Considering Purchase of this Constellation Pie Pan online

Good evening,

I am still looking for my first Omega (constellation pie pan).

I have found the below in an online auction and would be most grateful for the Forum's comments, particularly on originality of parts, condition and estimated worth.

I have been told the seller does not have info on its running accuracy and it is being sold by South America so will presumably attract import duties into UK.

Kind regards

In addition to previous comments, the crown might also be missing some of the gold plating
