All Astronomical clocks have moon dials as well as dials for the movements
of the other main planets. The earliest ones were probably made in China
over a thousand years ago and the earliest I know of around here was made in
about 1350. You will also find moon dials on many English Long-case clocks
(grandfather clocks) as they were useful in planning journeys and in knowing
whether it would be safe to travel at night and if you would be able to see
your way. Their popularity waned a bit when street lighting became common
but many of the cheap (and not-so-cheap) 'fashion' watches today have
similar dials as an added decoration - but very few get set to indicate the
moonphase correctly!
