For that you need tool called watch caseback opener. It looks like knife, only the blade is very short, curved and hardened Plenty on ebay for around 5 GBP.
Ordinary knifes wont work as they aren't hard enough and you can damage the watch and injure yourself.
If you gonna try to use chisel and hammer action, then you will damage your watch definetely.
Why don't use watchmaker services? Battery replacements are not very costly.
there is aspecial tool to replace watch backs if it wont click back on with fingers dont press too hard you might break the glass. walk into a shop that fits batteries and say you got it done and it fell off. maybe a small family jeweller would be best. if this helps please rate

They all set pretty much the same. Here is the general walk through from the Cole site:
Press the lower left button on the Kenneth Cole digital watches to cycle through the various modes. Press it three times to get into time mode (the face should be blinking). Press the upper right-hand button to change the seconds. Press the lower right-hand button to select the minutes.
Tip & How-To about Watches
Changing Watch Batteries
Lots of posters ask "what is the battery in my (name of watch)" with a view to changing it yourself. This is a bad idea for many reasons. You don't have the tools or knowledge to remove a rotary screw on back, or the gasket sealant for a waterproof watch. Some fashion watches have 4 traditional screw and need professional grade jeweler screwdrivers. Also, there are about 20 batteries commonly used in watches, in various sizes and internal technology, Lithium Ion, Silver Oxide and Manganese Alkaline. If you buy them, you generally have to buy 10!
Don't sweat the details. Just take the watch to your local jeweler. They have all the batteries at hand and the tools to remove the back. It is done whilst you wait for $8 to $15!

Are the hands moving but out of step with the digital display?
If so then try pressing the "mode" button to reach a mode that allows you to set the hands (on my Casio it is "HS"), I would expect something similar on yours.
You can then alter the hands by pressing one of the other buttons. I would expect one button to advance the hands and another to ****** them.
