I'm realizing this morning that when I was fiddling with my watch last night, I might have operated the quick set function while it was in the danger zone. It had lost power reserve and stopped moving halfway between changing the date, which had never happened before, so I started it up again and did a few quick and hand set changes of the date wheel to make sure everything was okay as like I said I didn't know if a watch stopping mid date change was bad for the movement. Anyway, I might have made those adjustments while the hands were in the danger zone, but I'm not sure. Would there be clear signs of damage had I done so? This morning the watch works fine and the date wheel changes normally indicating there are no broken teeth on the wheel or anything like that, but I don't know. Let me know if I should still be concerned, or if it's probably fine.
The watch is an Invicta Pro Diver with what I think is a Seiko nh35 under the hood

So the wheel we're talking about is the black one at around 11:00. It's made of plastic on this caliber, so not the most robust thing in the world, but it does have a safety engineered in. See how the arc on that wheel from around 9:00 to 1:00 is attached at 9:00 but not attached at 1:00? That means the finger that pushes the date wheel forward can bend out the way if the user actuates the quickset at the wrong time.
In short, I think you're fine.
