Quartz movement and movement movement different emphases, quartz movement is driven by electricity, the oscillation frequency of quartz crystal is very stable, so the error of quartz movement is very small, generally every error is less than 5 seconds, has emerged in recent years, clock radio fixed time every day to carry out automatic calibration of radio waves through the Henan Shangqiu launch, so long as the battery electricity, basically there is no error. The disadvantage is that the battery has no electricity to change to trouble.
The mechanical core is driven by mechanical energy collected in clockwork or during movement. This mechanical energy generally has a linear adjustment bias, for example, sometimes it's fast and sometimes slow. But with the development of technology, the adjustment of mechanical core is becoming more and more perfect.
In summary, personal advice is a quartz movement if it is short and practical. If it is a collection of ornaments, then the mechanical core is absolutely good.
