  1. Nice watches, I wish I can still have mine, the Casio Data Bank DBC-62, and also I miss my Casio W-24A Marlin, my third Casio watch in the 80s after my Casio F-7 and the Casio F-10

  2. In 85 my uncle bought me matt black dbc telememo replete with angled face skinny dimensions and “key” key on the touchpad. Can’t remember the exact line number but what I wouldn’t give for that model!

  3. Any chance of purchase the DBX-100 from you? I got one from long ago but all the rubber panel got melted away… looking for replacement but not available.
    So good to see one that is in a good condition… Thanks for sharing.

What do you think? Please tell us!
