Oppo Watch 2 vs Oppo Watch: what’s new and different?

Oppo Watch 2 is official as of a few days ago. The device comes packing the Snapdragon Wear 4100 chip along with a dual operating system.

Most of the details were leaked ahead of the big day so there were few real surprises. Oppo had also released a few teaser posters prior to the big day. One of these came with the wording “a shot at the ceiling of Android watches”. Is this really the case? Time will tell.

The Chinese-based outfit has made a name for itself in the smartphone space, and in recent years it is trying to do the same with wearables. This will be no mean task as competition is stiffer than ever.

Oppo Watch 2 is currently only available for purchase in its home country. No word yet on international availability but this will surely come in the months ahead.

The obvious questions are what has stayed the same, what’s new with the latest generation? Should you upgrade if you have the original? Let’s delve right into all of this.

Oppo Watch 2 vs Oppo Watch: Technical specs


As expected, Oppo Watch 2 comes in three different models. This includes two size variants, 46mm and 42mm, along with various colour choices. The 42mm is available in China with WiFi-only or eSIM, the 46mm only with eSIM. It remains unclear whether the global version will also have these eSIM options.

For comparison purposes, the original also came in three different variants. But these included a 46mm and 41mm. Also, you only have the eSIM and WiFi options for the 46mm – the 41mm is WiFi by default.

The look has not changed that much. So you still get something that broadly resembles the Apple Watch. Hence we get a square-shaped dial with rounded corners once again. There’s no crown, mind you. Instead you get two elongated buttons on the right and one of these has an LED indicator in the middle. All of this has been retained for Gen 2.

As far as the screen, there’s a 3D AMOLED on-board with a 60 Hz refresh rate, 326 PPI resolution and 100% DCI-P3 color gamut. The case is attached to a skin-friendly fluoroelastomer band with a traditional watch buckle.

The display of the 46mm is unchanged, so 1.91 inches in size. But the fact that the smaller model has increased in size allows for a larger screen this time around – a 1.75 inch instead of a 1.6 inch. This should make it easier to read your stats on the go.

Another slight boost to the smaller model is the fact that it is now rated 5 ATM for water resistance. The original 41mm has only a 3 ATM rating.

It’s clear that with Watch 2, Oppo has not really changed that much in terms of design. Only slight improvements on the first generation. But more exciting developments can be found under the hood.

Under the hood

Perhaps the biggest upgrade is that the new timepiece features the Snapdragon Wear 4100 processor and an Apollo 4s secondary chip. Oppo Watch 2 switches between the chipsets based on usage.

The original comes with the 3100 chip. Watches with the latest Qualcomm processor are few and far between. At least for now.

Mobvoi TicWatch 3 Pro is one of the handful that come with the latest tech. Having said that, we are expecting more devices to join this exclusive club in the near future. This includes the new Motorola watches which might land in the coming weeks.

The other important Oppo Watch 2 upgrade is a boost in native storage. This has now been doubled to 16GB.

GPS is there, as before, but in addition to GLONASS and BDS – GALILEO has been added to the list. The sensors are largely the same. Upgraded, of course, with new tech. The one fitness sensor addition is SpO2 on Oppo Watch 2.

As far as battery life, the dual-chip structure of Gen 2 conjures up to 4 day battery life. When running purely on RTOS, the timepiece can keep going for up to 16 days. The 46mm version packs a more sizeable Li-Ion 510mAh than the 430mAh of its predecessor. The 42mm has a smaller 360mAh.

Here’s a run-down of the similarities and differences in design and hardware.

Oppo Watch 2 vs Oppo Watch: Features

The Chinese version of Oppo Watch 2 runs on a ColourOS based on a combination of Android and RTOS. As before, the international version of the watch is expected to run on Wear OS. Most likely this will be the current version and not Wear OS 3.0 – but one can always hope.

Google has put a dampener on things with its blog post the other day. Apart from Samsung, we are now not expecting any Wear OS 3.0 watches until well into 2022.

Activity tracking

As mentioned, the one important activity tracking addition is the inclusion of an SpO2 sensor on Gen 2. This allows for monitoring your blood oxygen levels. A fall in value can be an indicator you are coming down with something –  a decline in levels can even be an indicator you have contracted COVID-19. During sleep a sharp fall in blood oxygen saturation can be an indicator of Sleep Apnea.

Oppo Watch 2 also gets better stress detection, a new Relax app and something called the Gaming Mode. All the other activity tracking features of the first generation have been ported over. And they are quite comprehensive. The original watch has received high marks from various review sites, and there’s no reason for this not to be the case with the new watch.

The satellite connectivity should also be slightly better now as the watch has the ability to tap into GALILEO. This can help fill gaps when GPS, GLONASS and BPS are struggling.

Smart functionality

Other non fitness features that can be found on Oppo Watch include cellular connectivity for making calls when you are away from your phone. Certain variants of the watch have eSim functionality which allow owners to use the same number as the SIM card on their phone. If you don’t need that, save a few bucks and go for the WiFi-only model.

Outside of that the watches offer local storage for music, an NFC chip for contactless payments, text and calendar alerts and more. The storage memory has been doubled for Oppo Watch 2 which means more space for your tunes.

Oppo Watch 2 vs Oppo Watch: Verdict

Oppo Watch 2 is an evolutionary upgrade on the first generation. If you’re in the market for a new watch it is clearly the one to go for over the first generation. If you already have the first generation, the boost in performance might be enough to prompt you to upgrade.

This comes in the form of the Qualcomm Snapdragon Wear 4100 chip and double the storage memory. Other improvements come thanks to the SpO2 sensor, better stress tracking, GLONASS and more.
