This is just my opinion. If your winder does not include a periodic rest cycle, then the reserve of a watch in that winder will increase or decrease over time, until it either becomes perpetually overwound or it stops. Therefore, I would put the winder on a timer, so that the mainspring can unwind to some degree during the rest cycle, and with the winding speed set sufficiently high for the watch to not stop during the rest cycle. The six-port winder that I just purchased includes a daily 12-hour rest cycle. I have yet to have a chance to experiment with it. I went cheap, BTW, and the motors are not as quiet as I would like.
