Quartz
Nearly the downfall of the Swiss watch industry was and is the quartz movement. Loved by some and hated by others, the quartz movement uses a quartz crystal to create the vibrations needed to power a watch. More circuit than machine, quartz watches keep excellent time (better than COSC) for an often times a very cheap price and with little care needed. Shop for quartz watches
