There isn't much variety in the Apple Watch world, which isn't surprising considering Apple dictates what and what doesn't qualify as an Apple Watch. But what it lacks in other form factors or designs it makes up for in styles, branding, and limited edition models. Last year, Apple hooked up with Nike to show that the Apple Watch isn't just a fashion statement but also a runner's best friend. This year it is doing so again but with a more muted style. Unlike the Apple Watch Nike+ and its neon highlights, this limited edition Apple Watch NikeLab embraces a less glaring appearance while keeping the same features that runners and marathoners loved.
