I have a dial that has a similar effect around the sub-dials and the outer step as well. Not as dramatic and bright white as the OP watch but quite apparent. For some reason, this particular damage is quite appealing to me. The base dial color is also a bit faded. Not brown, though. You can also see a tiny bit of loss to the printing around the edge in a few spots.

Have you examined under magnification (avatar!) to ascertain what the ring might be?

It really just looks like fading or wear as far as I can tell.

I always find these discussions of how watches age fascinating. Why does one speedy dial go brown and another go Grey? Who were the different contractors, what paint formulas were different- this is what I love about this place.

But the fact that this thread has made it this far with a title like “sugar rings” and there hasn’t been one reference to this guy blows my mind!

This has been discussed before. The person he is referring to had recently bathed, and thus there was a whitish residue on the outer surfaces.

The other detestable comment shows that in his obviously drunken stupor, he confused Aveeno cream residue with Kosher salt…
