Can't answer that. I've got quartz clocks around the house that are deadly silent and others that click every second off. Maybe ask one of the guys that do the conversions. Toll free number here. http://www.autoinstruments.com/
Drive up "ole red" into the parking lot of the facilities that rebuilt your clock. Don't stop performing smokey burn-outs until someone assists you that should get some quick answers.
I, like John, have had both non-auto quartz clocks that are both silent and audible. If you just noticed it now, there may be a problem starting. A quick call to their number may give you a better idea.
