I have a DW-7500 pictured here:
The watch is an old purchase off ebay and Im just now starting to investigate it. I have determined that it is missing the white plastic "module insulator" internally. Here is a picture of it next to a W-80US with the W-80US insulator installed.
The backs of these modules are identical. The "module insulator" (casio term) fits both watches perfectly, however this insulator does not serve to fill in the gaps between the module and the pushbuttons as pictured here in an unrelated watch:
Ive called casio (US) and they dont even seem to know that this watch (DW-7500 module 913) even exists. Does anyone know how to track down an insulator for this or a similar watch? Obviously there were not that many different styles made when the DW7500 was released.
Any help would be greatly appreciated.
