Apple has years of gray aluminum casted devices so production problems seem unlikely to be the reason for the shortage. I am starting to think maybe the Space Gray (even though an attractive watch) was not the eye catcher Apple wanted in the wild to start. This new part of business has all kinds of fashion marketing methodologies being sprayed all over it by the new retail guru. The SS with a white strap that TC was wearing on stage was surely test marketed and decided for a reason. A white strap grabs attention a gray watch with black strap does not at a distance of more than a foot. Even though gray has been a consistently more demanded color with previous with iDevices, the white strapped watches will create a larger forcefield of curiosity and envy. Isn't is how fashion marketing works? Get ready for Fendi and Gucci Apple watch straps!
