I wanted a men's watch that would not cause me to have to get the left sleeves of my dress shirts altered (most men's watches are FAT!).  Because I travel extensively, I absolutely required a dual time function.  Further, because I speak and lead seminars, I needed a very easy to set stopwatch function.  Because my eyes are 'tired', I needed a watch with a white face that would be easy to read. And finally, I needed a watch with an audible alarm.

I searched for quite a while until I found this one.  It is PERFECT.  (Well, it is a bit cheap -- the hands look really cheap) But it satisfies every criterion I had and I bought four of them.  (Casio does change models frequently and my previous Casio which had all these functions was already discontinued.  So as insurance I bought a bunch of them.  Good idea! Since I often do strenuous things which can wreak havoc on any watch.  Yet I've only cracked one crystal (and it's way cheaper to replace the watch than the crystal!)
