From the start the Moto 360 has been one of the more popular Android Wear smartwatches out there, and the updated Moto 360 2015 hasn't slowed its momentum. But the decent leather or steel link bands that the 360 ships with aren't exactly what we'd call "fitness friendly". So there's now the Moto 360 Sport, an iteration on the 42mm-sized Moto 360, but with a design that's a bit more attuned to taking a beating.

The differences here are many, at least on the outside. On the inside the 42mm Moto 360 2015 and Moto 360 Sport are practically identical. The same 300mAh battery, the same 1.2Ghz quad-core Qualcomm Snapdragon 400 processor, the same 4GB of internal storage and 512MB of RAM. Chip-wise, there's little different. Though this watch does pack a GPS chip inside, so you'll be able to engage in run tracking while away from your phone. Instead of a standard LCD, Motorola's using an "AnyLight Hybrid Display" that's supposed to perform better under sunlight. Design-wise, however, there's a lot different here. The display here is, as before, 35mm in diameter with a resolution of 360x325, with the black "flat tire" bar underneath for the ambient brightness sensor. The display itself, though, is different. Instead of a standard LCD, Motorola's using an "AnyLight Hybrid Display", a screen that's said to work both as a traditional backlit screen and as a front-lit reflective one (think old school color Palm PDAs) for use in the sunlight. Unfortunately, the sun hasn't come out from behind the clouds here since we received the Moto 360 Sport this morning, so we'll save testing that for another day. That screen is covered in Gorilla Glass 3 and surrounded by a ring of metal — the inner half is a smooth matte metal finish, while the outer half is polished and etched with radiating lines. The two-finish effect helps to minimize the size of the bezel, and is something Motorola learned in designing the first and second generations of the standard Moto 360.
