Dream watch!
I love the product. It has a classy, rugged look which goes with most day to day outfits. It glows in the dark which makes it easier to tell the time at night. There is also a light button, and when you press it, it illuminates the dial. It is solar powered and all you need to do is wear it every other day to keep it going. The watch is simple and intuitive to operate and connects to the phone with bluetooth and auto syncs the time. I waited 6 to 7 years to buy a G-shock watch and i got it during the sale for an amazing price. I have been using this for 2 weeks now and i am very pleased with the purchase. Dream come true.

Great deal
Geniune product, recieved in a good packing. The bluetooth linking is working properly and the delivery was smooth and on time. The warranty needs to be registered online on or before 30 days of purchase. It is suggested that the invoice and warranty slip may be printed out and a copy kept at safe custody for utilitising warranty.

You won't regret buying one.
Sleek design with classic G Shock features, Bluetooth connectivity which makes it seamless to setup and significantly lighter. One of the better looking G-Shocks and with Solar it is indeed "Toyota of a watch"

Stealth G-Shock.
Was looking for a G-Shock for my watch collection which was not as bulky as G-Shocks tend to be(I am looking at you, MudMaster). This watch fit that criteria perfectly. It has most the features you would usually want. Has solar charging and bluetooth connectivity (though I am not using it via bluetooth). It is also surprisingly lightweight and feels extremely comfortable to wear. And it does that without feeling like a toy watch. And I quite like the understated all black stealth look. Currently, this has become my rotational daily driver watch where I wear this one every alternate day.

excelente
O relógio se destaca pela beleza, além disso é muito leve e confortável. Comprei para ser meu relógio do dia a dia e estou muito satisfeito. O recurso do bluetooth facilita muito a configuração e ajuste do mesmo através do aplicativo no celular. Esse modelo específico tem o mostrador todo preto e a tela de led negativa, algumas pessoas podem estranhar ou ter dificuldade para ler as horas, mas para mim não é problema e ainda acho que é o diferencial desse modelo.
