If I had to guess, I’d say it seems like something under the automatic winding bridge is making contact with the ratchet wheel.
Might be worth contact ALS to get their view on it, and have the problem corrected so that it doesn’t re-occur.
After a fair bit of image checking, you’re not alone. Looks like it’s a design flaw that they’re oblivious to or don’t care about.
Worst one seen so far…
Notice how the markings aren’t entirely homogenous, there appears to be a bit of wandering?
That would lead me to conclude that the automatic bridge isn’t as rigid as it should, and there’s some form of flexing which is allowing a part underneath to touch the surface. I suspect it’s the teeth of one of the wheels, which will be sitting in a jewel, hence where the slight lateral movement creates a contact point that isn’t in the same horizontal position each time it touches the wheel.
However, this image (too big to link normally) gives the impression that the bridge hasn’t been properly machined flat, but I think it’s just an optical resolution.

How it does look when new and fresh from the factory…
