Omega watches are mostly mechanical watches or quartz watches.

Quartz watch: It is an electronic watch, which is powered by battery.

Advantages: the battery-powered watch is accurate in walking time and uncomplicated in technology, which makes the price relatively affordable, and the compact "body" is very suitable for female compatriots;

Disadvantages: Everything will not be perfect, and there will be some defects. Quartz watches are limited to batteries. Generally speaking, a battery can keep a watch working normally for two or three years at most, and then the battery should be replaced. Under normal circumstances, the life of quartz watches is about ten years. When the time amplitude decreases, the time is no longer accurate.

Mechanical watch: it is powered by the rotation of the spring inside the movement, and it does not need the battery to provide power. Therefore, the working principles of mechanical watches and quartz watches are different, which can save the trouble of changing batteries.

Advantages: Of course, the biggest advantage of mechanical watches is that they don't need to change batteries. If the watch stops, just twist the crown to replenish power for the mechanical watch. The life of mechanical watches will be longer, which is also better than quartz watches.

Disadvantages: mechanical watches are made up of many mechanical parts, which are cumbersome and troublesome to wind at regular intervals.

They each have their own advantages. Quartz watches are accurate in time, fashionable and light in appearance, and need to be replaced in about two years. The life of the movement is not as long as that of a mechanical watch. The daily error of mechanical watches is relatively large, which will be thicker than quartz watches, but the service life will be longer without changing batteries, and the watch movement will be more ornamental than it should be. So many brands have the same style, both mechanical watches and quartz watches.
