Apple Watch has come a long way since it was first introduced in 2015. Today, we met the culmination of the last two years (has it really only been two years?) in the Apple Watch 3.

This is Apple's first LTE connected smartwatch, though there's also a standard model that lacks LTE. Both are available for pre-order on September 15, and go on sale September 22.
