Yes, but as every other sundial, your Ring Dial is subject to the difference betweem our modern, artificially designed concept of time and the time indicated by the movement of the sun. This difference is called the Equation of Time and varies between -15 minutes and +15 minutes and causes the "inaccuracy" of your dial. Your dial is working perfectly well. The only way to compensate for the Equation of Time is to adjust the dial every day for it. Ekkehart von Wartstein
