The reason being mainly that the tapisserie is wrong for the model, based on the serial number.
The lume looks poorly done, and the PR fonts are very different from the others, and I don’t believe AP would ever make the numerals in the second time zone sub-dial that big, nor with lume.
It looks overall like a mishmash of ROO Scuba meets 15400, meets DT
I presume you bought this privately?
If not, then I would seriously consider going back to the dealer and getting a full refund.
