To check if Android Wear package exists on system:

public void foobar() {
    boolean doesExist = isPackageInstalled("com.google.android.wearable.app");
}

private boolean isPackageInstalled(String packagename) {
    PackageManager pm = getApplicationContext().getPackageManager();
    try {
        pm.getPackageInfo(packagename, PackageManager.GET_ACTIVITIES);
        return true;
    } catch (NameNotFoundException e) {
        //swallow exception
        return false;
    }
}
