Review: Cheap price but works great - Use it everyday as a EMT, perfectly simple, reliable, strong, and cheap. 3 years and no issues.
Review: Great everyday watch - I’ve been wearing this watch every day for about five months now, including to work, and it has held up great. I really like the sleek, simple look. It’s versatile enough that it looks good with a casual outfit but also works well with a uniform. One feature I use all the time is the timer for my lunch breaks. It makes it easy to keep track of my time and make sure I stay on schedule. After five months of daily wear, it’s still working great and has been very reliable. Definitely a great everyday watch, especially for the price.

## Questions & Answers

**Q: How are they charging $10 for this $3 watch from 1990?**
A: Anything that was $3 in 1990 is now $10.  Back in 1990 gas was $1.16/gal.  The average home price was under $150000.  As time moves on prices go up.

**Q: Does the count down timer be set to seconds?**
A: No countdown timer. Look at Model F201WA-1A for that feature.

**Q: how far in depth is the water resist**
A: If you want to be absolutely safe, get the Casio MRW200 dive watch which is good for 100 m.
Casio F91W is water resistant and you could take it in shower, swimming, etc.

**Q: The rubber band broke after 2 years of use. I love this watch and don't want to get a new one. Any tips for a replacement band? Maybe a nylone one?**
A: Aliexpress or ebay you'll find almost exact generic replacements for a couple bucks shipped. Search for words like F91W strap, 18mm watch band. You can also use normal 18mm spring bars instead of the pins that are stock with the F91W.

### ⭐⭐⭐⭐⭐ Works Perfectly!
*by A***I on September 28, 2026*

Extremely functional and convenient watch. I purchased it because I wanted to tell the time in class without having to pull out my phone, this watch has been perfect. It has not scratched and only lost 2 seconds of time in the month that I've had it. The material is durable and not uncomfortable. It is impressively lightweight and thin. Only flaws are that the alarm function is pretty limited and the light stinks. Other than that, highly recommendable for any time telling needs!
