That's the part that causes the dep cycle afaics.

By being hooked into multi-user.target, watchdog.service will have an
explicit
Before=multi-user.target
dependency.

multi-user.target on the other hand is an alias of runlevel2.target,
runlevel3.target and runlevel4.target and you explicitly requested
After=runlevel1.target runlevel2.target runlevel3.target
runlevel4.target runlevel5.target

Those are conflicting requirements, so systemd will drop the unit.
