1. When the mechanical watch travels differently from the quartz watch, the second hand of the mechanical watch is continuous and continuous.
2. Due to the complexity of the movement of the mechanical watch, the travel time error is relatively large (depending on the brands) and the normal allowable range is +-45 seconds. The error of the Observatory's movement is small. The one-day error is within -4/+6 seconds. The error of the mechanical watch cannot be accumulated. The watch must be debugged for a period of time.
3, fine craftsmanship, easy to use, on the foot spring can take more than 36 hours.
4, long service life.
5. The appearance is heavier than the quartz watch (depending on the brand), some brands are also very thin, but they are generally manual mechanical watches.
