this is a common problem with howard miller clocks like yours. i have two and they do that sometimes. What I've noticed is that when it strikes the wrong hour, it's on specific hours (ie: it will strike 1 every time it's 3 o'clock. That's what my Urban II did). How you fix this is by moving the hands back or forward one hour and let it chime, then move the hands to the top of the current hour and let the clock chime again. repeat until the clock strikes the right hour, it may take a few attempts.

Didn't know they even made this is a quartz version -- might be part of the problem.
