    Two questions:
    - where can I got an original (branded) Omega crystal for my watch? It's a 1970s SeaMaster.
    - how do I measure it or know what kind of crystal to get? From the outside it's one size and from the inside it's another:
    inner diameter = 27.79 mm
    outer diameter = 29.61 mm

    Omega crystals are specific to the case reference.

    It's a 751 37mm caliber. Would I need the exact code from the back?

    Once you get the reference number you can try Ofrei.com. They have a page for Omega or you can call them about the crystal. They are in the USA but I don’t know if they ship internationally.

    Here's what I see at Boley.de:

    Crystal:
    Omega PZ5118LL Plexiglas (weiß) 9651PZ5118LL
    Omega PX5118LL Plexiglas (gelb) 9651PX5118LL
    Omega PZ5118 Plexiglas (weiß) 9651PZ5118

    "Gelb" = gold ring.

    I think that the "LL" is the day/date one but you would need to check with a parts supplier on that.

    Thanks. With all the Crystals on ebay, didn't find one for PX5118. Any other ideas?

    Is it in good condition? Branded in the center? I'd also prefer to have one with the date (day/date) magnifier if you have. How much?

    Cheers, M
