An unexplained phenomenon! Watch gains 4 minutes a day but only when on the watch winder

Archer

A watch that runs fine other than on the winder...if you feel that warrants a return, then that’s up to you.

If the sales agreement allows you to return the watch within a certain period of time than you have to decide what to do. But I don't think they would accept a return because of a 'it doesn't wind well on a winder but works fine on the wrist' claim. If the watch works as intended on your wrist than there is nothing wrong with it.

"Double the amount of TPD by selecting bi-directional" That's what it says on their website:

Excess amplitude is most likely to happen at full wind, so when the winder is winding it all the time, this is when it will happen...

What should I do when the watch is rebanking?

It seems to me that my Spectre is being in the same situation, after I forgot turning off the winder and let it run for 1.5 days.

I would get a winder that you can adjust to the proper turns per day...
