    No sapphire, really?

    I think the GMW-B5000V-1ER vintage looks really nice and I can understand the price hike with only 300 available in the UK.

    Any watch however at a £900 price point should have Sapphire glass as part of the specification. Come on Casio, £900 and mineral glass. Really?

    I see where you’re coming from, given that many watches at the $200 price point have sapphire crystals. But I think it may be more than just a cost cutting measure. Sapphire crystal has different optical characteristics and could interfere with viewing angles. Anti-reflective coatings can help with this, but I still find mineral crystals to look “better” than sapphire, subjectively.

    Agreed. The cost difference of sapphire vs mineral in absolute terms is quite small. Casio strangling the profit out of you.

    Would it be more brittle? Especially when polished flat and thin?
    AR coating and other things ... which for limited 300 watch run are too much of the investment.
    Some things are not just swap especially in product with such high performance characteristics.

    considering theres been only like 2-3 (if that??) all digital Gs ever with sapphire, i dont see why they would make a special effort for that model.

    There is a 60$ watch from Casio with sapphire, the BEM-111.
    So Casio is aware of this material and is using it in dress watches.

    When it comes to diver type tough watches Casio (and Seiko) seem to prefer the more flexible standard glass.
    Sapphire is a bit brittle.
    You see no pictures in my post?
    Photobucket decided to lock my pics behind a 40$/month prescription service.
    I used their services since 2009 so the most of my old threads have Photobucket pics inside.
    If you stumble across one of those threads and want to see the pic, PM me and i will re-attach it.
    What can we learn from all the lost information?

    Sapphire glass does not interfere viewing angle. There is the same STN LCD display as GMW's have on a real diving watch - Frogman, and it has a sapphire glass. All works well on an angles.
    For the price of ANY of the GMW, Casio should be using a sapphire glass as a standard. Another likely option though is that the lack of sapphire can be also deliberate. Maybe is some future Casio is planning to release a "limited" (in constant sale ) GMWs with a sapphire for eg £1500?

    That's the point and I agree with you, they should not be making a special effort. At this price point it should be standard.
