## Questions & Answers

**Q: Please can somebody tell me if it will fit a ten years old child?**
A: The long side of the watch band has holes all the way to where the buckle nearly meets the body of the watch.  The band can be adjusted down to a wrist that measures 5.75 inches around. It looks a little odd adjusted all the way to its smallest size so if the kid has some meat on him and not too slender (like I was) it will be fine and he'll grow into it. It's an X-large watch face so if the child is quite slim this watch will just make it more aesthetically obvious as it hangs off the little guy.

**Q: How do you adjust the Analog hands? I dont see a dial for them.**
A: You can calibrate the watch hands by holding adjust button until the 2nd beep. Once engaged, make sure both hands are exactly at the 12 o’ clock position, then press adjust again to return to the time screen.

**Q: the advertising says the band is black but the pictures show the band being another color. which is it?**
A: The band on the one that I bought is black. Same color as the face.

**Q: What is the difference between an Xl and regular sized G-shock watch?**
A: Honestly, I don't think there was a difference.  I bought this and it turned out to be the same size as the other men's G-Shock watch..

Buen reloj, lo único malo como en todos los modelos G-Shock de la serie GA de tamaño grande es la pésima iluminación
