There are some clear highlights here: two aspherical elements, two ED glass elements, Nano Crystal coating, Super Integrated Coating, and a whopping 12 elements in total. The F-mount 50mm f/1.8 G, by comparison, has one aspherical element, super integrated coating, and just 7 elements.
None of this alone guarantees that the 50mm f/1.8 S would be a great lens, but it certainly shows that Nikon has gone all-out with their design choices. Nikon also advertised additional manufacturing tolerances upon the launch of the new Z system, so it should be pretty clear why the Z lens is $600 rather than $177.
Completing the list of important specifications are the 50mm f/1.8 S’s weather sealing and 9 rounded aperture blades, for potentially higher quality bokeh versus 7-blade designs.
