A watch dial which has separate displays for the hours, minutes, and seconds. To achieve this the hands are mounted non-coaxially, meaning they do not share the same pinion (a traditional three-hand watch has all three hands mounted on the center wheel pinion). Despite not sharing the same pinion a standard movement can typically drive a regulator dial with some slight modifications. Historically, watchmakers would use regulator watches as highly accurate reference timepieces to help time and adjust their watches. This even carried over a step further to marine chronometers. (“Regulator” not to be confused with “retrograde”)
