    A month ago, I saw a video on Youtube that reminded me of this watch's existence; I remembered my friends wore it back when I was in high school. I immediately realized I must get it...

    Its basic water resistance seemed like magic back in the olden days (Wow, look, it still works in a glass of water!) and it has a stopwatch that measures hundredths of a second AND IT HAS A LIGHT! Don't laugh, I am Gen-X. I made my own toys from carboard and scotch tape when I was a kid, I know how to use rotary phones and do research from books.

    This watch came out just after the proper cyberpunk era of the 80's and it was omnipresent - everyone had one as it was cheap, not-ugly and did its job perfectly. You can even play the "double zero" quasi-game: run the stopwatch and try to stop it exactly when hundredths show 00.

    This was and even today is a really handy device. It does not matter if you are a kid in the elementary school or a soldier, this watch will serve you well. It looks retro-awesome, it is reliable, pretty resistant to damage, it will survive a shower and even a short swim. Ultimately, if it gets destroyed, no biggie - just get another one or three.

    The most ridiculous thing is that since I bought it a week ago, I had already two people tell me it's awesome!

    Life is about small indulgences.

    I'm not a fan of watches that look like a dinner plate on your wrist. If you agree, you might like this watch

    Never been a watch guy, but this Casio changed that. Now it’s the most exciting part of my morning routine—strapping it on just feels right.

    Simple, reliable, and that 10-year battery life? Unreal.

    I originally got into it because my late grandpa had one, and restoring his was a special project. But it’s too precious to wear daily, so I picked up this one instead. It’s the perfect neutral watch—goes with everything, feels effortless to wear, and now I can’t imagine a day without it.

    The light on it sucks, but it's not a big deal. The timer and stopwatch and such work well, and so does the alarm. I use it everyday at work, and I do a lot of lifting / moving, and it's gotten caught on a number of boxes / furniture and it somehow still hasn't broken the band. Actually very surprised considering some of the boxes I've gotten it caught on and yanked have been quite heavy. Can't go wrong with a budget classic!

    I love Casio F91-W. I loved the grey-coloured dial with black strap. The accuracy and ease of use is just sensational. It is highly waterproof resistable, durable (able to withstand accidental jolts and shocks) and works perfect. It is really a value-for-money watch and hence it's popular

    Es bonito y funcional, se siente de relativamente buena calidad, pero (por el precio es obvio) no es original, y la luz no es muy eficiente al iluminar en la oscuridad.
    Lo compré hace ya 5 meses, y no he tenido ningún problema, es bueno.
