The G Watch R is the first truly circular smartwatch, and it's also the first to ship with quite so many watchface options - 18 in all. Here's every one, in both active (as in, the display is turned on and ready for interaction) and always-on (passive sleep) modes.

Left: Castle white, right: Red

Left: Hiking, right: Fitness

Left: Photos, right: Increment (like simple, but shows notification counter)

Left: Simple, right: Planetary

Left: Rings, right: Coordinates

Left: Dashboard, right: Reveal

Left: Digitalog, right: World clock

Left: Number, right: Moonphase

Left: Sapphire, right: Camping

So, there you have it - that's a lot of watch faces. Some of them have secondary information functions, too. World clock displays a second time in a city of your choosing. Number gives you the date and day. Moonphase shows the phase of the moon. Hiking displays your altitude and steps taken, and Fitness does too. Red, for whatever reason, shows the month.

I use Castle white.

Update: Not 20 minutes after I posted this, my G Watch R decided to get an update to Android 4.4W2. This update added six new watch faces, pictured below.

Left: GMT, right: Aurora

Left: Club, right: Dress

Left: Needle, right: Record
