Sweep seconds is a type of second-hand found on watches and clocks. It is characterized by a smooth, continuous motion around the dial rather than the tick-tock motion of standard second-hands. The sweep of the second-hand is a more accurate measurement of time, as it offers a precise indication of the passing of each second. The sweep hand is also a popular choice for aesthetic reasons, as its smooth motion provides a sense of dynamism to the design of the watch.
