The watermark is encrypted so the information it includes is not completely known. However by comparing watermarks between books it has been shown that it includes identification of the specific book, the app or device to which it was delivered, and the Amazon user account involved.
Using KindleUnpack to convert to ePub, you can see the watermark in the comments in the OPF.
