I also created a "Watching only wallet" in electrum and put the address in it. Of course Electrum shows the bitcoin on the address. I realize this is nothing earth shaking. But wondered if I did derive the private key from the seed if I could "add" that to the watching only wallet to enable me to send the bitcoin out of it? I might experiment with a small amount of bitcoin of my own. Create a wallet. Move a small amount of bitcoin to it. Then open a watching only wallet. Create a private key from the mnemonic that I got from the first wallet and see if I could send coin out of my watching only wallet with that key? I'll let you know how the experiment goes.

You can safe yourself the time: you can only send Bitcoin when the private key corresponds to the address, not by adding any other private key to the same watch-only wallet. Bitcoin would be worthless if that would be possible.
