The minimum cost for an Omega watch is around $5,000. The Moonswatch that we're talking about here in this discussion is a Swatch. It may additionally have the Omega name on it, but anyone and everyone knows that it is a Swatch, produced to normal Swatch standards, on a Swatch assembly line. It has nothing to do with the line of mechanical Omega watches besides having the name on it.
The existence of an officially licensed Porsche toy car does not degrade the value of a real Porsche. Same for this Swatch.
