I ordered some of the small clocks that go into a 2 3/4" hole. I didn't think to ask what the overall diameter of the clock is and now I find they are close back east. Does anybody have one to measure? I can't imagine them being more that 3"-3 1/4" but just want to be sure.... The part # is E-72-MM-R I did look on the website but just not finding the information.
