El reloj y todas sus funcionalidades están excelentes. La Correa no es de la calidad deseada debido a que se rompió a los dos días de uso. El plástico estaba viejo.

The watch works great

I bought this watch as a gift for my grandmother but I tried it out for a few days before giving it to her to make sure it does what it claims in the description. If you are looking at reviews of other watches here on Amazon, you will likely notice that the photos in the listing do not match the photos in the reviews. This one looks exactly like the one in the photo and is completely as described, no baiting and switching or false advertising!
I have a small wrist and this watch was not too big for me. The band has a really nice soft texture and feels sturdy. If you search for "20 mm watch bands" online, you can find plenty of options to swap this one out for. It works just like the standard name brands where you pull on the little pins to remove the watch bands and replace with other ones. I have already purchased some of the slimmer style silicone ones as my grandma indicated they might be more comfortable for her since she is used to a more petite watch.
The touch screen does come with a screen protector pre-installed that has two layers, one of them peels off with the little sticky tab that you'll see when you open the box and the other one remains on the screen to protect it. I did not notice it was two layers when I first opened it and before I peeled off the extra layer, it was really difficult to use the touch screen, but once I realized and peeled off the second layer, the touch screen is very responsive. When you grab the sticky tab, pull gently but somewhat quickly to ensure that the top layer peels off with it instead of peeling carefully and slowly and removing only the sticker like I did.
The brightness of the screen even on the lowest setting is pretty bright, so I recommend turning off the auto screen wake feature at night time.
The screen that shows many icons at once is almost useless because the icons are too tiny to click without a stylus, even my pinky finger was too big and it was too difficult to select anything. If you use the list menu instead, it is much easier.
The main reason I bought this watch was because you can make and receive phone calls from it, but that feature is a bit odd. If you answer a call from the watch it doesn't always connect to the watch speaker so you have to be within earshot of your phone, but if you make a call from the watch you can hear and speak into it. The speaker on the watch is really good and has plenty of volume.
I do wish there were more options for the customizable watch faces because you can only have one custom watch face and you are stuck with the other four options. The app allows you to search through many options, but it does not load very well so it is incredibly difficult to use. Luckily, the 4 default watch faces are pretty good and easy to read.
I personally have a Fitbit Versa 2 and I'm used to the button being on the left side of the screen and this watch has it only right side instead, so that could be potentially annoying if you are right-handed and wear the watch on your left wrist or if you are used to a Fitbit like I am.
I ordered the light pink and gold version and the colors look lovely and if you don't look very closely it can definitely be mistaken for an apple watch or another expensive brand. The watch itself is not too thick or too thin so it feels sturdy without being bulky. The screen bezel is pretty thin unlike some other affordable watches, so the majority of the watch face is actually screen instead of wasted plastic space.
I was unable to test this product for too long since it was a gift, but I did wear it overnight a couple times and the watch lost less than 10% battery, so I can see it easily lasting 3 to 7 days as other reviews have said. The charger has a magnet but it isn't a very strong magnet so you need to be careful to make sure it remains connected. It is pretty quick to charge and seems to hold the charge well. If you press and hold the button you can power the watch on and off.
The app that they show in the instruction packet was easy to download and pretty easy to use. There is an option on there to look at GPS tracking, but I'm pretty sure that's based off of your phone GPS because this watch does not appear to have a built-in GPS system. I did not get a chance to try out the fitness tracking options, but if you look at the app and in the watch there are plenty of different options. These step counter itself seems to be slightly unreliable, but remember this is a watch so shaking your arm will count steps as is to be expected with any brand.
There is a so-called game included on this watch, but I could not find any instructions on how to play it or figure out how to work it at all.
As other reviews have mentioned, the sleep function is not very accurate as it does not measure restlessness like a Fitbit. It just measures starting when you stay very still until you start moving again, so it might claim you slept for 10 hours even though you only slept for seven and it will not show if you wake up in the middle of the night and fall back asleep.
The heart rate monitor seems pretty accurate and I was not able to test most of the other monitoring features so I cannot speak to those.
Overall, for the price I think this watch is absolutely worth it. But if you are looking for more of the fitness luxury features, you would likely prefer a flagship product from a name brand.
For my grandmother, the highest priority was being able to receive calls and make calls from her watch at case of emergencies, so I was very happy with this product.

I was pleasantly surprised by how good this watch is for the price. It does everything I need it to. The battery life is pretty good too! Great for a first time smart watch user.

I love this watch but.... I think it could be better. There are NO instructions so I really don't know how to use all of the functions. So I basically just use it for the time without looking for my phone and to answer a call coming in. And I love how I can add one of my pics as the background.
