This watch is an affordable serving of awesomesauce!  I admit it, I'm a cheapskate when it comes to watches. I want my daily wear watch to be cheap, tell the time, glow bright blue when I press a button, tell the time, not cost a lot of money, and be easy to set the time. Oh...and tell the time.  This watch excels at all of those requirements, and does it FLAWLESSLY.  This is the third one of these I've owned.  When the battery dies, I just buy a new one.  I once tried to replace a battery in a Casio watch but I was not able to close it tightly enough to maintain the waterproof seal and a few showers later, it was kaput.  The Casio service centers charge $30 for repair, so why bother when you can get a new one for under $20?  Previous to this current one, I owned 2 93H-1AVs.  There was one small step in the programming of that model which was nicer than this one, but it was so minor I don't even remember it anymore.  The downside of those two (purchased at the most giantest retail Mart of Wals that is every retail snob's favorite store to hate - before we were subscribed to Amazon Prime (which is why I bought this one thru Amazin' Amazon)) was they had a "sport" wrist band that was part woven fabric, which stayed wet for a couple hours after getting out of the shower.  The band on this W87H-1V is plastic/rubberized so no issues with getting the cuffs on long sleeve shirts wet getting dressed after a shower.  The battery in these watches seems to last about 4 years with an average of 1-2 ILLUMINATOR button presses per night.  I HAVE used this watch to read by in a perfectly dark room.  That's how bright the ILLUMINATOR is.  Another reviewer also wrote a bit of genius about this watch: "the great big, easy-to-find-when-half-asleep button that operates the light."  AMEN and thanks for that bit of wisdom, stranger55 "Fred"!
