The Casio F-91W is the classic digital quartz watch that everyone has probably owned at some point in their life.

Reliable and simple, basic in it's beauty.

The only shortcoming of this standard of standards is its light and nighttime visibility. The light is only useful in the darkest of dark settings.

There is a reason Casio sells 3M of these a year, they just work to tell you the time/dare/alarm/chrono at the cost of under $18.

The cpmmunity considers this watch the GOAT, but I have my thoughts.

Yes, it is fantastic for the price you pay: 7 yr battery, 3 BAR water resistance which has been proved to hold even more than that. An absolute beater, cmfortable and easy to use.

My two downs are the strap, which is very clamsy and will break soon, and the backlight wich is very bad. Besides from that is a great watch. 

There are better models than this one as a beater, like W217, W108, F105, F59, F84 and some ohters, but his F91W is a piece of history you must have in your collection, or to give as a gift to a child or an elderly persona who wants a reliable, resilient and good piece of time keeping.
