Cosmotron from 1971 – What’s So Unusual?

Citizen made many different Cosmotron models, an interesting hybrid movement that became obsolete well within 10 years of its launch in 1966.  Here’s one, case number 4-480279, from November 1971:

A passing glance might suggest it’s a straightforward enough rather plain model with the 4840 date only movement inside. However, you may already have spotted an unusual feature – zoom in and it becomes clearer:

Yes, it’s a printed crystal, with applied hour markers and the Cosmotron symbol plus the dial code on the dial itself. The rest is printed on the underside of the glass. As far as I know this is the only such model in the Cosmotron line-up, but if you have seen another please let me know 🙂

    Interesting! It looked like the applied markers were off thew mark — but there are no applied markers at all. Citizen certainly has done some novel things over the years.

      Hi Marvin – sorry my text was misleading; I’ve now edited it! The hour markers are applied to the dial. Actually, I reckon the crystal has been replaced at some point and isn’t quite inserted in line, and the camera angle also exaggerates that, so your are right there is an alignment issue. It’s the crystal though, not the markers. I will have to pluck up more nerve to try and adjust the crystal though!! Don’t think I’ll find another one too easily….

    Hello Stephen

    Letting you know a Chronomaster Diver is being advertised as the “holy grail” on Ebay at the moment; you might already have found it, and they do want miraculous money for it.

      Hi Steve – I hadn’t seen this, so thanks for the link. I’m actually not surprised about the price, this one is very rare and goes for a lot of money. Having said that it will be interesting to see if it sells at that price, given the condition issues. I’m happy I’m not a huge fan of divers!! Stephen
