To me it looks quit nice, I am not sure if the crown is original, haven't got any photo of the movement.
The case looks a bit beaten up, pitty i dont have any photo of the back.
the patina looks a bit different from what i read that it is common with spiderweb like patina.
It's too far gone for me, both dial and case, I'd pass.
Here's one I sourced for my brother-in-law a couple of years ago which also has speckles on the dial, but here the glossiness of the dial is intact and there are much less speckles, this one I find much more attractive. Hold out for a better example.
