Should an android wear app self-install from Eclipse?

I have developed an android wear app and corresponding mobile app (as per http://ift.tt/1q2PWVc) using Eclipse. My cell phone and wearable (Zen watch) are of paired over Bluetooth and working fine. I attach my cell phone to my development PC via USB (with debug on). By running my cell phone app from Eclipse, selecting the hardwired cell phone as the target device, should the wearable app install on the wearable device (assuming I packaged it correctly)?
