Weight and dimensions
The Smartwatch 2 is thinner and has more of a squared shape compared to the rectangular Galaxy Gear. Sony's device measures 9mm thick and 42mm by 41mm against Samsung's 11mm thick and 37mm by 57mm, which means the volume of the SmartWatch 2 is about a third less than that of the Galaxy Gear, but the Sony watch weighs more: 122 grams compared to 74 grams.
It's no use studying specifications if the device won't work with your phone — both have limited functionality when they aren't paired with a smartphone. Sony's SmartWatch 2 will happily play with any smartphone running Android 4.0 but Samsung's is much more picky. At launch it will run on the Note 3 only. Samsung said it plans to offer software updates to some recent model smartphones, like the Galaxy S3, but don't expect to use it on non-Samsung products.
Price and availability
The Galaxy Gear will be available beginning late September for around US$299. Sony hasn't announced a date for the SmartWatch 2, but it's listed on Amazon U.K. as shipping next week for £160 (US$250).
