What is analog movement as apposed to quartz movement?

Answer 1

Analog movements can be either quartz or mechanical, but all digital watches have quartz movements.

With respect to watches, an analog movement can be quartz or mainspring. Analog refers principally to how the time is displayed - by the use of hands. All digital watches have quartz movements, meaning the time is kept by the counting of pulses generated by a quartz crystal at a precise frequency, and displaying the time as digits. Analog watches are mostly digital these days also, using a quartz crystal to generate pulses, counting those pulses digitally with bit counters, then electrically triggering the mechanical movement each second (or equal portion thereof).

Mainspring watches are all analog. They use a mechanical clock movement driven by a mainspring to move the hands. Accuracy is determined by the period of a hairspring flywheel spinning back and forth, allowing the movement to progress a fraction of a second with each half cycle. Automatic movements use an unbalanced flywheel to wind the mainspring automatically as the watch is worn and moved on the wearer's arm.

Answer 2

An analog movement in a watch refers to the use of physical moving parts, typically hands, to display time. Quartz movement, on the other hand, relies on an electronic oscillator regulated by a quartz crystal to keep time accurately. Analog movements are traditionally associated with mechanical watches, while quartz movements are more accurate and require less maintenance.
