It will probably only initially apply to the WATCH Sport users, but other than the actual shine (or comparative lack) of the material of the aluminum, the only noticeable physical difference is the colored crown. All someone needs to do is create a colored circle sticker or skin. Black, white, red, etc. If someone wants to take it to the next level, make a matching one for the below button as well. From afar, an aluminum WATCH Sport with a black dot could be mistaken for a stainless steel WATCH. Sell them for $2.99 with a manufacturing cost of $0.25 or something, and someone could make a killing.
