The white on black contrast and fat hands caught my eye.  I don't need my reading glasses to tell the time on this watch in any light.  Casio has an excellent reputation in my experience.  The price of well under $20 is a sure seller.  Being self-employed, its rare that I need a watch, haven't worn one since 2001, but it is nice as I'm doing shopping around town near closing times.  I could always pull out my cellphone to see the time, but there is nothing as simple as a quick glance at this watch.  I go swimming everyday, this watch is water resistant enough to handle that easily.  Its a simple watch, it doesn't fetch the paper or tell the time on Mars, its just an excellent watch.
At about 3 yrs, this watch stopped running.  I took off the back to see that the battery is a Sony 377SR626SW.  I ordered a strip of 5 ea. of these batteries here on Amazon.  I put one in, tested the watch in a bowl of water overnight to see if it still ran, no sign of moisture in the watch.  I'm swimming with it again for 3 weeks now.
