  • Love the watch, fits great.
Little difficult to figure out how to switch time/date. But, there’s videos for that. Also love the tin container it came in lined with soft material so you can keep it safe when not wearing it.

  • As described.
Love the GA2100 range from Casio. Not too big and looks good for all occasions.

  • Nice watch
A little smaller than the other G-Shocks I have bought however, it's a nice change of pace and is dressier. Looks great in my opinion.

  • Nice watch
Nice watch but ended up returning because the face was too small

  • Watch is excellent, band is cheap.
Love the watch. Watch band, on the other hand, is absolute crap. You will want a different watch band- just assume that you will have to pay the money for a different watch band.

  • Un poco complicado para activar las horas pero es buen reloj
Solo tarda demasiado en llegar y no llega en tiempo indicado en el pedido.

  • Watch is difficult to set different functions.
I didn't like the instructions to set the different functions. They need to be simplified so someone who is not tech savvy can set their watch. I love everything about the watch it's just hard for me to set functions following the instructions. Also watch should come with instructions in English.
