The Sony SmartWatch 2, model SW2, was launched in late September 2013.
The SW2 supported working together with any Android 4.0 smartphone, unlike Samsung's competing Galaxy Gear smartwatch, which only worked with some of Samsung's own Galaxy handsets. The watch featured an aluminum body and came with the option of a silicone or metal wristband, but could be used with any 24mm wristband. It was 1.65 inches tall by 1.61 inches wide by 0.35 inch thick, weighed 0.8 ounces and sported a transflective LCD screen with a 220x176 resolution. The SW2 connected to the smartphone using Bluetooth, and supported NFC for easy pairing. It was rated IP57 so it could be submersed in water up to a meter for 30 minutes and was dust resistant.

Several apps are capable of using the Smartwatch 3's GPS, including:
The watch is also capable of tracking swimming with swim.com and golf swings with vimoGolf.
