I certainly see your point, and this is a matter of aesthetic preference. That said, however, enamel is perhaps the most traditional way of finishing guilloché on not only watch dials but all sorts of high-end metal arts. My personal favorite example:I like the "Moon" part but I'm not sure about the dial, even in enamel. I think enameling is best done on a flat service that adds that rich depth to the dial. It may be lost here but it's probably a watch you have to see in person to tell.
Which is likely its ballpark. Maybe more like 25-30, but still.Its nice but not like 35-40k nice, lovely piece but for that money i would rather have a A.Lange or Patek..
