Also with the handy on/off switch the chimes can be turned to "off" and silenced while the clock continues to keep time. This Howard Miller mantel clock has the battery powered movement and the set of clock gongs inside it. It also can be adjusted if the clock is running too fast or too slow; though I have not adjusted it.
This is the model number 512-688 which still has a version being produced today. Please contact me with any questions.
