Review: First Casio - Really happy with the black minimalist look they gave this. Very clean. This is my first Casio watch. I figured it was a good place to start. My wrist is just about 7in and I wear watches tight, so it doesn’t look terribly small imo. Did the aluminum foil mod to help reflect the backlight. Improved lowlight visibility noticeably (I accidentally scratched the inside of the watch face when doing that, which now lets that sliver of light through). Super light, and the optional hourly chime is a nice touch. It’s nice on days off when you want to be a little more present. Only downside is the price. I bought this at $37 and it’s really not worth it. I love the watch, but I would feel better looking at it everyday if it was $20, maybe $25 at the most.
Review: Casio F91 for the win - love me a Casio watch, relaible and works well. fits well and can't beat it for the price.

### ⭐⭐⭐⭐⭐ Excellent Watch
*by C***L on August 1, 2026*

I've owned much more expensive watches than this one but I really like this watch. It's very simple and easy to program. Simplicity has a place. I highly recommend this watch, but I recommend you buy a screen protector.
