Based on the other thread and this one, there are enough red flags to leave it well alone. You've pointed out the incorrect canvas bag, the odd caseback, and there are a couple of other things I'm far from thrilled with in the pictures you've shared on this and the other thread. Fakes of popular models in China are getting
exceptionally good now, to the extent even very good close up photos (and these aren't that good) can be very hard to spot. It makes me very wary parting with cash.
The NTTD calibre also beats at 3.5hz, though, which very few non-Omega calibres do - including super clones. The finishing still - as far as I'm aware - on the movements isn't going to fool anyone under a loupe, but since this is a solid caseback, it's a harder tell (and people who knowingly sell fakes aren't beyond sending you images of real calibres/timegrapher results). I'd walk away.
