Samsung has already given us the Galaxy Gear, while Sony has the SmartWatch 2. So what about Google watch? Well here's everything we know so far.
Google watch release date
Android Police's Artem Russakovskii recently spoke about Google's watch in a Google+ post, telling us that the release date is set for October 31. He also says this will be the date we'll see Android 4.4 KitKat go live.
This could be a hint that the watch will be running the new OS, but as Russakovskii notes, he'd heard the purported release date some time ago and it could have changed within that time.
Google watch design
A filing with the US Patent Office from early May 2013 showed a "smart-watch with user interface features" - it sounds pretty clear to us what that might mean.
The watch, displayed in the illustration you can see at the top of this page has two touchpads on either side of the display face.
The patent says that you'll be able to use these to "pinch, stretch and scroll on a platform with limited space available for user input." This could mean it will interact with Google Glass.
It's possible that the watch will rely on a Google Now-style use of information cards.
Google watch features
There's obviously a big question around what kind of operating system the Google smartwatch will be running. Right now it's all guess work, but the fact that the big Google Watch reveal is rumored to be the same as Android 4.4 KitKat - October 31 - means we reckon it will be lifting a lot of the tasty new Android features.
One thing that the Google smartwatch is rumored to be going big on is Google now, which some sources reckon will lie at the heart of the watch.
If so, this means we could be talking to our Google watch - very Google Glass style, then - to check emails or see what the weather forecast holds. We expect this also means you'll need a phone that supports Google Now in order to take advantage of the watch's core features.
Google watch to be Motorola-built?
We've also heard that the Google watch could be manufactured by Google subsidiary Motorola Mobility.
Anonymous tipsters contacted Android Authority and claimed the watch already exists in a physical form and has been seen in its Berlin, Manchester and Google's Mountain View offices.
Motorola already has an exercise watch available, the Motoactiv. Could this give us any hints to the possible design of the new Google Watch or should we expect something radically different?

Watch out for the glass
The Motorola aspect is particularly interesting, though not all that surprising now that it's owned by Google – and that Motorola released its own smartwatch, the Motoactv, in 2011.
The same sources also state that the watch is "not a standalone device yet", claiming that it needs to be tethered to a smartphone to function properly. This part isn't so surprising given that Google Glass works much the same way.

Google watch name
As for the name of a Google watch, many are predicting that it could use the same name as Google Glass - in other words, it will be a Google Glass watch. We're not so sure about this, since we'd have thought it will be a totally separate and somewhat more consumer-orientated product than Google Glass is. (And yes, we know Google plans to sell Glass to the wider world too).
Android Police's Artem Russakovskii wrote on Google+ that the watch currently existed under the name of Google Gem. While the final name could well be something different, we have to say we're warming to Gem.
Rumors also continue to abound that Google will launch its own retail stores, although it will take some time to rival the all-conquering Apple Stores, of course.
The stores would enable consumers to get face-on with Google Glass as well as Android phones and, potentially, the Google watch.
