It varies from watch to watch, but generally when you hand-wind an automatic you make certain parts spin much faster than they normally would. If everything's well-lubricated there it's less of a problem, but many watches are run until they start performing badly and by then the lubrication id failing.
The ETA 2824 and 2894 don`t use what I would term 'heavy duty' parts in the keyless work and it only takes a small amount of wear to create problems. The classic is the back of the winding wheel on the 2824, the ETA service sheet doesn't mention lubricating this point but I`ve seen plenty where there are witness marks to show it's been rubbing against the mainplate. There's a cause and effect debate her, is it wear in the mainplate where the stem runs that causes the winding wheel to rock slightly? Either way, it's a result of excessive hand-winding combined with lack of lubrication. I always grease this point, but I do that for any point where contact has obviously been made (witness marks).
Best advice I can give is to have the watch serviced after 7-8 years if it's used regularly, and limit the hand-winding to around 10-15 twists from rest to get it running well. If you're reasonably active this'll suffice. However, a 2824 takes 31 twists to fully wind whereas a 2892 takes around 55, so this is a rough guide!
It's ironic, the early 50s Omega bumpers aren`t particularly efficient hand-winders but the keyless work is very robust, on a par with the hand-winders of that period. There are no reversers although there's a ratchet wheel that can wear, but I if this is kept lubricated I reckon it'll last a long long time even though it spins rapidly when the watch is hand-wound. Stuff from the 50s from the top makers was built to last, that can`t be said for some of todays parts. ETA movements are fine if they're maintained and not ill-treated, but things go downhill if they aren`t.
That's my take on it, compared to the true pros I've limited experience and my professional training is limited, but I try to take a common sense pragmatic view.
