The watch functions are ideal:
it is water resist,
the time and date are on permanent view,
Mode: 12 or 24
fashion: light to read the time even in the dark
Mode: alarm and beep each time (off)
fashion: chrono
The easily adjusted using the 3 buttons.
It's comfortable, I do not feel. The bracelet does not pull hair. This rule without jeweler tools.
The closure system is well thought out, it does not open.
It was delivered on his Casio in support with the instructions in French (other languages also) and Casio guarantee.
I recommend this product. No possible disappointment.
