I have an F-91 and the thing I dislike about that watch and watches like it are the 3-button design. There's a pad for the fourth button and some functions could have been easier with a fourth button, but it probably increased the bill of materials by $1. Not sure why, but the 3-button asymmetry just feels wrong to me. Timex has a similar watch with 4 buttons and when my Casio dies, I'll probably buy one.
