I bought this watch after wearing Casio watches exclusively for the past twenty-five years. Lightweight and comfortable, I am not aware of them until I take them off.  Rugged, inexpensive, and easy to replace, I have little concern about breaking or losing them, or having them stolen.  I only replace them when their bands break, because they are so cheap, it's not worth the hassle of replacing the bands, plus the watch face usually has scratches by then due to the rough treatment they get on the job. I bought this watch when the band broke on my Casio F-105, which I acquired when my eight year old daughter found it on a soccer field. This model is sleeker and has a larger readout, with more information displayed without pushing buttons. I like the month and date display, along with the day. The time display is taller, and I had hoped, more legible to my presbyopic (far-sighted) eyes, but because the numbers are the same width, they're actually harder to read. In addition, the light feature, called "Illuminator" as in the F-105 is weak (as noted in other reviews) and useless unless I'm wearing reading glasses, whereas the illuminated F-105 was legible to me (just barely) without them. Bottom line: great digital watch if you aren't far-sighted and don't care about the light function.
