Great watch for the price.
I adore this watch, feels lightweight, love the alarm and stopwatch feature and looks awesome. The watch hands have lume and it looks very nice and bright in the dark, the light on the watch is helpful for the dark evenings. I am looking to modify this watch and change a few things as my first custom watch, but just the green and black itself as standard looks really cool. Great value for money; I can highly recommend.

Great watch, hard to read
Fantastic watch overall, solid, durable and very lightweight. I actually bought it so I could do a casioak mod on it with a metal strap but I ended up leaving it as it is because it looks great. You can't read it very well unless you're in good lighting in honesty, the only downside.

Illumination
Nice watch and eye catching. Just beware that it works best outdoors. In daylight the display is great. Indoors not quite so good. Still easy to read. But at its best outside.

Great watch
A great Casio G Shock watch for the price, with all the usual functions. Strap a bit thinner than the usual chunky straps with a G Shock, but no big deal .👍

Great watch.
I have had this watch for 6 months now and i'm very happy with it. I have quite large wrists and the watch fits my wrist very well. I often go swimming both inside and outside and so far, the watch has survived. Would definitely recommend.

A great looking slim G-Shock watch
I was looking for a casual watch to wear at the weekend. My current G-Shock and Pro-Trek watches are a bit too chunky to fit under a shirt sleeve easily. This one however with its "Carbon Core Guard" is slimmer and much more wearable. I love the looks of this watch. The contrast of the matt black face with the green hands and markers not only looks striking, but make it very readable. Low light visibility is also fine - the hands glow a vivid green in the dark and the LED light illuminates the face sufficiently and even the LCD display to some degree. It has the usual standard Casio features, including world time, alarms and stopwatch. Being shock proof and water resistant to 20 Bar, wearing the watch in less than ideal conditions is not a worry. The only minor criticism is that the buttons are a little hard to push, although these might free up with use. Overall a great looking and very usable Casio G-Shock. For me, it's a great balance of style and substance.

Lovely watch but poor illumination at night...
I bought this watch last week, it's really nice to wear and looks great. However it is difficult to read at night, the illumination on the hands is not great and the illumination at each hour mark is non-existant. I like it, but I don't love it.

Nice watch for active people
I bought this for my husband’s gift a couple years ago and he still loves it. Mainly because it’s very sturdy and doesn’t get damaged easily. It’s definitely a nice watch for people who are active because the watch is not too heavy and doesn’t get affected by sweats

¡Mi G-Shock "CasiOak" Verde: La caña de España!
¡Qué pasada de reloj, en serio! Me pillé este Casio G-Shock GA-2100 (ese que la gente llama el "CasiOak" porque se parece un poco a uno muy caro, pero en plan bien) y no puedo estar más contento. Lo tengo con los detalles en verde lima y, buf, es que le da un toque que flipas al negro mate. Lo que me mola (¡y mucho!): El diseño: Es que es guapísimo. Rompe un poco con la idea del G-Shock "ladrillo" de siempre. Es finito, no abulta nada y esa forma octogonal... Es que entra por los ojos. El verde de las agujas y las marquitas es un puntazo, se ve súper bien y le da un toque modernete que me encanta. Y mira que en las fotos no se aprecia del todo, pero en la muñeca gana un montón. Cómodo a morir: De verdad, no pesa nada. Parece mentira lo ligero que es para ser un G-Shock. La correa es blandita, se adapta genial y te olvidas de que lo llevas puesto. Ideal para el día a día, currar o lo que sea. Aguanta lo que le eches: Esto es un G-Shock, ¿verdad? Pues eso. Le he dado golpes sin querer, me he duchado con él y ahí sigue, como un campeón. Es duro como una roca, y eso te da una tranquilidad que no veas. Las funciones: Tiene lo típico que necesitas: la hora del mundo si viajas (o si te apetece saber qué hora es en Tokio, jajaja), cronómetro, cuenta atrás, varias alarmas... Lo básico para el día a día, sin complicaciones. Se ve la hora digital genial, aunque a veces con poca luz hay que darle al botoncito de la luz, pero tampoco es un drama. El precio: Esto es lo mejor. Para lo bien que queda, lo que dura y las cosas que hace, es que el precio es de risa. Parece un reloj mucho más caro de lo que es, y eso siempre mola. Lo único "meh" (por decir algo): A veces, si le da el sol directo a la pantallita digital, cuesta un pelín ver los números, pero le das al botón de la luz y listo. Es una pijada, la verdad. En resumen: Si estás buscando un reloj que sea la bomba estéticamente, que te aguante carros y carretas, y que no te deje la cartera temblando, este G-Shock GA-2100 es tu reloj. Es el típico que te pones para todo y sabes que no te va a fallar. ¡Totalmente recomendable, un 10 de 10! ¡No me lo quito ni para dormir!
