Any watch with seconds at 9 (or 3, just invert the dial and the crown is on the other side) requires a movement that can do this, usually the ETA 7750 or 7753 or the Asian copy for automatics, and ETA 6497/8 (or Asian copy) for handwinds.
For the automatics, when an ETA 775x (or copy) is used, the chrono functions are unused, and those parts can be removed from the movement, giving a more reliable Asian 7750 for one thing. Using the 7750 with seconds as standard (eg. ETA 2836) means having the chrono seconds counter running constantly. What is the point of this when the cheaper ETA 2824, or 2826 (or Asian copy) is designed to do this already?
The date on this 48mm watch will be closer towards the centre in any case due to the watch diameter, so I don't think that's the reasoning behind it.
I agree with the questions about the need for a decorated rotor, the movement specified and the "white gold".. and I can only come to the same conclusions as the original poster.
