Apple Watch branding is a hot, confusing mess.
Last year we had Apple Watch Sport, Apple Watch and Apple Watch Edition made out of pure gold.
Now there is Apple Watch Series 1, which contains last generation's Apple Watch Sport and Apple Watch lineups, except they are not the same, because they have a new chip.
Then we have Apple Watch Series 2, which contains the new Apple Watch Sport and Apple Watch lineups, except they are not called that any more, because Sports positioning is now lead by Apple Watch Nike+ Series 2, so they are simply called Aluminum and Stainless Steel, but they do come with the Sports band, which is not the Nike+ sports band, but the old one.
Finally we have Apple Watch Edition Series 2, which has nothing to do with the gold Apple Watch Edition, and costs a mere 1/20th of the previous generation's cost, and now only comes in white zirconia, like the Oura wearable, and only comes with the white Apple Watch Sport band.
