Do n’t see that some mechanical watches are only basic functions of time display, but in fact it is much harder to imagine the parts of the movement and maintain the stability of the overall structure than expected.So some people will say that a mechanical watch is an implicit watch complication, which means that in terms of production difficulty the craft value of a skeleton watch is just like a complex function watch. It is worth savoring a mechanical watch. Work hard on the design. The internal structure of a mechanical watch is relatively complicated. It depends on the drive of the mainspring to maintain the operation of the watch.
