How can I get colored output of `systemd` commands run with `watch` inside xterm?

Somehow I'm unable to get this working with color output, it works but no colors are shown. --- 1. I'm currently using these alias'es in my bash shell:

alias Xterm='xterm -geometry 132x60 +dc +cm -e '
   alias Watch='watch --color --differences --interval=1 --exec '
   alias xterm-watch='Xterm Watch '
   alias _nc='networkctl'
   alias nc-status='_nc --no-pager --stats --full status'
   alias nc-status-watch='xterm-watch nc-status'

1. $TERM is set to xterm-256color 1. When i enter nc-status-watch at the bash prompt, an xterm window pops-up correctly with a watch command running the networkctl command with it's arguments. But the output does not show any colors. nc-status-watch" class="img-fluid rounded" style="max-width: 100%; height: auto; margin: 10px 0;" loading="lazy"> How can I get colored output of systemd commands run with watch inside xterm?
