The LG G Watch R is a smartwatch with a smart round face, hence the use of the letter 'R' in its name which is intended to stand for 'round'.
As far as its core specs go, the LG G Watch R is essentially identical to the regular G Watch. It is equipped with a Qualcomm quad cortex processor that runs at 1.2 GHz, and offers 512 MB of RAM. It has an IP67 rating for submersion in water up to a meter deep for half an hour. The 410 mAh battery is a subtle upgrade over the regular G watch.
The main difference between the LG G Watch R and the regular G Watch is its display and build. The G Watch R has a plastic OLED display with a 320x320 resolution screen that takes up all of the watch's round face.
The watch will be available towards the end of the year; LG has not revealed pricing details yet.
