rep could come earlier than gen
I know, it very well may! Sometimes they have in past indeed!
But do keep in mind thats why AP sometimes announces something, puts press release photos out, etc - then changes a few small details when the actual watch is physically released.
For instance, the Ceramic Divers. Remember the all BLACK hash marks in rotating inner bezel? The true watch ended up only having WHITE ones!
So, V1 rep was incorrect. I think it was updated by V2 but may have not been till V3. This is before they were even ceramic, when the case was DLCd or PVDd steel. I had one.
There are other instances as well...
Anyway, I'd much rather have a rep based off an actual, physical (presumably bought by the maker) watch - then a rep made off some marketing photos (because that one may turn out to be incorrect...)
