We Tested the Nabu Watch

Wearable technology is the new girl in the industry’s eyes. Basically, everyone who can have a smartphone already has one, and focus has turned to creating accessories that orbit the intelligent cellphone. Hence it was born all the internet of things, and the already quoted wearable technology, which includes bracelets, eyeglasses and wrist watches.

The Razer is one of these companies that is diversifying their activities. The company specializes in computers and laptops for games, but today also produces the connected bracelets Nabu and, most recently, the Wristwatch Nabu watch, which I have had the opportunity to test in the last few weeks.

Notice that at no time I called the Nabu Watch “intelligent watch”. That’s deliberate, and you’re going to find out why according to VINTAGEMATTERS.

The appliance

Let me get this out of the way before we proceed: No smartwatch persuaded me until today. Its functionalities until today are restricted to a luxury that is laziness to remove the cellphone from the pocket. If you have the money for that, great, but it’s not a necessity for most people, making the appliance superfluous.

That said, the Razer Nabu is not a smartwatch. It is a digital wrist watch, very close to any other you have seen before inventing the smartwatch expression, with the differential of being a clever bracelet, able to collect data about exercises, calories burnt, monitor your sleep, serve as a pedometer and silent alarm. It also shows the notifications you receive on your cellphone.

He’s a smart bracelet with a coupled wrist watch. And he goes very well as a fitness bracelet.


You can’t deny the watch is big. Pretty big, actually. As soon as he arrived in the Digital look, they began rolling the notorious jokes with “inhaled time!” of the Power Rangers, or the inevitable comparison with the watches used by the glorious presenter Faust Silva, the Faustus.

It’s definitely a masculine design, since women’s watches are usually more delicate. It is large in circumference and is also thick, which makes the fitting in the fist not very natural, and requires a period of adaptation for those who are not accustomed. It tends to restrict the hand movement a bit because of the exaggerated size.

It’s worth remembering what was said above: The watch is a fitness bracelet that measures sleep. That means you’re encouraged to use it while you sleep. Unfortunately, it was quite uncomfortable to use it to sleep, as interesting as it is the idea of measuring the quality of your night nap.


The Nabu watch is virtually all configurable by the cellular, through a Razer application, which connects to the watch via Bluetooth. The configuration is fairly painless, although the application is not a primer in usability. It could be a little simpler to use and have a slightly more elegant layout.

The application concentrates the data collected by the bracelet, which summarizes in five main groups: The amount of steps you’ve given over the day, the distance you’ve traveled on your walk, how many calories you’ve burnt in the process and how long have you actually been active during the day. In addition, it shows how many hours you slept during the night And the amount of times you’ve been without rest while you were sleeping because you were restless.

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

By screenshot, you can perceive: I’m not an example of an active human being. Most of the time I spent far from hitting the goals that the application offered to me, which is part of the purpose of wearing a bracelet of the type. Create goals, overcome them and establish new ways to live a healthier life. Unfortunately, she didn’t bother me enough to force me to get my out of the chair, but there was a day that I needed to walk a lot and hit the goal. At this time, the bracelet vibrated and showed a little trophy in the small OLED viewfinder. I’m not going to lie: it was fun.

This OLED viewfinder that is really small, also has another interesting function, which is to show the notifications that arrive on my cellphone. Unlike other watches (the smart ones), it does not allow you to take any action on it. You can only see them and discard them without any other possibility of responding except to take the cellphone out of your pocket. Still, it’s more practical than getting the smartphone out of your pocket every time you feel the vibration.


Something that should be said about the Razer watch is the duration of your battery. As he is not a clever watch in the most conventional sense of the term, he does not suffer from the same battery-burdens as his brothers like the 360 motorcycle or the Apple watch, which hardly resists more than one day without recharging. No, the Nabu Watch exceeds a week of use without needing a new recharge, and that’s great. Moreover, the recharge is also very fast, going from 0 to 100% battery in about 2 hours.

When you really need to upload, 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 connector, similar to the MagSafe we found on the MacBooks. The fitting is very simple and facilitated thanks to magnetism.

The magnetic connector only has one possible problem. Because it is a proprietary connector, you must hope that the battery does not end 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 does not stop working. It sounds crazy, but it’s pretty simple, actually. Remember we said the product was a smart bracelet with an attached wrist watch? What stops working with the end of the battery is the part of the intelligent bracelet; The conventional digital clock is still operating normally for undefined time. That means that even if you are the most forgotten person in the world and stop loading the appliance for more than a week, you will not be without hours.


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

The bracelet also talks with other apps, including Facebook, Twitter, Google Fit and the My Fitness Map. The Razer must also launch a development kit so that other applications embrace integration with their appliance shortly.

The company has never concealed that its origin is in the world of games, and the bracelet can also help players. The Razer speaks in the possibility that players can get extra scores and advantages in games when hitting their goal of steps in one day, for example, although not giving a concrete example of a game that has or will come to have this functionality. But it’s a good idea to encourage the public to move.


The Nabu watch of Razer is not a smartwatch, it is not a smart watch. It’s a bracelet connected with a coupled watch, and it’s good for your job, as long as the buyer knows how to differentiate the two things.

The big problem, however, is the competition. The fitness bracelets market is flourishing, with some prominent options. An example is Mi Band, from Xiaomi, which costs less than R $100, making most of the functions that the Nabu Watch does; It just doesn’t show the time, nor has the small screen to display notifications. Meanwhile, the Razer’s watch should reach Brazil by R $1000, according to the company itself.

So the Nabu watch is only for those who want the functions of a bracelet, but they do not open hand of the expensive digital wrist watch. For any other option, the Nabu Watch doesn’t make much sense.
