I was unclear on the differences between the Casio F91W and A158. I bought one of each to compare in a hands-on review. Click to check it out.

Note

Okay, I am now fully involved in the Casio bubble, as I now own two Casio models.

The main reason for this is that I am really anticipating the upcoming Ollee watch shipment and thought that the A158 looks better. The main difference between the two models is the material. That’s all. Even the backlight is still shitty.

Beside that, if you don’t like the kind of cheap look of the F91W (well, it looks cheap because it is cheap), the A158 definitely scratches that itch.
