Moto 360 Sport watch goes on sale this month for $299

Announced in September, this health-focused Android Wear watch with GPS radio and AnyLight screen arrives in the U.K. and France this month, followed by U.S. availability in January.

Motorola revamped its Moto 360 Android Wear watch in September yet hasn't sold the then-announced Sport model. That changes this month with the Moto 360 Sport becoming available on December 18.

The $299 smartwatch will launch first in the U.K. and France, followed by U.S. availability starting January 7 both at Motorola.com and other online retailers. Three days later, the Moto 360 Sport will arrive in Best Buy retail stores.

Aside from the silicone sweat resistant band, the Moto 360 Sport has a few other key differences compared to the standard version. Motorola added a heart-rate monitor and its own Moto Body app to track time spent exercising in different target heart rate zones.

The Sport model also uses what Moto calls an AnyLight hybrid display on the round watch screen.

Similar to the transflective display on the Sony Smartwatch 3 I bought last year, the Moto Sport screen looks like a traditional LCD screen indoors but reflects ambient light while outdoors, helping to make the screen more readable without using more battery power.

And that should help the Moto 360 Sport last for a full day on a single charge with its 300 mAh battery.

Aside from that, the watch shares most other features and functions as Motorola's original smartwatch, running Android Wear and syncing data through its Bluetooth and Wi-Fi connections as needed.

There's also 4 GB of storage available to store tunes from Google Play Music so you can get your jam on during a workout, even when leaving your Android phone behind.

The Moto 360 Sport will arrive in three colors this month: Black, White and Flame Orange. Unlike the new Moto 360, which is available in two sizes, the Sport model has a 45 millimeter screen, so it's one-size-fits-all.
