There's no high end version of the latest SFSO (the one with the arrow seconds hand). Yours look well finished so I opt for the gen option

The pearl also says it's probably a gen, as the pearl on the rep has a larger surface of lume.
The almost white lume tells gen, although this is easy to mod.
To check definitely, you can open the caseback : the movement must be nickel plated and has the Breitling markings on the rotor, whereas the rep (with nickel plated ETA movement) has no markings.
That just reminds us how good the SFSO reps are.
This model of Breitling box has also been very well replicated
