Availability, last time I asked, was still somewhat limited in the US. Always some in stock, but not the entire line up.
Personally I own one, and in theory would own another. I own multiple Swatch watches and so why not multiple MoonSwatch?
From my consumer perspective this remains a fantastic product. A fun product.
There is nothing I see which makes me believe this somehow cheapens Omega or the Speedy. If you wanted to spend $10k on a Speedy buying a Swatch is not going to satisfy you. Most Speedy buyers are aspirational and only the real thing will ultimately satisfy them.
