A first look at the new Microsoft Band 2 (pictures)

Microsoft's new band, called "Microsoft Band," looks a lot like last's year model, but it now features a curved display for a more ergonomic fit. The screen is protected by Corning Gorilla Glass 3, which make it more durable and less likely to scratch.

The Band is a smart fitness tracker that is capable of displaying notfications from your smartphone and tracking things like steps taken, calories burned, distance traveled and your sleep at night.

The battery, which is said to last up to 48 hours on a single charge, has moved underneath along the clip-on clasp, instead of hugging the band's sides like the old model did.

An optical heart-rate sensor is also located on the strap.

There's also GPS for measuring pace, distance and speed when running or cycling, a UV sensor to measure exposure to dangerous UV rays, and an accelerometer and gyrometer for tracking steps and sleep. New this year is a barometer for measuring changes in elevation, such as the amount of floors climbed.

The new Microsoft Band will be offered in three sizes: small, medium and large.

You will find detailed information on sleep, workouts and activities in Microsoft's Health app and platform on Android, iOS and Windows.

The Band can also sync with numerous third-party apps, such as MyFitnessPal, Strava, LoseIt, RunKeeper, and more. There's even an Uber and Starbucks app on board.

The Microsoft Band 2 is available for preorder today and will ship October 30. The tracker will cost $249, a $50 premium over the original model.
