Most of analogue quartz watches are of small sise, thin thickness, high precision and low price as compared with mechanical watches. So they are popularized worldwidly. But some mechanical watches have excellent qualities such as conventional quartz watches do not have, so they have a large market share in high grade class watches. We developed quartz watches which are superior to high grade mechanical watches by making up weak points of conventional quartz watches.
