My Casio G Shock is circa 1985 or so. I know this because I got it at the begining or either my freshman or sophmore year of high school. On the back it says in a circular pattern: CASIO  DW5600 JAPAN H ST.STEEL 200M WATER RESISTANT. In the middle of the circle is the phrase SHOCK RESISTANT.
This watch has been EVERYWHERE. I had this watch in the arctic and the antarctic. It's seen more mileage than most people in two life times. I friggin love it. My old friend is however going to be in need of a new band soon. Can I get a factory replacement? I would also like to know if there is an owners manual for it anywhere? IS this the first model of G shock? Also can the light inside be replaced? It's not as bright as it used to be but who is?
Thanks for any help.
