I am trying to figure out how to shorten the wrist band on my Casio Edifice EFA-119.

Mcdevito75 here, If your Casio has a metal band, you can remove 1--2 links, this takes a special tool called a link remover, best bet is to look for a small watch repair shop in your area. If your Casio has a strap, the buckle may be able to move up the strap to fit your wrist, if so, move the buckle up the strap to fit your wrist and cut offf the exccess strap. If not, you"ll have to replace the entire strap. Hope this helps.
