When I had my green teak dial AT the winding was really unpleasant—I know exactly what you mean. And I too tried to find a winder. It was tricky because the crown is fairly large. Most winder seem to be designed to help folks wind watches with tiny crowns (and they do help with that): the purpose seems to be enlarging the grip, not leverage per se.
Every one I tried was either to small to fit over the crown or otherwise threatened to scratch the hell out of the crown or the case.
Maybe you’ll have better luck. But in the end I just decided to tough it out. Latex gloves can help—no joke—or even holding the crown and turning the watch.
