GBX100-1

Excelente producto.

Good looking style, not bulky at all. Perfect display!! The interval timer functionality is really cool, and the sunrise sunset / tide info are all very helpful. Very cool watch!!!

I have had a lot of Casio watches and generally love them. This one has a lot to recommend it, particularly if you are a bit skeptical of the whole "smart watch" idea. Good things: (1) Reasonably accurate step counter. I've compared this to my wife's smart watch when we have both been doing the same activity and her steps and mine tend to track very closely. I don't think any of these things are perfectly accurate, but the algorithm and sensors in this seem to perform about as well as in more expensive smart watches. In other words, it works well enough for what you actually care about, a rough estimate of how active you've been. (2) Two-year battery. I have enough things in my life that need constant charging already, I like that the watch just takes a standard lithium battery that only has to be changed about once every two years. Maybe it only lasts a year, maybe it lasts 18 months, but whatever, it doesn't need to be charged every few days. (3) Bluetooth notifications. It synchronizes to your smart phone over Bluetooth and vibrates when you get an alert. There is no customization, if your phone gets an alert, it buzzes. But I've already gone through my applications on the phone and turned off all the dumb alerts I don't care about, meaning it only vibrates because I've gotten a text etc. So you can use it to vibrate and let you know you need to check your phone but only if you first configure your phone notifications to eliminate the useless ones. (4) Comfortable Band - This is a better quality strap than what you expect from a relatively inexpensive Casio watch. It is soft and pliable. (5) G-Shock Tough - I haven't abused it yet, but it is typical G-Shock stuff, unlikely to die even if treated roughly. I am a big dude who can carry off a bigger watch without looking stupid, but I would rate this as sort of medium+ size. In other words it might be a problem for very small/thin guys, but if you are of average/normal size, it likely isn't going to look stupidly huge on you. Dislikes: (1) Negative display. I bought this figuring that the size of the display would compensate for the fact that negative displays are inherently harder to read. It does, but only sort of. When you have it showing just the time and the time is huge, you can generally still read it in light shade or shadow, but if you want to look at anything else, it becomes difficult to do without hitting the light button, there is just not enough contrast for the small text. So if you are used to having a regular display, you will find yourself using the light a lot more often than you are used to. Basically, you need at least some direct light on the watch face to be able to read anything but the time, and that turns out to be less available than you expect it to be in the real world. There is a setting that automatically lights up the display briefly when the accelerometer detects that you are probably trying to look at the watch, which is essentially an admission that the watch is hard to read without the backlight frequently. (2) No large step counter display. The single screen that shows your steps is poorly designed, with too much information displayed at one time. It has a little bar graph showing whether you've hit your programmed goal for each of the last seven days. Then it shows your steps in very small numbers and it shows the time and the date. That seems nice, except go back to point (1) which is that it can be difficult to read small text on the negative display in poor light. Probably 90 times out of 100 when I look at my watch, I don't need to know how far I walked last Tuesday, I just want to know either my steps for that day or the time, and so there should be a second screen which has just that information in larger print. I do like the design of the weekly tracking screen, but it shouldn't be the only way to display that information. I haven't tried to use the advanced activity tracking features and I probably never will. I just wanted a durable watch to track my steps and this is a much more cost effective way to get that than buying a smart watch. If, like me, you have never had a negative display watch before, realize that they do take some getting used to.

I really like this watch! The tide & moon graph, the world time is great. The app is really great, I have not had any problems with it keeping it connected to the app. Very easy to see the time. I like how you can put it to sleep mode, saves battery. I know it’s not solar but I don’t think that will be a problem. If I can get almost two years battery life that is awesome!! I already own 6 Casio G-Shocks & will add to the collection. Recommend this watch!! Update, the brush aluminum will scratch very easy like Watch Collector mentioned. Just have to be careful if doing any work wearing it. But it is a great watch👍

The Casio gbx100 presents an attractive design, particularly suitable for smaller wrists like mine. While it doesn't function as extensively as a smartwatch, its occasional Bluetooth features serve my purpose, although I find the menu somewhat cumbersome. I connect it to my phone around twice a month, primarily for activity tracking and adjusting settings through the app, which proves more user-friendly than navigating the watch's menu. Attempting to receive messages on the watch proved challenging and, consequently, a feature I seldom utilize. During daily surfing activities, it exhibits impressive durability, showing only minor scratches after over three months of use.

impossible to read the time with this display technology. its so hyped up that everyone assumes legibility isnt any issue. this is a horrible lcd display (too small fonts) and making it worse, its all black. like i said, if you want a watch that WONT tell you the time, this is the one for you so sadly my review is -1 star.

It was brand new no damage 100% original

The good: • It looks very good • It’s comfortable • It’s accurate (with a catch) • Nice display • 200m water resist Missing features that other $30-ish Casio watches have: • Chronograph only counts from seconds (no tenth, no hundredth of seconds, seriously Casio?) • If you adjust the time manually you can’t reset seconds to sync with another watch, the only way I found was syncing through the phone :( • I couldn’t find any way to review next tide cycles, no way to easily browse through different days, similar limitation with the lunar phases. • Power saving mode is very limited, it only allows to turn the display off for a maximum of 3 hours per day, other Casio watches allow to stay in sleep mode indefinitely. • Push-buttons don’t have auto repeat so you’ll find yourself pushing the pushers many (many) times. • Custom tide setting is cumbersome for no reason. The hardware of the watch seems good, all these limitations are due to a poor written software.
