Because a proper, well designed winder (set correctly for your movements) mimics normal wrist movement, it should not put any more wear on a properly maintained watch than the watch would receive from daily use. However, if the movement has not been maintained (properly overhauled at least once every 5 or so years), then I would recommend against using a winder. For whatever it is worth, the only watches that really ought to be kept on winders are those with non-quick set dates that take so long to set that, were it not for the winder keeping them charged, they may not get worn because they are a pain to set.
As far as 7750s go, the few times I have placed my secs @ 6 Daytonas on winders (my winders are all bidirectional), even set for 1000TPD, the winders have failed to keep the mainsprings fully charged. Everything else does very well on winders at their recommended TPD settings
