SD43 movement issue

[brandrea]

Hi guys,

I tried searching for this as I vaguely recall having read about it here, but I’ll be darned if I can find it

So I noticed today that while winding my watch from stopped position, it felt VERY gritty. I’ve always noticed the winding on this 3235 movement is more “coarse” feeling and “stiffer” than the 3135, but I’ve overlooked it thinking maybe it will “loosen up” in time.

Background, I only wear the watch in rotation about 2 days a week, and it only sees office action

Any ideas on what would be the cause.
