Simple and perfect
I love the classic simplicity of this watch, and how light it is. I got the blue one -its a stylish navy blue. The face is very clear. The alarm is loud enough without it being piercing. The price is excellent considering all of this and how the battery lasts for years (I can vouch for this as I have had a similar Casio watch and have yet to change the battery after 8 years).

Great watch!
This is the 3rd one of these that I've bought. They work fine & keep going. It was the strap that failed on my my original one, the watch still works and its so old that I can't remember how old! (I lost the 2nd one.)

Looks good. Comfortable. Does everything you need it to.
Bought for my husband who loves a bit of retro. However, my teenage son who didn't get on with the latest flashy watches that are far to heavy on his wrist now wears it. It's looks better too. I'll need to buy my husband another one now!

Great first watch
Bought for my daughter whose favourite colour is blue. Typical Casio - well packaged, high quality and looks good. My daughter really loves this watch. Highly recommended.

For smaller wrists
Small strap not great for men with large wrists.
