问题
I am trying to setup my development environment for Google Wear and have followed Google's instructions but as soon as I setup the port forwarding (adb -d forward tcp:5601 tcp:5601) I am getting an error on the device;
Connection closed, waiting before trying again
I have the emulator running on the PC and Android device is a Nexus 4, 4.4.4.

If you've updated everything, and have the new emulator, you might need Android Wear (not Android Wear Preview). Follow these steps: http://developer.android.com/preview/google-play-services-wear.html
You may have done this recently, but now that Google Play Services 5.0, and Android Wear is out (unofficially) it's worth trying again to get the latest updates.
OR, you may just need to click that emulator button in the screenshot, to let the app know you're connecting to an emulator.

One issue I found when attempting to do this 2 weeks ago, is that despite the documentation saying to save the image to a snapshot, the emulator will not connect when launched from a snapshot. Launch the emulator and uncheck the box for "launch from snapshot."
Once the emulator is running, run
adb devices
and ensure the watch emulator is showing and has "device" next to it. If it does, then you can run
adb -d forward tcp:5601 tcp:5601
Now try connecting the preview app.

The trouble I was having, was that the pre-selected API level was set incorrectly. It should be set to the following values:
Using Host GPU is optional.

Stuck with the same a while ago. It appeared that Google updated their Android Wear app - the one on the screenshot in the question is out-of-dated version. After installing new version everything worked for me (as long as I used device with android 4.3+ and adb -d forward tcp:5601 tcp:5601 command to connect to wear emulator)
