, that the 262 Radiomir was in fact patterned by Panerai from an original 3646 Cali dial, and so therefore a dial that's built from a gen sample of the 262 will have the best chance of hitting the original Cali dial as well.
If this is an incorrect assumption, please advise. Thanks.
