Oppo Watch ECG first watch under Wear Os with electrocardiogram

Price: 252 € (current model) – from € 249 (with ECG) | Oppo (China, founded in 2004)

If the market for smartwatches for health monitoring with ECG is booming, watches under the Wear Os operating system were absent. So since the start of the 2020 school year, we have seen the arrival of new models with ECG coming out:

The Chinese giant has just announced the release of the first smartwatch under Wear Os with ECG sensor. It’s funny to note that it was only a few days after the announcement of the Apple Watch 6 which also added the ECG, that Oppo reacted with this update.

Oppo Watch ECG Design

The new version continues the styling of the original model which has the very familiar look and feel of the Apple Watch. Note a nice different aesthetic in favor of the Oppo Watch which is its curved screen.

On the other hand, the Chinese always uses these 2 buttons on the right for navigation in addition to the touch screen, instead of the elegant crown of Apple. The bottom button has a subtle green accent to add character. By default, it launches the fitness suite, but its function can also be customized. We miss the crowns and rotating bezels that some of its competitors offer, but the otherwise fast interface makes up for that.

The left side houses the speaker.

The watch is offered in two case sizes 41 and 46 mm. The frame is in aluminum alloy, although only the 46 mm model is equipped with a bottom plate in ceramic.

  • 41 or 46 mm aluminum case
  • Water resistant 5 ATM

Cocorico the eSIM is made in Thales

The eSIM embedded in the Oppo Watch, the brand’s top-of-the-range, is produced by the French company Thales. The chip has been approved by the three Chinese mobile operators, so it should be the same for French operators by October 24, 2020.

Curved rectangular screen

It is available in two sizes. There is a 41 mm model which includes an é1.6 inch AMOLED display square with a resolution of 320 × 360 pixels at 301ppi.

For those who want the “real” Wear Os experience with the new Oppo watch, the 46 mm model could be more attractive. Indeed he adds the LTE connectivity (e-eSIM), and a large 1.9 inch 402 × 476 pixel AMOLED display at 326 ppi with superb maximum brightness of 1000 nits.

Personalization of the screen and wristband

It is possible to choose the color of its frame according to the model:

  • Oppo 41 mm case in black, pink or gold (30 grams)
  • Oppo 46 mm in black or gold (Wifi version or optional eSIM card, approx. 41 g)

For personalization, you can take advantage of removable straps with leather, silicone or rubber options.

Finally, you get the faces built into the Oppo system, as well as the large library offered by Wear Os.

Features Oppo Watch ECG

Oppo’s Wear Os smartwatch uses Qualcomm’s Snapdragon Wear 3100 chipset, but it also has an Ambiq Micro Apollo3 coprocessor that allows it to increase its lifespan and longevity.

  • Snapdragon Wear 3100 and Ambiq Micro Apollo3
  • Wear OS
  • 1 GB RAM and 8 GB ROM
  • Integrated GPS (A-GPS and GLONASS)
  • Waterproof 5 ATM
  • Speaker / microphone (phone call, Google Assistant)
  • NFC contactless payment chip
  • 2.4 G WiFi and Bluetooth 4.2.
  • ECG, pulse, ambient light, barometer, 3-axis accelerometer and gyroscope sensors

The Snapdragon Wear 3100 platform launched two years ago has received a useful redesign in the form of the Snapdragon Wear 4100 this year. But for now Oppo is keeping the 3100 chip.

The smartwatch only ships with one memory configuration. It thus embeds 1 GB of RAM and 8 GB of internal storage available, regardless of the model chosen. This combination makes the Extremely smooth and responsive operations, which is again a rare feat for Wear Os watches.

This is because it wakes up quickly from sleep mode, reacts quickly to tapping and sliding, and doesn’t spend too much time charging.

Smartphone functions

The Oppo Watch offers some of the best features we’ve seen from a watch using Google’s software. Its formatting functions are suitable for everyone, the power is enough to run all the apps you need and there are also a few extras added by Oppo.

  • Display of notifications (SMS, social networks, messages)
  • Taking phone calls on the wrist
  • Google Assistant voice commands
  • Race list, reminders, appointments
  • Stopwatch and countdown
  • Controlling music on the watch screen
  • Google Fit activity tracking
  • Google Pay contactless payment
  • Ring your phone to find it (or vice versa)

Smooth and fast navigation

The notification shade on top, which borrows the color scheme and iconography of Oppo’s namesake for smartphones, and the app drawer are perfectly done.

