    Vintage Casio Battery Advice.

    Hi Guy's,
    I have a vintage Casio F-8 that i purchased way back in 1979!
    It needs a new battery, do any of you know which battery
    fits this model???
    On the back of the watch it say's: JAPAN W 452917 & 58F-8
    Do you know what these numbers indicate?
    Cheers to those who can help.

    Open the watch and see what battery is inside. Be careful not to turn the watch while it is open (some quartz watches have loose parts inside).

    you'll need to measure the receptacle/housing and compare sizing to the following chart(s)

    Get the diameter right and then you may have to guesstimate the depth

    At least try to post a picture of the watch with case back removed, depending on the size of the battery holder, someone might be able to help you.

    I've seen a couple of vintage Casio watches with the 2020 battery.

    Ok, so i've measured the battery aperture and it looks as though
    the original battery was 23mm x 2 or 2.5mm.
    I know for sure it was a lithium battery and that it was 3v.
    Does this shed any more light on the subject.
    Thanks for the help so far guy's.

    So you could try either a CR-2325 or CR-2320, they are both 3V batteries.

    yeah the 2 first digits are diameter on lithium batteries, the 2nd two are depth

    So a CR23(diameter)20(depth - obviously stick a decimal point in the last pair) or 2325 should be fine

    The F-8 originally took a BR 2320 battery , the modern replacement is a CR 2320 .
