To be sure, measure the actual width into which the strap will go. Quite amazing that such a watch is still working after many years. Good to know.;-)I was at my parent's over the weekend to clean out some junk from the garage and found my old casio watch I wore back in High School. The band was missing, but I just installed a new battery and it fired up. I haven't worn this watch in 30 years or so. Can I still get a casio band for this watch? Would a Zulu or Nato band look good with this Casio? I believe its an 18mm. Any suggestions?
