I own the PO GMT....the watch is worn every day/all day. This may sound dumb but is there a need or requirement for me to ever "wind" it?.....

You would have to have a very sedentary lifestyle to ever have to wind it, are you a monk trying to reach enlightenment?

It's really not possible for us to say. Watches generally keep the best time when they are closer to fully wound than towards the end of their power reserve. Depending on your lifestyle and how you wear the watch, and how recently the watch was serviced, it could be anywhere in this range. Most likely you are fine, but if you're curious, you can leave the watch unworn one day, and see how long it runs before stopping. That will give you some data.

You wear it everyday… has it ever stopped unexpectedly?

If not, there’s really no need to manually wind it. I say “really” because I’ve noticed many autos to be more accurate (by a marginal degree) when fully hand wound.

if you aren’t seeing timing issues or having it stop, then no. With that said, if you ever unscrew the crown to change the date or set the time, I’d go ahead and give it a few dozen winds. It won’t hurt it, and will top it off it is a little low.

Unless you’re one of those 1,000 pound people who really can’t make any movements other than eating more cheetos, I don’t think you can be sedentary enough to wear an auto all day without winding it further. I’m active enough in my sleep to continue winding an auto

The 8900 series are said to keep accuracy even when there's little spring power left. So I guess you need not ever wind, even when worn just a little during its 60 hour reserve time.
