I'm leaving it, the watch looks amazing out of the box and no one will ever see the gen in the wild or know the difference unless you travel to Dubai. I can't tell from the gen photos anyways how different the case is. Photos are very deceiving for all gens and makes. One would have to go to a store and study the gen in person in their hand to be certain after wearing and studying the rep for a while, anyone on here who thinks they know the watch so good can't be taken seriously if they are going by photos. Thickness I could care less about, the gens most likely to be seen by anyone in the wild are Rolex, Patek, a few AP's here and there, not RM, when is the last time anyone saw an RM in the wild?
The only thing I would consider doing is the crystal, but the gen has a blue tint to it, so have to see if that can be done first. It's just a fun watch to wear to take time off from AP's, but definitely super high quality.
