Sony SmartWatch 2

The Sony SmartWatch 2, model SW2, was launched in late September 2013. The SW2 supports working together with any Android 4.0 (and higher) smartphone, unlike Samsung's competing Galaxy Gear smartwatch, which only works with some of Samsung's own Galaxy handsets. The watch features an aluminum body and comes with the option of a silicone or metal wristband, but can be used with any 24mm wristband. It is 1.65 inches tall by 1.61 inches wide by 0.35 inch thick, weighs 0.8 ounces and sports a transflective LCD screen with a 220x176 resolution. The SW2 connects to the smartphone using Bluetooth, and supports NFC for easy pairing. It is rated IP57 so it can be submersed in water up to a metre for 30 minutes and is dust resistant.[2][3]

At IFA 2014 the company announced the Sony Smartwatch 3.[4][5] Its processor switched from previous generations' ARM Cortex-M MCU[6] to an ARM Cortex-A CPU.[7]

As noted by ABI Research, "The SmartWatch 3 has many new features such as waterproof (IP68 rated, not just resistant), improved styling, transition to Android Wear, and introduction of a new wearable platform from Broadcom. ... [It's] based on the Broadcom system-on-chip (SoC) platform which includes a 1.2GHz Quad-core ARM Cortex A7 processor (BCM23550), an improved GPS and ambient light sensor processing SoC (BCM47531) capable of simultaneously tracking five satellite systems (GPS, GLONASS, QZSS, SBAS, and BeiDou), the now popular Wi-Fi 802.11n/BT/NFC/FM quad-combo connectivity chip (BCM43341), and a highly integrated power management IC (BCM59054)."[8]

Several apps are capable of using the Smartwatch 3's GPS, including:

  • Google MyTracks (since 2014, December)
  • RunKeeper (since 2014, December)
  • Endomondo (since 2015, March)
  • iFit
  • Ghostracer (can upload to Strava)
  • Strava (Beta)
  • Rambler

The watch is also capable of tracking swimming with swim.com and golf swings with vimoGolf.

The Sony SmartWatch 3 will not be upgraded to version 2.0 of Android Wear.[9]
