During the Google I / O, one of the expected topics were smart watches that will use the operating system from Google, especially changes to wearable devices, Android Wear. In the front line are the LG G Watch, Motorola Moto 360 and Samsung Gear Live.

LG G Watch

Watch with a simple appearance, lower resolution (280 x 280) and a battery of 400 mAh, larger than the Samsung Gear Live of 300mAh. In principle, the battery can last 36 hours. This smartwatch is available (for those who want to order in advance) from today. Price: 229 USD

Samsung Gear Live

With AMOLED screen of 1.63 inches, higher resolution (320 x 320), will be compatible with any smartphones and tablets with Android 4.3 or higher and comes equipped with heart rate sensor. The design is more elegant than the LG model, but Samsung does not disclose how many hours of autonomy will the battery. It is also available in pre-sale. The price: 200 USD

Motorola Moto 360

For now the hardware Moto 360 is still a mystery, Motorola has not released the battery life, performance, storage space, much less the price of the watch smartwatch. Rumors point to the final price of 249 USD (or more). The design is lovely, but while other features are not disclosed, it is difficult to advocate the cause of this smart watch.
