Who needs a second hand anyway?

As someone of a certain age, as a young child I was taught how to read the time using an analogue dial on a clock or watch. I suspect things are a little different now, with kids more used to digital displays on computers and smartphones. But I have some not-so-fond memories of trying to grasp the concept of the minute and second hands on an analogue display. How different my childhood could have been had someone, somewhere designed a watch with one hand rather than two.
