With thanks to Paul (aka ‘1386paul’) who is something of an expert on Citizen’s vintage divers, I have made two amendments to the Diver Page. First was to remove an image of a Crystal Date model which had a wrong, and much later, bezel fitted.
Second, I’ve removed the reference to (and pic of) a 52-0110 model with no lume to the right of the date window. Paul has advised that he’s never seen another example so it does not appear to be correct.
I really appreciate Paul taking the time to let me know – I want my reference material to be as accurate as possible 🙂

I agree with Paul that the 52-0110 without lume had to be removed. Black dialed 52-0110 has two dials variants . Other version has individually placed lume dots, which I believe can be detached. I believe in this case one of the dots had just fell.
Best,

Hi Mikko, thanks for your observations, they are very helpful. I’m checking it all out with Paul.

Hi Stephen, I own both black dial variants of the 52-0110. If you need photos or any other information, I’m happy to provide them. At first clans they look quite similar, but there is fundamental difference how the dials were constructed.
Best,
Mikko
Hi Mikko, photos will be great, thank you 🙂 – I’ll email you
