Hi.
I assume you are asking what happened to the escape sequence "\e" when you supply the command directly to watch.
I think the command is being scanned by the shell twice, once on the command line when you give it to watch, and again when watch executes it. If so, then the "\" will disappear, although I would have expected the "e" to remain.
You can test this -- suppose you use your shell script (the 2-liner with bash) as the command in watch. What happens then? ... cheers, drl

INOTIFY_RM_WATCH(2) Linux Programmer's Manual INOTIFY_RM_WATCH(2)
NAME
inotify_rm_watch - remove an existing watch from an inotify instance
SYNOPSIS
#include <sys/inotify.h>
int inotify_rm_watch(int fd, uint32_t wd);
DESCRIPTION
inotify_rm_watch() removes the watch associated with the watch descriptor wd from the inotify instance associated with the file descriptor

Removing a watch causes an IN_IGNORED event to be generated for this watch descriptor. (See inotify(7).)
RETURN VALUE
On success, inotify_rm_watch() returns zero, or -1 if an error occurred (in which case, errno is set appropriately).
ERRORS
EBADF fd is not a valid file descriptor.
EINVAL The watch descriptor wd is not valid; or fd is not an inotify file descriptor.
VERSIONS
Inotify was merged into the 2.6.13 Linux kernel.
