I have a ladies timex indiglo watch that I was able to get the back off and replace the battery but now I can NOT get the back on again. It doesnt seem to have any grooves on it. It seems as if it would just snap back on but I can't seem to either push hard enough OR that is not the way to get it back on. Please help, I want to wear this watch.

I have an old Timberland Indiglo watch in which I had the same problem. I folded up a paper towel for padding and I used two sets of pliers, one to hold one side of the watch while I used the other set of pliers to snap the back cover closed. It took two seconds to do.

Ok I had an Indiglo watch . Changed the battery and no matter how hard I tried ,I could not apply pressure sufficient enough to get the back to click.Nothing worked! Finally, I had another watch that I was in the process of changing the battery in as well. I noticed the back of this watch was almost the exact same size as the Indiglo, so I put the other watch back against the Indiglo's back while it was in place , I stepped on it over the carpeting. With very little effort, I heard it immediately snap into place. I'm thinking any hard ring that can apply pressure evenly around the outer circle will do the same thing, but another watch back was the perfect size for the job.
