Casio W-71

Some time ago I found that some people was trying to figure out what kind of wrist watch was using Napoleon Dynamite. He was using a Casio. That is clear. Everyone seems to agree on that fact. Nevertheless, there is no agreement on what kind of Casio appeared in this movie.

Some people implies that Napoleon used a Casio W-71:

Others think that it is about a Casio W-59:

Even more, it has been suggested that the watch seen on this film is a Casio F-91W:

I decided to see the film again paying attention to the wrist watch. Here what I found:

Definitely: Napoleon Dynamite was using a Casio W-71. No doubts now.

Here some information about this watch:
