And obviously, if you don’t own (or plan to own) an automatic watch then you’d almost certainly be wasting your money.
But there are several good reasons to get one:
A big one is convenience. If you own an automatic watch that you wear often, but not permanently, a watch winder will allow you to have it ready to go at all times. This also reduces the amount of hand winding you’ll do on your watch which causes unnecessary strain on the automatic movement.
If you own multiple automatic watches, the above point is even more relevant because most of us don’t wear more than one watch at a time (yeah, don’t be that guy).
Another excellent reason to get a watch winder is if your piece has a complex perpetual calendar. A winder can bypass the need to go through any commonly elaborate resetting requirements if your watch has been stopped for some time.
