OnePlus Classic Smartwatch Review

OnePlus Classic Smartwatch Review

OnePlus, a name synonymous with excellent smartphones is trying to conquer the smartwatch sector with its OnePlus watch. As with their smartphones, OnePlus has attempted to pack this watch full of flagship features whilst not exceeding the affordable price range, which to be honest is expected from them. But does it fulfill our expectations? Let’s find out in this review.

Build and Design

The OnePlus Classic Smartwatch looks elegant and sleek with a classic round dial look. The first thing that comes to everyone’s mind when they are asked to imagine a smartwatch will most probably be a square-looking one. OnePlus has broken this tradition with a 46mm round dial design with stylish thin bezels and just two buttons on the right side. One even has the OnePlus logo etched on it. Each button’s dedicated purposes are to access the menu and workout modes respectively.

The display is a brilliant 1.39 inch AMOLED with enough brightness to be visible during daylight. It has a 2.5D curved glass sitting on top of it just like a tempered glass protector on a smartphone screen. The watch body is made out of 316L stainless steel which makes it quite rigid and sturdy. The backside however is covered with plastic with microphone holes, speakers, and charging pads on it. The straps are made of high-quality fluoroelastomer and standard 22mm in size with quick connect and disconnect latches like in Apple watches.

OnePlus Smartwatch is packed with tons of sensors and is equipped with a 402mAh battery. It weighs about 45 grams without the straps and 76 grams with them attached, which is a bit heavy on the hand.

Performance and features

The OnePlus watch runs on RTOS (Real-Time Operating System) as supposed to Google’s wear OS. Hence there is no smart assistant support of any kind. But this doesn’t mean the watch is not feature-rich. It has its own watch OS with a simple yet elegant UI and a wide range of watch faces you can select from. With Bluetooth 5.0 at its heart, you can pair the watch with any smartphone running Android 6.0 and above. Yes, you read that right! OnePlus watch can only connect with android phones. So this drastically reduces its market among iPhone users.

As mentioned before the OnePlus watch comes with an Acceleration sensor Gyroscope sensor, Geomagnetic sensor, Optical heart rate and blood oxygen sensor, Ambient light sensor, Air pressure sensor, and a Capacitance sensor. It also has IP68 water resistance with a 5ATM rating and 4GB of built-in storage for listening to offline songs.

Health tracking seems to be the selling point of this watch as it uses its various sensors combined with the OnePlus Health app for monitoring steps, heart rate, daily calorie burn, blood oxygen level, and even sleep.

OnePlus watch is advertised to last as much as 12 to 14 days of typical use with a single charge. If sleep blood oxygen monitoring is used then that number comes down to 5 days and if continuous workout tracking with GPS is enabled then it only lasts 25 hours.

Limited Editions

OnePlus smartwatch has a Cobalt limited edition aside from the classic one. The differences are the Cobalt edition watch as the name suggests has its body made of a cobalt alloy that is twice as durable and corrosion-resistant as the classic stainless steel version. It also comes with a Vegan leather strap with a butterfly buckle and a sapphire crystal display. Succeeding it is the OnePlus Watch Harry Potter Limited Edition which you can guess by the name is filled with the harry potter theme. Everything from Harry’s scar etched on a button to embossed Hogwarts crest on either side of the rich brown leather strap makes this edition a must-have for every potter fan.


The OnePlus watch is available in Midnight Black and Moonlight Silver to buy from amazon and the OnePlus website at a price of 14,999. ~ $ 200 ( price in India )

Amazfit GTR 2e – Priced significantly lower than the OnePlus watch, Amazfit GTR 2e is perfect for you if tracking fitness and health monitoring is your primary goal.

Samsung Galaxy Watch Active 2 – Priced at an almost similar range this watch offers certain features and hardware that the OnePlus watch cannot. Equipped with Tizen OS, high-end hardware, and robust software Samsung Galaxy Watch Active 2 is definitely a worthy alternative to consider.
