11305 is gold case, this one is 41301 (gold plated). The dials of UG are interchangeable as in there are no set rules as to what dial goes with which reference (but there should be no stark contrast i.e. a goldish dial like this should ne paired with gold or gold plate).
I think the dial and the watch Seems genuine it is just that the description of the seller is off (case is gold plated not gold which makes it less desirable than gold or steel).
There is another gold triple date but the case looks polished and one subdial hand looks like it might be wrong .
