    Casio dw5600c crystal Japan s vs. Japan o

    Hi.

    I know there is many different models of a dw5600c, and different letters stamped on the screwback.
    But what is the letters on the crystal meaning ?
    What is the different between Japan S and Japan O ?

    If the display letting follows the caseback stamping then probably associated with the factory it was manufactured in, or possibly when it was manufactured. For example the DW-5600C is stamped with an "H" for Hiroshima, so maybe the O and S are similar to that? Just a guess :)

    My 5600c has the 691 module and a serial number. "Japan A" on the back and "Japan S" on the front if that's any help?

    I'm sad to report I had to ask my 5 year old son to read the Japan S on the front; I never thought the day would come.
