Does the glass on your clock have a crack or chip in it? Do you want it to look brand-new? At Norkro, we can help with that. We offer our customers a wide range of glass replacement pieces for all different clock brands. The glass diameter is measured flat across the back of the glass, edge to edge. It is not measured over the dome, so you can find the proper size for your timepiece. We will ship the glass safe and secure so that it arrives exactly how it should. It is easy to replace and put in your clock— and if it doesn’t fit, you can send it back and find the right clock glass replacement for your timepiece.
