A watch file specifies where to look for new upstream releases of a source, 
uscan [1]  is a tool that parses the watch file and downloads the latest 
tarball if there is a newer release. A watch file does NOT fetch the 
dependencies of a source itself (assuming that is what you meant in your 
original mail). Watch files are also used by UEHS [2] to show packages that can 
be updated in Ubuntu. The equivalent site for Debian would be DEHS [3]

Note that you also should read up on uupdate [4] and this [5]
