Sony (then Sony Ericsson) has been making Bluetooth enabled watches from as early as 2006.
In 2010 the LiveView smartwatch was launched, featuring a colour OLED display that let the user view notifications and control the music player.
Its successor was the Sony SmartWatch in 2012, of which two newer revisions have been made since.

In 2014 a fitness tracking band, named SmartBand, was introduced.
The device's data is accessed using an Android application named Lifelog, which presents statistics about their everyday activities.
In 2015, a successor to the SmartBand was introduced, named SmartBand 2, which can track user's heart rate, movements, sleep, and the moments they are calm or excited.
