Analog Display

Traditionally, watches have displayed the time in analog form, with a numbered dial upon which are mounted at least a rotating hour hand and a longer, rotating minute hand. Many watches also integrate a third hand that shows the recent second of the recent minute. Watches powered by quartz have second hands that snap every second to the next marker. Watches powered by a mechanical movement have a "sweeping second hand", the name deriving from its continuous smooth movement across the markers. All of the hands are normally mechanical, physically revolving on the dial, although a few watches have been produced with “hands” that are replicated by a liquid-crystal display.
