Casio AE12 LCA (liquid-crystal-analog) watch Customarily, watches have shown some time in analog kind, having a numbered dial on that are mounted no less than a rotating hour hand and a longer, rotating moment hand. Several watches also Exclusive watches include a third hand that reveals the current second of the current minute. In quartz watches this next hand normally snaps to another marker each and every 2nd.
