The battery does NOT need replaced.
The word "Open" on this watch means that the sensor inside the back of the watch has detected that that the back is open. I ended up having to repair this problem myself after a local watch repair guy told me he didn't want to mess with it. You'll have to get a micro-philips screwdriver and remove a few screws and pop the end caps off to get to your problem.
After you have removed the screws and end caps inside the back there's a small spring that pushes against a copper disk glued to the back of the watch. The problem is that Casio has used a crappy glue to hold this disk in place and it needs to be removed and reglued to the back in it's proper place with super glue. It's a pain in the **** but I have repaired mine by doing this. BTW...I have found a video or another help for this fix on line so I won't go too much into it. Do a Google search and you'll find the step by step process listed elsewhere.

SOURCE: gasket repair
I've used a toothpik wooden or like the dentist uses and clear form-a-gasket silicone and put that in place of the gasket. and assemble the watch.wipe off any excessive silicone (be care not to have any or as little excess as possible)and allow to dry and then make sure your watch operates correctly.
