We just got our second smartwatch — LG G Watch R (W110). It is one of the two round watches available in the market. And this one has passive OLED display, which means, it can be put in the active mode — display is on all the time. But it lacks an ambient light sensor, so you need to play with the active and passive brightness settings to get comfortable feel for all lightning conditions.
I recommend app called WatchMaker. There you can use one of the standard watch faces, or create custom based on preset. Because all watchfaces was somewhat bloated, I created very minimalistic one for me. See the last photos in the gallery. BTW, I paid for premium features (whatever that means).
Just got hands on brand new Motorola’s smartwatch – Moto 360. It is one of two round Android Wear smartwatches. This one has Dark stainless steel case with Black Horween leather strap.
So far, on low usage it lasts almost 48h on one charge. Currently charging only every other day. Also, the original Motorola App “Connect” only allows to select watch faces from the build-in vs Android Wear App from all watch faces.
