One of the best looking G-shock.
Probably the best looking G-shock in the price cap. Especially the thin octagonal dial with all black bezel takes all the attention. However, the time visibility is low outdoors. Rest its an awesome watch to own.

Everything I wanted.

Un diseño simple pero al mismo tiempo llama mucho la atención sin necesidad de ser un reloj robusto y de diseño extravagante. Funciona excelente y muy fácil de configurar, lo único que deja mucho que desear es la presentación, esperaba algo más que una simple caja de cartón muy delgado, pero eso es lo de menos, fuera de eso me encanta.

I have to keep this at 5 stars because it really is a great watch despite the readability. Once you’ve gotten bored of your Swiss watches and want to wear something different for a day or two, it’ll probably be one of your favorites to wear. On readability, it’s not the best. But if we’re being honest, that’s not really the point of this watch. This is just a great looking watch that will pair really well with very casual dress.

Awesome watch and very sleek. Definitely one of the most comfortable G shocks due to the thin profile, but still feels rugged and cool. A downside is the visibility in low-light environments, but that's why you get the LED light. Definitely one of my favorites.

Very small face. Ideal for a child but not a large man.
