I bought this to replace a W736H, the newer version.  The 736 is much more attractive in my humble opinion, but has a plastic dial.  Mine was destroyed by a few drops of insect repellent.  This version was claimed to be mineral glass, but is not.  Casio says "resin" dial.  Plastic....

Fine timepiece for the price (less than $18 in my case for this one).  Vibration alarm is great.  The backlight is pretty.  Easily set, etc.  But, Casio always had mineral glass crystals....even in their cheapies....What next?  Self driving electric cars?  With plastic windows?  Oh my.

Just for the record:  Casio, if you are listening, put the 736 in a better case with mineral glass,  price it accordingly and I will buy one.  Hell, I'll buy two!  It would be the perfect outdoor casual timepiece.
