^C
Basically watchdiff command expect the command output is small enough to fit within a terminal screen size. If the output is longer than the screen height, only the final part is shown.
Use -C# option if the output is large and you want to see modified part only. In this case, you may want to use the -V option, since it is difficult to tell which part of the data is being displayed.
