Fun fact: the "debug" app works just fine, the "release" (signed) version does not; obviously Google does not allow me to go live with a "debug" app / apk.
Please note that this is not the first or second release of the app; so I must insist that the whole jarsigner, zipalign, res/xml, res/raw procedure has been rehearsed a couple of times.
I finally got it to work on my phone and watch.
Here's what I had to do:
1) Uninstalled app from the Mobile Phone.
2) Restarted both devices (Phone / Watch).
3) Cleaned / Built / Signed / ZipAligned WearApp
4) Cleaned / Built / Signed / ZipAligned MobileApp
5) Turned Off Wi-Fi / Wireless on Watch
6) Installed app on the mobile phone.
7) The notification popped up on Watch, Install OK.
I am not convinced yet that all is fine though.
More than happy to leave these notes here if this helps someone else.
PS: I will carry on my investigations and try to break things again :)
