Smartwatch: Google's Already Told Us What it will Be
There have been very few rumors or educated guesses about what the Google smartwatch will be like.
But here's the thing. With the Moto X and Glass, Google has already told us what how the smartwatch will work.
A smart watch must be able to permanently display time, sync in the background, show notifications, and have long (> 3 days) battery life. Sound familiar?
It is highly likely to be OLED. Because it needs to display the time constantly, OLED can turn on pixels selectively, displaying time without draining battery. And if we look at active display, the time can pulse can pulse in and out to prevent burn in. It offers great battery life but doesn't come at the cost of color or refresh rates (meaning no gestures or animations) like monochrome LCD or e-ink. The resolution could be 640 x 360 because Glass apps already use that resolution and Google would likely want to create synergy within its wearables platform.
The X8 has 2 super low power cores that handle voice and background tasks. Active display, notifications, syncing, etc. could all be handled by low power cores and the main cores only activate when the display is fully on. That would give a big boost to battery life.
Notifications could come in as active notifications and pulse in and out without lighting up too many pixels or activating the main cores. Since it's OLED, you could still tap to see the notification and drag to open an app.
It's no coincidence that Motorola has already made its own smartwatch. It had a lot of sensors to help with fitness and contextual info. Now those can be managed by low power cores and Moto's existing expertise can be put to use.
It just so happens so that Glass has a very simple to use interface that also happens to be mostly black with color where it's needed and lots of white lines. A mostly black interface would be very beneficial to an OLED display. Any Google smartwatch user would be able to move on to Glass without much trouble and vice versa (similar to what Apple does with the iTouch to iPhone). A timeline is perfect for a watch and Google Now means contextual info will be there for you more accessibly.
The Moto X has always on voice but it still requires that one take out the phone most of the time. A watch would always be on the arm and accept voice commands any time. Google wants to make googling a near reflex and this would be a perfect way to do it, especially with a low power core for always listening.
Google's no dummy. It knows what it's doing and it's been building the foundations for a smart watch right under our noses.

I know the concept art isn't that good but it's a quick sketch that gets the message across.
