The SmartWatch 2 is the sequel to last year's Sony SmartWatch. The new model has a 1.6 inch touch display with a 220 by 176 pixel resolution. The display is also transflective, which should allow much better battery life. There are no speakers, microphone or camera like the Galaxy Gear, but the lack of these features should contribute toward a better battery life, which Sony claims can be between 3 to 4 days. Much like most of Sony's recent hardware, the SmartWatch 2 includes IP57 certification for water resistance.
Sony has really improved the overall performance of the device along with the interface, but the SmartWatch still lacks a selection of 3rd party apps. While Sony has been working hard to promote the SmartWatch to developers, it is hard to gain much use out of this device, other than using it as a second screen for your smartphone or tablet.
