We Tested The Nabu Watches

Wearable technology is the new pride of the industry. Basically, all of which can have a smartphone already has one, and the focus turned to the creation of the smart phone accessories that orbit. From this was born, the whole internet of things, and the already cited wearable technology, which includes bracelets, sunglasses and watches.

Razer is one of these companies are diversifying their activities. The company specializes in computers and laptops for gaming, but today also produces the bracelets connected Nabu and, more recently, the Nabu wristwatch Watch, which I had the opportunity to test in recent weeks.

Note that at any time I called Nabu Watch of “smart clock”. This is deliberate, and you will find out why.

The appliance

Let me get this out of the way before we go any further: no smartwatch clock convinced me to this day. Its functionality until today are restricted to a luxury that is too lazy to take the phone out of your pocket. If you have the money for it, great, but it’s not a necessity for most people, making the device superfluous.

That said, the Razer Nabu is not a smartwatch clock. He is a digital wrist watch, very close to any other you’ve seen before they invented the smartwatch clock expression, with the difference being a smart bracelet, able to collect data on exercise, calories burned, monitor your sleep, act as a pedometer and silent alarm. It also shows the notifications that you receive on your cell phone.

He’s a smart bracelet with a watch attached. And he does very well as bracelet.


You can’t deny that the watch is great. Well great, actually. As soon as he arrived in the Newsroom of the Digital Look, started rolling the notorious jokes with “time to Eat!” of the Power Rangers, or the inevitable comparison with the clocks used by the glorious presenter Fausto Silva, Bill Murray.

It’s definitely a masculine design, since women’s watches tend to be more delicate. He is large in circumference and is too thick, which makes the fitting on the handle is not very natural, and requires a period of adjustment for those who’re not familiar with. He tends to restrict a little hand movement because of exaggerated size.

It is worth remembering what was said above: the clock is a bracelet that measures sleep fitness. That means that you are encouraged to use it in your sleep. Unfortunately, it was quite uncomfortable to use it for sleep, for more interesting than is the idea of measuring the quality of your night NAP.


The Nabu Watch is practically every cell, configurable through an application of the Razer, which connects the clock via Bluetooth. The setting is pretty painless, although the application is not a masterpiece in usability. It might be a bit simpler to use and have a layout a little more elegant.

The application focuses the data collected by the bracelet, which summarize in five main groups: the amount of steps you gave during the day, the distance you traveled on your walk, how many calories you have burned in the process and how long have you actually been active during the day. In addition, it shows how many hours you sleep at night , and the amount of times you’ve been relentlessly in his sleep to be restless.

It was possible to observe that the sleep meter does not measure your sleep really, but your period lying in bed. In more than one opportunity the bracelet has detected a false positive when I was watching something on TV in bed. It made me question the quality of the data that were presented at the end of each day.

For the screenshot, you can see: I am not an example of active human being. Most of the time I spent away from hitting the targets the application offered to me, which is part of the purpose of using a bracelet of type. Create goals, overcome them and establish new ways to live a healthier life. Unfortunately, it didn’t bother me enough to force me to take the back of the Chair, but there was a day when I had to walk a lot and hit the goal. At this time, the bracelet vibrated and showed a little trophy on the small display of OLED. I’m not going to lie: it was fun.

This OLED display that is really small, also has another interesting function, which is to show the notifications that arrive on my phone. Unlike other watches (smart), it does not allow you to take no action on it. You can only see them and discard them, without any other possibility to answer except to take the phone out of your pocket. Still, it’s more practical than taking the smartphone of your Pocket every time you feel the vibration.


Something must be said about the clock from Razer is the duration of your battery. As he is not a smart watch in more conventional sense of the term, he does not suffer the same ills of battery that your brothers as the Bike 360 or Apple Watch, that hardly resist more than a day without recharging. No, the Nabu Watch overcomes a week without needing a recharge, and that’s great. Moreover, the rebound is also very fast, going from 0 to 100% battery in about 2 hours.

When you really need to carry, the Watch has a special trick, which we also see in the most prominent smartwatches. Instead of using a conventional micro-USB connector, it uses a magnetic MagSafe connector, similar to that used to meet in Macbooks. The plugin is very simple and easy thanks to the magnetism.

The magnetic connector has only one possible problem. Because it is a proprietary connector, you have to hope that the battery runs out while you are on the street or at work; otherwise, you will not find a suitable cable to recharge the appliance. Fortunately, as the battery life of the Nabu Watch is long, this scenario is unlikely.

Another advantage is the fact that, when the battery runs out, the clock is working. Sounds crazy, but it’s quite simple, really. Remember we talked about that the product was a smart bracelet with a wristwatch coupled? The crashing with the end of the battery is the part of the smart bracelet; the conventional digital watch follows running indefinitely. That means that even if you are the person more forgetful the world and fail to load the appliance for more than one week, you won’t run out of hours.


The clock on the Razer brings some interesting ideas such as the “handshake”, or “handshake”. If two people greet you, both using the clock (or another bracelet Nabu), each receives the contact information of another. That, of course, if the two people have activated the tool, which is turned off by default.

The bracelet also talk with other applications, including Facebook, Twitter, Google and the Map My Fitness. Razer must also launch a development kit so that other applications embrace integration with your device soon.

The company never hid that your source is in the world of gaming, and the bracelet can also help players. Razer speaks in the possibility that players can get extra score and advantages in games to beat your goal of steps in one day, for example, although he did not give a concrete example of game that has or will have this functionality. But it’s a good idea to encourage the public to move.


The Nabu Watch Razer isn’t a smartwatch clock, is not a smart watch. It’s a bracelet connected with a clock attached, and good for your function, since the buyer knows how to differentiate the two.

The big problem, however, is competition. The market of fitness bracelets is blooming, with some options. An example is my Band, of Xiaomi, which costs less than 100 R$, making the most of the functions the Nabu Watch does; not only shows the hours, nor has a small screen to display notifications. Meanwhile, the clock on the Razer must reach Brazil by R$ 1000, according to the company itself.

Thus, the Nabu Watch is only for those who want the functions of a bracelet, but not give up the expensive digital wristwatch. For any other option, the Nabu Watch doesn’t make much sense.
