And automatic winding is most practical for perpetual watch (I can't imagine winding perpetual calendar watch every morning.. thus while I love so much 3970 or 5970 manual winding were a bit head scratching). Having the same base calibar as 5074, 5078 is also automatic and that was head scratcher as well. So, manual winding 5339 and automatic 5074 both make lots of sense in terms of "practicality" in that regard.
Either way, as you say, any of these would be soooo nice if it were in the collection.... sigh....

On the other hand, a minute repeater might be the most difficult complication but I'm not interested in them. I'll always prefer a couple of chronographs
