You will need the Apple ID and password as mentioned above, or the original Watch purchase receipt showing serial number (or IMEI, if cellular) and a discussion with Apple Support. Activation Lock is intended as a theft deterrent, and is intentionally difficult to bypass. We can’t help bypass, and Apple—absent sufficient proof of ownership to convince them—won’t help.

Your iPad will be Activation Locked to the AppleID username (email address) and associated password that were last successfully used to setup the iPad. As such, you’ll need to recover these credentials if you are to successfully reuse the iPad. If these have also been forgotten, they can be recovered here:

To recover your credentials, you’ll need access to one of the following:

• Your primary email address mailbox that corresponds with your AppleID
• Any of the secondary/recovery email addresses that should be configured for your AppleID account
• Any of the trusted telephone numbers (fixed line or Cellular/Mobile) that are associated with your AppleID

Unless you AppleID account has not been fully/correctly configured, or has been seriously neglected, recovery of the AppleID and password should not be difficult.

When you recover access to your credentials, you would be well advised to log-in to your AppleID account from a web browser - and verify/update any email addresses and trusted telephone numbers:

Otherwise, if you are able to prove original ownership to Apple’s satisfaction, you may be able to have the Activation Lock released. If you have the necessary documentation, Apple have recently introduced a portal though which you can request release of the Activation Lock:
