I'm another AT41 (8900 movement) owner who has had the same experience. I've owned many mechanical watches, old and new, manual and automatic, and have never had another that was nearly as hard to wind as this one. To the point where I worry sometimes that I'm going to break something. The crown turns and the watch winds, but it requires some torque. I did not experience anything like this with the 2500-era AT I owned previously, or the SM300p ceramic I recently owned.
And as others have mentioned, this is a known thing about this watch. The watch works perfectly and keeps great time, and I have no concerns about any other aspect of it. I just deal with it, and figure it'll (maybe) get sorted when it's time for a service, though I may opt to do that service while it's still under warranty...
