The Razer Nabu Watch is a digital watch with smart features. Not a smartwatch, Razer has stressed.

It has a main digital clock face that displays the time and date, and you can toggle through different modes such as timer, stop watch, alarm and world time by pressing a button.

Below the main clock face is a small 128 x 16-pixel Oled screen. This is where you see the smart features like e-mail, WhatsApp, Facebook and Instagram alerts, when the watch is paired with your smartphone using the Nabu app (available for Android and iOS).

There is a command button below this small screen. Pressing it cycles through your steps taken, distance travelled and calories burned.

It doubles as a fitness tracker. It automatically monitors your daily physical activity and sleep. However, it does not have a built-in heart-rate monitor.

Razer seems to have drawn its design inspiration from the Casio G-Shock GB-6900 series. The Nabu Watch has a similar watch shape to that Casio model. There are four buttons - two on each side - with the command button in the middle, just like the GB-6900. The only differences are the wordings and button markings, which are in Razer's signature green.

Plus, the Nabu Watch is really big. It will probably only look small on the wrist of the wrestler movie star The Rock.

Its looks will likely endear it to Razer fans, although some might scorn its size and G-Shock looks. Personally, I think it looks cool, especially with the futuristic green time display on its main clock.

The main digital clock is said to have a battery life of one year with the use of a CR2302 cell battery. So you do not need to worry about losing the timekeeping function of the watch, unlike with smartwatches. You can use the Nabu app to sync the time, or you can adjust the time manually.

The battery that powers the small screen and smart features lasts for around one week before you need to recharge it using the proprietary USB cable.

But how frequently you need to recharge it will depend on how many notifications you receive.When alerts come in, the small screen will blink and show you the number of notifications. Press the command button to look at these alerts one by one.

In terms of steps tracking, the Nabu Watch is quite accurate, differing by only around 8 per cent from my calibrated Fitbit Charge HR.

But when it comes to sleep tracking, I found it to be inconsistent. There are times when it matched my Charge HR in terms of my light sleep data, and in keeping track of when I wake up. However, it sometimes registered a deep sleep status when I placed it on my table.

Razer claims the Nabu Watch is water resistant to a depth of 50m, as well as being shock resistant. I dropped the watch from 2m up on to a carpeted floor, and it continued to work fine.

• Verdict: Priced at $250, the Razer Nabu Watch is no more expensive than a G-Shock. However, it is a fitness tracker and displays notifications. Getting it depends on whether you are a Razer fan or not.
