Usually you would need a watchmakers press for closing the watch back. Without proper tools it is quite difficult, but you can try the following.
Take a leather belt and lay it flush on an even, solid surface (stable table will do).
Undo the strap (both ends) from watch case by pushing spring bars inwards with pen knife.
Lay the watch crystal face down on the leather belt. Belt must be wider than watch itself and the leather must be quite hard and even, not soft.
Find the small groove on watch case back and align it very carefully to the watch's winding stem, so, the stem goes directly in the middle in protrusion. Slightly push the case back into the watch case at that groove point and gradually apply pressure with fingers going all way around the case back. Use your body weight if needed. You should hear "click" sound when the case back jumps in to place.
If this does not work, there is no other way, but to go and see watchmaker.
Hope it will work for you.
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.
Just enter the number from the back of your watch into the search box, and download the instruction manual. Get manuals for Kenneth Cole, Timberland, Ted ...
Ive heard people say many times to put cell phones in a bowl of dry white rice to remove moisture from them,so Im sure it would work for a watch as well. Just make sure to leave the watch in the rice over night,and make sure to have none of the watch showing in the rice---it will need to pull moisture from within the tiny parts.
