Ok, so you actually have a driver bound to that device number, and it
should not trigger the usual module autoloading mechanism.

What does:
ls -l /sys/class/misc/watchdog/
and
ls -l /sys/class/misc/watchdog/device/
print?

Does the /sys/class/misc/watchdog/ directory exist, before you load
the module you expect to be the driver behind /dev/watchdog?

To clarify, the other modules get loaded, after you loaded but module,
the above /sys/class/misc/watchdog/ directory exists, and only if you
read from the device, all the other modules get loaded?
