I recently plugged in my new winder, a Tech Swiss two-watch model. A member here told me a couple of months ago about the Orbita watch database. The Invicta listings were limited and none of the models specified the Miyota 8215 movement, so I looked up Miyota. There was one listing for the 82xx movement. It said that it should be wound clockwise 650-950 turns per day. So I set my winder for clockwise rotation, a 33-second burst every 15 minutes. The next day I look at my watch and it stopped. I increase the burst to once every 12 minutes and start it up again. The next day the watch had stopped. I hadn't tried everyhing yet so I don't want to exchange the winder. I flip it on counterclockwise, once every 12 minutes. A day and a half later the watch is still running in the winder.
If I get a watch with another movement I suppose I will have to go through the trial and error process again.
