To wind or not to wind....I know this has been addressed before, but I haven't totally been satisfied with the responses I've read. I'm wondering if it is ok to occasionally hand wind an ETA 2824-2 movement. I've read in previous forum posts that it is generally not a good idea because it grinds down some of the internal gears that happen to be made of a softer metal (or something along those lines). However where I have really seen this do acutal documented damage is in watches that were not serviced for years while the owner contiued to manually wind the movement. I'm hypothesizing that the damage done by the manual winding occured because of improper maintinence (i.e. no maintinence).
Would it be fair to say that as long as the movement is properly lubricated and checked every few years manual winding isn't a big deal? I would think that ETA with it's quality standards wouldn't produce a movement prone to failure because of a built in feature. Obviously automatics are best wound when worn on the wrist or on a winder, but every time I set my watch when I'm traveling, or when it runs out a juice I notice that simply screwing down the crown winds the movement. I want to know that this isn't causing any undue harm to the watch.
Also, on a slightly different topic do miyota movements have the same reported problems?
