Winding question for P9000 movement

[rr-nyc]

I've never let my 328 run down nor have I ever wound it. (When I'm not wearing it, its on a winder)

I finally let it run down over the course of the last couple days which I don't believe was near 3 days and concerned me. But even more alarming to me was as I wound the watch, it felt very rough to wind---Is this normal?

It doesn't feel like anything is grinding but the resistance would vary on and off per winding cycle. I don't want to mess up the movement so please give me your feedback
