I purchased this watch from another website, and she was really happy with it.  However, after only a year the battery is dead.  Seems to be a chronic issue with these watches.  In replacing the battery, I turned the battery cover too far resulting in damage to the soft aluminum case of the watch.  I was able to replace the cover, but I am positive that the watch is no longer waterproof.  We will have to keep an eye on it.
Speaking of the aluminum case, The watch looks like it has survived a war from all the dings and scratches in it.
If this watch survives another year, there will be no battery replacement; it will go to the trash bin.
P.S. to replace the battery, simply turn the battery cover on the back of the watch ONE QUARTER TURN ONLY.  The cover did not pop open for me, so I kept turning, thinking it needed to go further, or that it might unscrew off the case.  Well, it kept turning, and kept turning, and kept turning.  After prying the cover off, I realized that I had forced the blades of the stainless steel cover through the grooves in the aluminum case.  Trust me, it did not take that much effort to force it.  Lovely.  Somehow the cover seems to close somewhat snugly, but it is not a tight fit.  It is a horrible design if you ask me.  They could have printed an "open" and "close" on the cover/case if they wanted to.
