The Moto 360 is for me the more elegant decision, but the LCD display (not completely round and consumes more energy) the smaller battery and the bad CPU got me on the LG GR.
The AMOLED screen and the automatic white / black dimming function is great and looks very good. The battery is despite strong usage in the evening 40-50% full. The OS runs smoothly without reboots or quirks. The processing of the clock is very good. The bracelet does not look cheap and I will not change it. The clock is not too chunky and not too thick. Even I as a "non-clock support" got used to very quickly at the clock.
The display is large enough, however, might like to be a bit bigger. The edge protects the screen, but the margin could be reduced in the next version. The charging station is magnetic and the clock "clicks" automatically in the correct position.
The OS is the beginning of getting used to but you find your way quickly. The Apps are still in the development phase. They all work perfectly, but the functionality is still expandable. (Eg more Antwortmöglichenkeiten at WhatsApp etc.)
I could not find that the battery of my phone's is widely used. Maybe at the end of the day about 5%.
Currently I create my own Watch Faces of the clock, the pre-selection (about 24) is very good.
For the work I synchronize my calendar is with the clock around me to remind you of appointments and selected meeting rooms.
Please just let me know any questions!
