I love the indiglo watches.  I have been buying them for years.  In the middle of the morning when you wonder what time it is you just have to push the button and you can go back to sleep because you didn't have to turn on the light to see the time or get up to look.  I have several and when the indiglo quits working (as it does after a number of years) I just get a new one and use the ones without the "night light" to work in the yard.
