Maybe third time 's the charm. Sony's first Android Wear device is smartwatch number three, and it's gone on sale today, priced at $250. There's no circular screen , but there is a healthy dose of IP68 waterproofing and a built-in GPS. Features like this could make the SmartWatch 3 arguably the most outdoors-friendly of the Wear crowd, even if its relatively meek design doesn't turn that many heads.
