This is a nifty, handsome watch from Casio.  Ever need a calculator, but never have one around?  Well, wristwatch calculators have been around for a long time.  This one has a lightweight resin case which looks like brushed aluminum.  It's a handsome watch.  Press a button, get the date.  Press another and choose between a calculator, alarm (with time signal) dual time and 24 hour stopwatch.  It can be set for 24hr. time so if you're a military  enlisted man and your C.O. asks you the time you can give it to him without doing mental mathematics.
No downsides to this nice looking watch.
