Yeah- looks like oil. Not that I personally would ever attempt it- but would anyone who does watch restoration/ repair professionally weigh in on using something like Naptha or Denatured alcohol on a dial like this to remove the oil without effecting the painted surface? I have worked with fine art conservators that use either as SOP (depending on application) for cleaning oils, tobacco staining, water damage- etc off priceless works of art.

Only clean a dial with solvents if you are prepared to destroy it...
Everyone seems to be assuming that the dark patches are stained with oil - to me it looks like those patches are what the dial should look like, and the parts that are less black have something on those areas...almost powder like in appearance. If this watch came to me, I would first use the standard cleaning sticks from Bergeon to lift off any loose dirt, but otherwise would leave this alone.

Looks like oil stain from a bit too much lube during a service. I wouldn't give it a second thought. It may just dry up and become invisible over time. Depending on the type of oil.
I wouldn't disturb the dial trying to clean it.

So the powdery coating is most likely the degeneration of the surface treatment...yikes!
