It has to be said that smart wearable devices are becoming more and more popular nowadays. When the functions of watches are becoming saturated, and when the basic functions of health and all-weather monitoring of sports are quite different, how can we make functional differences stand out? The “intelligence” of wearable devices has also become a new track for major manufacturers. OPPO recently released the new Watch 4 Pro. With its luxurious appearance, it is not just a good-looking “showcase”. It not only brings regular configuration upgrades but also further develops health and sports algorithms to become more professional.
The processor of OPPO Watch 4 Pro uses a wearable chip combination of Snapdragon W5 + Hengxuan 2700, which is also the basis for this watch to achieve UDDE dual-engine hybrid technology 3.0.
The small core chip Hengxuan 2700 has brought about a 34% performance improvement, and the running memory has also been upgraded to 2GB. It has been deeply optimized for more than 200 high-frequency user usage scenarios such as sleep monitoring, outdoor running, and message push. While providing a smoother experience, you can also take into account power saving.
It has also been upgraded with an 8-channel heart rate sensor, a 16-channel blood oxygen sensor, a wrist temperature sensor, and an ECG sensor, bringing more accurate and comprehensive sports health monitoring capabilities.
Also thanks to these sensors, it achieves coherent gesture control that is not found in other watch categories, and further enriches the use scenarios of the watch.
Next, let’s take a look at the performance of this OPPO Watch 4 Pro.
Design and Screen
In terms of appearance ce, the OPPO Watch 4 Pro integrates the style of the previous generation. The integrated stainless steel case is paired with an Italian cowhide strap in Dawn Brown color, which highlights the high-luxury texture and can meet the wearing needs of high-end people in various scenarios.
In addition, the plastic bracket has been removed from the screen, and there is a 0.1mm height difference between the metal case and the screen, which can enhance the sense of unity and visual thinness, and improve the anti-fall performance. 
In terms of wearing, it also conforms to the ergonomic design, which can maximize the curvature design of the screen and body, fit the wrist to the greatest extent, and bring the most comfortable wearing experience.
The watch body adopts a 1.91-inch LTPO full-curved flexiAMOLEDOLED screen with a resolution of 378×496 and PPI326 and supports intelligent adjustment of the screen refresh rate and global AOD dial display. The battery life is 15% longer than that of traditional AOLED, and it can also be lit continuously. Taking into account long battery life.
The material of the bottom cover at the bottom has also been upgraded from plastic to ceramic, which brings a high-end texture. In the middle part of the watch, multiple sensors such as heart rate and blood oxygen are integrated, and a new wrist temperature sensor is added.
It is worth mentioning that the heart rate sensor of the OPPO Watch 4 Pro has been upgraded to 8 channels, and the blood oxygen sensor has been upgraded to 16 channels. In theory, the detection capability is more accurate. Below are four metal magnetic charging contacts.
On the left side of the OPPO Watch 4 Pro watch body, the round one is the crown, which can be used for stand-alone, double-click, scroll, long p, press, and other operations; the oval-shaped one is the electrode, which cannot be pressed and is used to measure heart rate and blood pressure.
The crown also adds a mechanical diamond texture + CD pattern sandblasting and high-brightness process, bringing a texture that is no different from a mechanical watch. The left part is the speaker. The package also comes with a magnetic charger, USB Type-C charging cable, instructions, and other accessories. OPPO Watch 4 Pro supports VOOC flash charging and the official claims that charging can last a whole day in 10 minutes.
Health and Sports Functions
What I have to mention is the intuitive gesture control brought by OPPO Watch 4 Pro. You only need to make two fists to answer/hang up/mute calls, postpone alarms, open applications, switch songs, and other functions, making the most of these functions. The role of the sensor.
For example, when you make a call while driving, eating, or cooking, you no longer have to touch the screen hurriedly. You only need to make two fists to answer and hang up. It looks more stable and elegant. The crown can be raised when a call comes. It takes a certain amount of time to become familiar with the functions of muting and hanging up, but it will bring convenience once you are familiar with it.
Health monitoring
You can view daily activity information, sleep, heart rate, stress, and other information on the negative screen. This is also a standard feature of smartwatches. However, the OPPO Watch 4 Pro uses a more accurate 8-channel heart rate sensor, 16-channel blood oxygen sensor, and ECG monitoring functions to bring more accurate and comprehensive detection performance.
In terms of sleep, it supports full-scenario sleep monitoring, which can accurately record even naps and provide accurate sleep reports.
Includes trend analysis of sleep duration, sleep regularity, sleep scores, and snoring-related data. In addition, the OPPO Watch 4 Pro has an exclusive health smart eye, which integrates 5 self-developed algorithms. It can cross-analyze and remind abnormal signs from the fusion of multi-dimensional data such as HRV heart rate variability, blood oxygen, respiratory waveforms, and snoring monitored by the watch, comprehensively Wrist temperature changes (data needs to be recorded for 5 days) and heart rate trends, analyze body temperature changes, and provide recovery suggestions.
