My bitcoins ended in a watch only address and now I cant move them out.
How did I do it:

I created a paper wallet with bitaddress, I saved the key. Then I sent BTC to that paper wallet from exchange.
I then created an electrum wallet and saved the seed.
I then created a new electrum wallet within the previous wallet, with key from paper wallet, a watch only address, then I swiped the paper wallet into this watch only address.
This watch only wallet is a deterministic wallet, i dont have seed/key. Bitcoins are now there.
Is it possible to retrieve key from the seed of original electrum wallet? Any idea how?
Thanks.
