The inside was clean with Windex, as it was simple dirt. Then I followed with Goop.
I cleaned the whole case and the lens.
The label would refuse to come off, though the top one, that was stuck to backelite, did come off after Goop application. Mineral spirits did not help either.
Eventually I applied IPA, and after initial massage it came off pretty fast.
Alcohol left some white residue, but that rubbed of with dry paper napkin, and then with some Goop too.

The result is not bad: it is not crystal clear, but not as yellow as it was. Given the yellow color of the dial, it is quite passable.

The top. What you see is not dirt but the structure (the top is very clean)
interacting with light. I still am mulling whether to apply some brown shoe polish. I just might.

Front. I have some Goop smeared on cloth, hence the spots; but I noticed those will dry up eventually.
   

Lens
   


What you see in the lens is the items behind and not reflection, so as I said, it is fairly transparent.
