*by A***R on 6 February 2026*

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).
