Casio does it again!!
Great watch. Looks very good. The only reason it does not get 5 stars is because of the bracelet. But because of the price it’s a great buy. My wife loves it..

Is am excellent choice if you want a simple, elegant, and durable watch. The blue dial looks striking without being too flashy, and the time is very easy to real. It’s lightweight, comfortable on the wrist, and keeps accurate time. The build quality is exactly what you expect from casio solid and dependable. A gread option for everyday wear or as a practical gift.
