Casio Pro Trek WSD-F20 parts lot, case, NO BACK, NO GASKET, parts only

Does not work.  Repeat.  Watch does not work.  Parts lot only  Parts from a used WSD-F20 that stopped charging properly.  When plugged in it only gets to Casio screen and no further.  If you do some research its apparently a problem with this watch model and may be fixable with aftermarket battery packs.  However I tried that and it did not work.  I bought an aftermarket battery off Amazn and installed it end of January 2026 but it still does the same thing as it did before.  So I am done trying.  You get what is in the photos only.  As is.  Parts lot.  Comes only with what you see in photos.  No cable.  No strap.  No screws.  No gasket.  No caseback. Only comes with front of watchcase, module, old Casio battery, and aftermarket battery.   Used item so expect wear.    From smokefree home.
