 This is the new Moto 360 Sport watch. It's a sportier version of the regular Moto 360 Smart Watch 2, which came out earlier this year. This sport watch costs $299 and it starts shipping in early January. But at first glance, the two watches look strikingly similar. They both run on Android Wear and have the same round face, the same touchscreen display, the same flat tire, and the same single physical button on the side. And they even use the same wireless charging dock. So what are the differences between the two watches? The first thing you'll notice is that the sport watch has a silicone band that, unlike the bands on the Moto 360, can't be swapped out. It's a comfortable, sweat-proof band, but the downside is if your strap breaks, you likely can't replace it without replacing the whole watch. The second thing you'll notice is that the default face on the sport watch shows your daily goals, steps, calories burned, and has a shortcut for starting workout sessions. Although like the regular Moto 360, there are more than a dozen other digital watch faces you can use if you'd prefer those. Also, the display on the sport watch has a different hybrid display technology called AnyLight. It's a cross between your usual backlit smart watch display and a frontlit reflective display so that you can see it even if you're out running in bright sunlight. Like the regular Moto 360, the sport version has optical heart rate sensors that read heart rate through your wrist. Yet the Moto 360 sport watch has built-in GPS, which the regular Moto 360 doesn't have. And the sport watch includes one specific workout app called Moto Body Running. The batteries on the Moto 360 sport watch and the regular Moto 360 smart watch are the same size with the promise of a full day of life with mixed use. But it's safe to say that if your workouts are super long and you're using GPS during that time on the sport watch, the battery life on that one will drain more quickly. So the idea here is that the regular Moto 360 is something you'd wear throughout the day but is not really meant for workouts, whereas the Moto 360 sport is meant to be the kind of watch you'd wear for workouts and then still could wear throughout the day. That's really cool in theory, and the Moto 360 sport is definitely sportier. But it still feels a little like the same smart watch with some workout features thrown in rather than a full powered sports watch that could compete with something like a multi-sport garment. Which means that maybe right now the perfect blend of smart watch and workout watch still doesn't exist.
