I asked him: "When I jump up, after having rested without movement for a long while, and at the same time turn to the other side, I feel a sudden, sharp pain here and here." His reply was simple: "Then don't do this!"
Well, of course this little anecdote does not mean I don't take your worries serious. Yet you have to imagine yourself that the movement of the hour hand by the GMT pushers and by the crown involves two different sets of wheels, that normally operate separated from each other. Pulling out the crown into the "time setting" position engages one of the mechanisms, which of course interferes with the other one, should the latter be employed as well.
More or less the same happens in your first example: the date display mechanism engaged by the movement's hour wheel is a different from the mechanism of the date quick-setting. Mixing these two can result in damage of either of them, unless you introduce a mechanism that comletely decouples the date wheels from the base movement, while the quick-setting function is used. Moser did this, but they are the only company I am aware of.
