Hi friends....here my latest acquisition (i have it for free)...a very used Casio W-45 with 548 module 50m waterresistant
The strap isn't original and the case present a a lot of scratches but the module works fine with the basical function: light,loud alarm,chrono and coutdown.
I change the polarizer because the lcd was very fainty....
I don't know this model ( i'm not an expert about casio lcd watches) but i see in the web that this module was used in g shock model,isnt it?
Also I don't know the release year but a first glance i can suppose that came from 1983....but i'm not sure...i don't found this model in the digitallibrary.
Here some pics
