I think Ashley is right. It could be the "new 3135", minus whatever module is underneath it in that photo.
The Sky-Dweller has received ton of negative remarks on ΩF and other sites, and frankly, I don't think it deserves the hate. The design itself seems a very "safe" evolution of the DDII with added complications. Although the appearance is not particularly revolutionary or exciting, I think they're still going to make quite a few sales to the Rolex crowd. Over all, I find it much more classy than something like the YMII.
Personally, I'm not a fan of the off-center GMT ring and how it cuts in to the Romans. I'm not sure why they choose to display the full ring when a single viewing window would be far cleaner and un-clutter the dial.
Edit: Also, for the same price you could get a Patek ☕