The quick buttons at the top include all the essentials like sound profiles, theater mode, lock, flashlight mode, “Find my phone” function and brightness control. The use and really intuitive thanks to the universal icons.

Health functions

  • Integrated heart rate monitoring
  • ECG sensor
  • Guided breathing
  • Sleep tracking

First of all, it is equipped with a heart rate monitoring which regularly checks your pulse and follows it. It can also alert you to any unusual or high readings.

The update adds the ECG sensor which allows you to get a electrocardiogram on demand. The Oppo Watch ECG watch has been certified as a class II medical device by the Chinese Food and Drug Administration. Thus, Oppo has become the second Chinese brand offering a certified ECG watch.

Better, Oppo claims that the Watch ECG edition has already obtained FDA approval in the United States.

By mixing ECG and heart rate, it can not only understand the health of your heart, but also predict heart disease and risk. You can see the speed of your heartbeat and the dynamics of your heartbeat in real time. In the event of an abnormal heart rhythm, you will immediately receive an alert.

Finally, it only lacks an SpO2 sensor to measure the level of oxygen in the blood to bring it up to the level of the Apple Watch Series 6.

Function followed by activity

  • Google Fit offers over 90 tracking modes
  • HeyTap Health Suite Offers More Exercises
  • Integrated gps

The GPS is integrated to follow your races or your hikes, ski or bike.

The inactivated alert is also present, and even offers to make you do a fairly long stretching session every hour.

Traditionally, we find Google Fit p with hundreds of exercise and sports tracking options. This includes a number of water sports like stand-up paddle boarding and kite surfing. However, it is strongly recommended not to use the Oppo Watch ECG in seawater.

The HeyTap Health app in addition to Google Fit

If that wasn’t enough, the Oppo Watch gives you the option to download the HeyTap Health app. Contrary to what the name suggests, it acts as a hub for many of the watch’s features.

It offers five specially designed training programs: Fitness Running, Fat Burning Running, Outdoor Walking, Outdoor Cycling, and Swimming. By selecting them, you will be guided through a series of instructions as well as the target heart rate.

These additions make the Oppo Watch ECG a very practical training companion.

It has something to offer users of all skill levels. All of the exercises, heart rate monitoring, and pedometer seem to work with reasonable accuracy.

Parental control option (in China)

Not long ago, OPPO and Xiaotiancai Watch started a partnership, and the social network app “WeChat” was added to the OPPO Watch app store. This allowed OPPO to have the “first” watch using this famous Xiaotiancai social network. With this app, parents can join Xiaotiancai family group through OPPO Watch, send voice messages with children who use Xiaotiancai watch and receive voice, text and emoticon messages.

Oppo ECG watch autonomy

On the battery version it measures 300mAh, which should last around 24 hours of “normal” use, but can be extended up to 14 days when the power saving mode is activated.

The battery is also slightly larger, at 430mAh, and should last 30 hours in “smart mode” or up to 21 days in power saving mode.

One of the main advantages of both smartwatches is their compatibility with SuperVOOC flash charging technology. This allows them to fully recharge in just 75 minutes from 0%. To do this, simply place the watch on its included fast charging unit.

Oppo Watch ECG price and release date

The officialization of the Oppo with ECG was made on September 24, 2020 in China. But, it remains to be seen if we’ll see an international version eventually. As it took almost 4 months for the first version to come out of Chinese borders, we could have it in France by the end of 2020.

The official prices and release date of the Oppo Watch ECG international version:

  • Black or pink 41 mm model at € 249, October 2, 2020.
  • The 46 mm black version starts at 2,499 Yuan, or 329 euros for us, on October 2, 2020.
  • The Oppo Watch with eSIM only at 46mm should be released on October 22, 2020 at the price of 349 euros. An excellent price, corresponding to a similar configuration at half the price of the watch with an apple.

In the meantime, the ECG version, the lookalike of the Apple Watch for Android is already available at € 252 on Amazon.

Oppo Watch ECG review

The Oppo watch is one of the best Wear OS smartwatches you can buy in the Apple Watch style. It upgrades to the new Apple 6 series by adding the ECG sensor.

Without innovating in the general design, there are many appreciable details such as its display quality and the fluidity of navigation.

Just beware of its battery life, a weakness common to watches running Wear OS 3100.


  • An elegant design and beautiful finishes
  • A very nice bright display
  • Works well and quickly


  • Autonomy
  • Lack of originality
