I think that the P90xx movements do wind in both directions and need the higher TBD settings.

Any fewer winds per day than necessary just to stay at a steady state of wind and any movement will eventually stop right on the winder. Typically, if the watch stops on a winder, you move to the next higher number of TBD and so on until it no longer stops while on it.

On a winder, the rotor doesn't turn, the watch turns and the weighted rotor just stays in one place, so the watch is actually turning around the rotor rather than the rotor turning around the movement.

Here is some individual movement info.

Thank you for the info (especially the rotor explanation)

It’s an odd one. I’ve had it on 900 TPD all the way up to the max of 1400. I might try ‘permanently on’ just to see how it performs for a week. If that works I think I’d just stick with winding/wearing though.
