The following is an overview of a teardown analysis conducted by IHS Benchmarking.

IHS estimates that 50 million wearable devices for consumer use were shipped last year, and that the market is taking off, with 45% growth in unit shipments in 2015, after 15% growth this year. Smart watches are expected to have the largest impact on the wearables market, accounting for 33% of total shipments in 2019, compared to just 3% last year. The wearables space comprises more than 160 suppliers and 25 product types.

The LG G watch is the company’s latest entry into this rapidly growing and increasingly competitive market. It is the first LG product running the Android Wear OS, and must be paired with a smartphone or tablet running Android 4.3 or higher. Pairing is done via Bluetooth version 4.0LE.
