GSTB400-1A

I really wanted a daily driver watch that could handle abuse, so of course I turned to Casio G-Shock. This watch is a beauty to behold on the wrist, the pictures don't quite do it justice. I love all the features on this watch, especially the solar power and bluetooth connectivity. I've had it for a few weeks now and it's never indicated less than a full charge, even when left for a few days on the nightstand with low or no light. It syncs the time automatically with my phone a few times each day, so I never have to worry about setting the time.The one gripe I've seen a lot of people express, which is valid, is that the negative displays on the 2 small digital readouts is a bit dark when in low or indirect light. Outside or in the office, I can read it fine. However, it does have a button for an LED light and backlight on the displays, so if you need to read them you just need to press the Light button. I've even used the LED light a few times to find my way in the dark (it's way brighter than a smartphone screen). I don't find it to be a problem, but I can understand how some would consider the negative displays as a drawback.Overall though, I really love this watch and can't recommend it enough!

My husband loves this watch! He hasn’t taken it off since he got it. It looks awesome and has some great features, even a light so you can always tell the time.

The digital parts are a little difficult to read and it takes quite a while to change. However it is accurate and easy to sync with the phone app. This is the third G-Shock l’ve owned and all have been really reliable.

Just got the watch today, so this isn't a full review...yet.The watch is smaller than I expected. The width isn't listed in the description, but I had read somewhere 49.5mm. I haven't measured it, but it's about the width of, maybe a little less than, another watch of mine that measures 45mm.It's still a beautiful watch. I hope the strap holds up and doesn't split like a similar strap on a Nautical watch I had.STAY TUNED.

I had a hard time to choose between the gst b100, gst b200, gst b300, gst b400, bst b500 and finally the gst b600. To my eyes, the gst b400 represents the 'perfect' middle point where the watch is not too big nor too small, not too simple ( the watch face ) nor too busy/sporty. Per example, I do like the b100 but it is too bulky ( for my small wrist ). I do like the b600 but I find it too much simple ( the watch face ). Don't get me wrong, I still do like both of them because in fact there are well done. My target was a G-Steel with a great, bold-3D look ( is this term my invention ?, lol ) but not too big/bulky and the 400 serie is right on spot. I put the score of 4/5 stars, in fact it would precisely be 4.5/5 and then I can say that I removed 1/2 star because I really think that Casio should have made the hour index markers with lume, a 'missed' opportunity considering the fact that there is largely enough space too to do it. Maybe it is just my personal taste but I don't think so. But still, it is a good watch ( solar + bt + all the classic features of a G-Shock ) and the look of it is a big 👍.

Nice watch as noted in other reviews some reading are small and hard to read but still ok.

Comfortable,light,durable. I love that it syncs to your phone so the date and time is never wrong.

I'm greatly Disappointed in the design with this watch.The digital readout is difficult to see, that little razor wheel is pointless and clutters the face, for some reason the light is at the 5 o'clock position so it only lights up part of the watch face, there's no auto light, and the "find my phone" feature is only good for up to about 10'. If your phone is in another room or outside this feature won't work at all. Unacceptable for a watch at this price point.

Casio Watches app is intolerable, intrusive, offensive. Will not buy Casio bluetooth ever again.

The media could not be loaded.  El reloj queda Perfecto tengo una muñeca de 16.5 cm y no queda demasiado grande queda muy bien . El estensible es suave y no es un reloj pesado. Es mucho mejor que el que es de extensible metálico ya que esté pesa la mitad . No estoy arrepentido y tiene además una luz que permite ver con claridad la hora y aplicaciones .

The media could not be loaded.  Es un poco más pequeño de lo que se ve en foto, pero aún así es muy bonito el reloj, es brillante el acabado y se ve genial en tu mano, muy recomendable.

Es Casio, es G-Shosck, es un buen modelo en general, buena construcción, muy ligero, muchas funciones,hora mundial, cronometro en Lap y Split, timer regresivo, 5 alarmas y señal horaria, tiene bluetooth, es solar, no le hace falta nada, sin embargo los displays negativos son problemáticos, no se ven bien a simple vista se necesita verlos con suficiente luz, se agrega que el diseño mismo de la esfera bloquea mas la vista de los displays, por suerte el reloj tiene luz incorporada de doble led, tanto para la esfera como para los displays si no fuera por esto, le daría 3 estrellas de calificación.
