When I don´t use them, they sit in a box. I don´t wind any (except some 5 or 6 turns sometimes on A2824s or more on 21j, never A7750s) and skipped the winder. If I want to, I have 3 to 4 running all the time, just by picking them up sometimes in the morning/evening and changing watches when I arrive/ leave home, just as I change clothes.
With A7750s I´d be just a bit more careful, otherwise I see no special benefit or harm, I just think the less unserviced reps run, the longer they hold (includes running at least once every 2-3 months) as anything mechanical with gears.
