watch
is available in Cygwin, in the procps-ng
⁰ package as listed here (this info can be found via the package search on the website, here). I don't think this package is installed by the default cygwin setup, but it is one I usually select on new installs in order to have the watch command available.
The location of tools in packages typically match package names in Linux distributions (the package containing watch
is procps on Debian and Ubuntu too) so if the Cygwin package search function fails you, info for/from Linux distributions may offer clues. In this example the exact naming is no longer the case, though searching for procps would find procps-ng.

[0] procps
is now deprecated (as noted here and here), the original package stopped being maintained and a couple of distros forked it to apply pending patches. In some places it is still called procps
but in others like cygwin the new name was used

Thank me later.
