Tacky thing, ain’t it?
no, not tacky, a masterpiece of the metalsmith (gold smith) art.
The watch and watch case aside, the egg is fluted on the exterior but smooth on the interior meaning it is made in two sections that have been mated with perfect dimensional accuracy. Furthermore it was done twice, at the top and the bottom sections that are hinged together.
Then there is the stand cast from a different alloy that shows the great art and dimensional control that went into the carving of the wax models used in the casting process.
Although an overused term, awesome is a much better desriptive than tacky
