Zenith Special pilot radium questions

Hello. I have questions that perhaps some of you may be able to shine some light on. This is a late 1920/1930 Zenith Special Pilot's watch (movement signed GEORGES FAVRE-JACOT). I am aware that the upper bezel is tragically missing (although it was sold to me as 'complete'/'original'). This is a real pain as finding another one is almost impossible. Any ideas? Or is this a non starter? Could I make one?

My main question however is relating to the numerals. These Zenith's are sometimes found with white unlumed numerals. This one (above) has an orangeish application to the white numerals on its enamel dial (I had assumed this was worn out radium Lume) - however this example's lume has very little noticeable risen dimension to it. It appears as a very thin layer. Below is an example of the same sort of watch with a more commonly seen residue of radium lume on it. It is darker and less 'orange' in colour and more faded brown and also has a more visible rise to its application. What is going on here? Could the above be dead radium lume or has someone simply painted my numbers orange? Any ideas would be greatly appreciated. Thanks for reading.

Not an expert but at first glance I doubt this dial is original

There are many things wrong with yours. The " lume " might be the easiest wrong....need a back / inner glass cover pics, mvmt pics. With the number, side shot with the crown.

Looks like someone has badly 'relumed' the dial on the first watch (possibly with a paint rather than lume), does it have any glow under stone light? Hands relumed quite unpleasantly too, to my eye. You could have dial and hands more sensitively relumed by someone with those skills, to improve appearance, or just remove both and leave both bare. They aren't super super rare so you never know, with patience, you might find a bezel.

Are you selling it? If not someone has stolen your pictures and listed it on eBay.

I don't want to breach the rules of the forum.

A poor example of a relumed dial, and the hands have almost certainly also been relumed.

I don't have a stone light. (I actually don't know what a stone light is) - I had thought about scraping off the paint (if it is paint) myself. But am scared of cracking the enamel. Why would someone paint it? Bizarre.

I can't get a picture of the inner glass because I don't want to mess up the dial (I have no tools) - it seems someone has found a larger piece of glass than would fit the upper bezel that fits the lower bezel and just set it in place. At first I had thought this was perhaps something exclusive to earlier versions of this watch.

What makes me doubt that it is un original is that the previous owner embarked on a small repair at the 11. If it was bogus I'd think they'd just have somehow made a totally new dial.

[EDIT] Having looked more closely, I would say that dial may have been completely refinished. Also, the sub-second hand does not appear to be original, or correct.

I think that you are making a mistake by repeating the previous sellers claims on your listing.

The "repair" was probably used to add credence to his otherwise dubious claims.

Damn. That is a blow indeed. I will amend my listing. It was a 'reputable seller' - 5starwatches or 'Stromberg Time Gallery'.

I've just edited my previous reply, to leave some room for error. I am not an expert on the model, but remain skeptical.

as seen above ( last pic post 1): these are correct lume (colors) on a enamel dial-not Zenith (Benson)



Can you turn off the glass and compare with a loupe??

Here are some pictures with the glass removed - looks like original enamel to me?? due to the hairlines...
