The seller certainly can’t do anymore damage to the back of the case by opening it up and getting a movement shot. And I’m a bit put off by the photo distortion around the lettering, and I’m not entirely certain the hands weren’t painted as opposed to aged lume?
I dunno... many folks here have been pleasantly surprised to buy a watch in better condition than the photos would suggest, but these are seasoned collectors. My advice to a newish buyer: bad photos + no movement shot = walk away
