## Description

This is a perfect sporty and business causal watch for you, it's a great gift for family or friends. This Digital watch has a calendar function: Day-Date , Stop Watch , Alarm and Light

Review: 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).
Review: 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.)
