Review: Great watch, easy to setup - This is a really fun and functional "throwback" watch! It looks just like the digital watches when I was a kid in the 80s. Got this for my son for travel because it doesn't look expensive, so hopefully it won't attract any attention. It's great that it's SUPER easy to use. My son was in a hurry and asked us to set it for us and I was pulling out the instruction manual, ready for a complicated setup but my husband grabbed it and had the time set in 30 seconds. And this is a great price for a good watch that is also water resistant!
Review: Get compliments at work! - An excellent digital wristwatch for work. The slim profile makes the watch almost weightless. The black and gold makes this classy but also makes it a low-effort thrown together feeling. As someone who has terrible vision even with glasses on, the digital clock makes it much easier for me to tell time with just a glance at my wrist. Casio is a household name, and bringing it back is a big conversation starter in my office. Simple, classic, reliable.

### ⭐⭐⭐⭐⭐ Amazing Watch, except a few things.
*by B***N on August 19, 2025*

This watch is absolutely AMAZING! It looks very unique with its own design but still manages to look nice no matter the occasion. The features are nice, I like the stopwatch but the alarm personally isn't loud enough for me, but that doesn't matter because most people don't use their watch for alarms. I haven't worn it enough for durability yet but it with stands scratches pretty well. The band is also very comfortable and easy to adjust. It's the perfect watch if you just want a watch not nice enough to be a rolex, but not smart enough to be an apple watch. Just time! And time is does incredibly well, it's very reliable, looks nice, and I forget I'm even wearing it. Okay here are the not-so-good parts, (this watch is perfect but here's what the picky people should look out for) The few times I need to click the buttons they feel weirdly uncomfortable to press and hard. Also, the backlight is VERY dim, I know it's too small to but a full backlight but atleast more than one LED. I have to squint to see it and the oppisite side you can't see anything. Doesn't come in clutch the few times I need to use the light.
