Fair rebuttal; we're meant to infer the left-side hand pointing at the watch belongs to the same model of the right-side arm that's wearing the watch. Admittedly, this is an assumption based on insufficient data. It's not impossible that the finger-pointing left hand and the watch-wearing right wrist are owned by two different models.

That doesn't change the fact that the watch is worn on a right-arm wrist in an orientation that would show it as upside down to a right-arm wrist owner.
