I feel like the F-91w is as much of a brand-driven symbol as the luxury watches. The F-91w has come to represent this scrappy, minimal, no-nonsense mentality - but it's not the cheapest watch you can get, and I don't think it's even the cheapest Casio anymore. It's more expensive than it used to be, so you need to go out of your way to pay more to get this specific model. Because customers know that people will recognize it, and that will better project the way they want to be seen.
