I've gone through the same issues using Eclipse and the answer to my problem was following link that I've found:
http://blog.benjamin-cabe.com/2014/07/04/how-to-setup-eclipse-for-android-wear-development

WatchActivity:

just don't use WatchActivity - use standard Activity instead.

The import android.support.wearable cannot be resolved:

First step is to make sure that you have installed a Google Repository Extra in your SDK Manager. It should be located somewhere below the Android Support Repository

After downloading the Google Repository:
In Android Studio you just need to add a dependency for wearable-support lib like done here: https://developer.android.com/training/wearables/apps/layouts.html#UiLibrary.
But if you want to use any class from android.support.wearable package from Eclipse it is a little bit tricky.

Wearable package is not included in standard android-support library - you need to use wearable UI support lib located in google repository: com.google.android.support:wearable
Unlike the standard android-support libs, this one is not provided as a .jar file or project code that you can import right to your workspace, but it's in .aar format (like jar but also including res).

Please find this file here, relative to your sdk folder:
./extras/google/m2repository/com/google/android/support/wearable/1.0.0/wearable-1.0.0.aar

1. Unzip wearable-1.0.0.aar file somwehere to your workspace (you can see it looks almost like a standard android project)
2. Move classes.jar to /libs/classes.jar
3. Now you have to create new project from these files, with package name defined as android.support.wearable
4. Compile it with API 20 and select "Is Library" in project properties
5. Add reference to this library project from your project

I recomment you to take a look at this blog post. There is everything explained well step-by-step. If you will have any project feel free to ask in comment here.

You can disregard the WatchActivity compile error, see my answer here: https://stackoverflow.com/a/24463815/592153.

If you can't find android.support.wearable, make sure you've followed step 4. in this guide: http://developer.android.com/preview/google-play-services-wear.html

You can find the wearable library inside Google Repository folder. On how to extract and use it, you can refer to https://medium.com/@tangtungai/how-to-develop-and-package-android-wear-app-using-eclipse-ef1b34126a5d

Hope this help
