Just Corseca Ray K’anabis Smartwatch Review

The Just Corseca Ray K’anabis relies on IP68 Water-resistant, advanced HR sensor, and robust housing. In this review, we evaluate whether this is enough for the hard-fought middle class of smartwatches.

Many of us wouldn’t be much familiar with a brand called “Just Corseca”. However, this well-established accessories manufacturer is slowly but significantly started grabbing Indian consumers’ attention due to its quality products and reasonable prices. Out of its wide range of products, one is Just Corseca Ray K’anabis Smartwatch”. Which is a perfect alternative to Amazfit T-Rex looks because of its similar chunky and robust looks and features.

We tried Ray K’anabis for more than one month and after that here are our thoughts about whether one should buy it or not.

Design, Specification, and Operations

The Just Corseca Ray K’anabis is in a bulky plastic housing. The bezel, i.e. the edge around the display, is reminiscent of Casio’s G-Shock design. Due to the protruding shape, the bezel protects the display. Coming with Water Resistant (IP68) feature – the watch can resist liquid splashes and sweat during a workout, however, users can’t wear it underwater. With UV reflector coating it is easy to read and watch even in the bright sunlight when the maximum brightness is set. To activate the display-  raise your arm or press one of the two buttons, the watch doesn’t respond to tapping on the screen.

Just Corseca Ray K’anabis Fitness functions

Smartwatch has been equipped with plenty of sensors for recording training sessions and displaying general health measurements. In our test, the heart rate was almost correct even when the arms moved a lot. In sports mode- the watch is armed with options to measure your training sessions such as walking, running, cycling, skipping, badminton, basketball, and Football. However, even though the company bosted the watch has an IP68 rating still there is no swimming training mode. In the practical test, for example, the watch recognized a walk after just two minutes and also noticed when it was over. The watch automatically detects sleep and recorded sleep duration, however, its accuracy is not up to the mark and tended to add a few extra hours.

A user cannot rely on the sensors of smartwatches to diagnose some health issues however, he or she can have some idea. Pedometer, Heart Rate Monitor, SpO2 (Blood Oxygen) Monitor, Blood Pressure Monitor, Calorie Count, and Step Count are some other monitoring features but the user should not rely on a single result. I mean if you are trying to monitor your heart rate then measure it at least 5 times to get an average value to rely on. Otherwise, all sensors work perfectly in our test.

In connection with the smartphone, the Just Corseca Ray K’anabis provides a few clever functions. It mirrors weather information and vibrates notifications, and also offers a call answer function. A (vibration) alarm clock can be set.

The best thing is we can use the smartwatch to directly access phone contacts (favorite contacts added via app) or dial manually the number to call. In short, we can use the watch to call and talk without touching the smartphone; thanks to the inbuilt speaker and mic. However, the watch and smartphone must be connected via Bluetooth.

Unfortunately, there is no calendar function. The watch can controls the music playback on the smartphone remotely. All the functions offered worked in the practical test. The system cannot be expanded with apps.

Furthermore, we can click photos using the watch’s “Shutter” option; Alarm, Stopwatch, and Countdown are a few other useful options during training sessions.

Da Fit app

By default, there will 5 watch faces on our Just Corseca Ray K’anabis, out of one can be changed manually as per choice. However, to change the Watch face, we have to take the help of an app called the Da Fit app. It is available for both Android and iOS phones.

To connect the smartwatch to Da fit app, first, download it from your iOS or google play store. Once the installation is completed, turn on your smartphone’s Bluetooth, and add a new device there you will find a device named “K’anabis” and select to connect the same.

Once connected, open the Da fit app, under different watch models select K’anabis. To change the Watch faces, select the options given for it. Scroll down to More faces and select the one you want to set for your smartwatch.

Just Corseca Ray K’anabis Battery

The battery of the Just Corseca Ray K’anabis is 400 mAh better than the Amazfit T-Rex Pro. In our practical test, the watch lasted for 11 days with all functions activated and heart rate measurement. However, if we don’t connect the watch with a smartphone then we can easily go for more than 20 days. In short, the smartwatch has an impressive battery backup. Furthermore, when it comes to charging then a user can have a full charge in around 1.5 hours.

Charging Corseca Smartwatch



We are quite impressed by the Just Corseca Ray K’anabis. The watch is priced in the lower segment for smart sports watches, but overall it delivers a lot of features. The smartwatch is available for INR 8,998. The long battery life, the various training options, and analyses, as well as the helpful hints for sleep recording, coupled with the robust workmanship, form an overall package for which we can give an almost unreserved purchase recommendation. If you can do without additional functions such as a payment option and your music storage, you will be perfectly happy with the Just Corseca Ray K’anabis…