In addition, OPPO Watch 4 Pro has added a 60-second physical examination function, which can check four major risk assessments and seven major physical abnormality indicators. It does not require the cooperation of a mobile phone. You only need to raise your hand to measure the data monitored by the watch in the past. , to generate a simple and intuitive report.
The four major risks include heart health risk, blood vessel elasticity risk, body temperature risk, and sleep snoring risk. The seven major body abnormality indicators include vascular age, ECG, heart rate, blood oxygen saturation, pressure, wrist temperature, and sleep.
These data are more practical for users who are more concerned about health. For example, the ECG section provides an assessment of sinus rhythm. However, modern people generally have this problem, so the advice given is that no special examination is required. If there is, If you feel unwell, you still need to seek medical treatment in time.
Motion detection
In terms of sports, automatic sports recognition is also available, which can identify running, walking, rowing machines, swimming, and other sports. However, this is also a regular function of the watch. It also has satellite positioning, which can record movement trajectories during exercise.
OPPO Watch 4 Pro goes a step further and adds professional running posture recognition. It can directly monitor left and right foot balance, ground contact time, vertical amplitude, and other high-level running data without wearing other auxiliary equipment. This is also due to the upgrade of the sensor. It brings more accurate monitoring capabilities. Whether you are running outdoors or indoors, running posture data can be analyzed, allowing you to improve problems that arise during running.
OPPO Watch 4 Pro also brings an exclusive self-developed professional badminton mode, which records the most comprehensive 12 sports data in the industry. It can record the number of swings, forehand/backhand, overhand/underhand, and maximum racket speed, most frequently used Information such as continuous shooting and the active duration is quite professional.
Like professional running posture recognition, these data are very practical, allowing users to improve their weak points, thereby effectively improving their athletic ability. It is very practical and is equivalent to moving professional equipment into a watch.
Dial and NFC
In the watch face market, OPPO Watch 4 Pro has more than 400 watch faces to choose from, and all of them support personalized editing, support for changing component colors, background colors, and time styles. They are both beautiful and practical. Even if you want a business style, a casual style, or a sports style, you can find a style that satisfies you above. Different styles of dials, combined with different straps, make your outfit more versatile.
NFC
OPPO Watch 4 Pro supports full-featured NFC and can be used with OPPO’s “Huantai Health” APP to open bus cards and access cards. The most noteworthy thing is that OPPO Watch 4 Pro has added a sensorless car key, and has reached a system-level cooperation with Ideal for the first time. It can automatically open and close the lock when approaching the car door and supports all Ideal models.
However, since the product we tested is an engineering prototype, the APP in the screenshot has not yet added ideal support. Users can easily activate it after it is officially launched.
Moreover, OPPO Watch 4 Pro’s car key function supports not only ideal and ideal models, but also BYD, Changan, AIWAYS, Lantu, Honda, Te Nengxing, Leapmoon, Nine Electric, Mavericks Electric, Yadi Electric, etc. The brand will be connected to successive car companies in the future.
Third-party software
In terms of third-party applications, OPPO Watch 4 Pro continues to expand its application ecosystem, covering a variety of social, news, payment, and music APPs, all of which are very practical, including national-level APPs such as QQ, WeChat, and Alipay. , adapted to a total of 85+ APPs, covering multiple usage scenarios.
OPPO Watch 4 Pro supports WLAN. Even if you don’t want to rely on your mobile phone, you can open the “Software Store” after the watch is connected to the Internet and the installation can be completed on the watch.
Verdict
On the basis of the original high-quality screen and dual-core support, OPPO Watch 4 Pro has further continuously optimized the algorithm to bring a more professional and better user experience.
The author feels that the most impressive feature of the use experience is the 60-second physical check-up function. On ordinary watches, information such as blood oxygen, heart rate, and sleep are displayed separately. There is still a certain threshold for understanding one’s physical condition.
But with this 60-second physical examination, it can cross-analyze past monitoring data through the unique Health Eye data. It can give you an intuitive and clear report anytime, anywhere, in just 60 seconds with just a lift of your wrist, which is quite convenient. For users who pay more attention to health, this function allows you to take precautions in advance and maintain good health at all times.
There is also professional running posture recognition and professional badminton mode, which can generate your own sports report. This is the icing on the cake for users who love sports. It can be said that professional equipment has been moved into the watch. The weak points can be clearly seen at a glance, so that you can target them. Sexual improvements will take your athletic ability to the next level.
From an experience point of view, OPPO Watch 4 Pro is not just a derivative of a mobile phone, but a device that can independently bring a “smart experience” to users, and it further extends to cars.
In particular, the car key feature is very practical. For car owners who often forget to pick up their mobile phones or their mobile phones are out of battery, they can unlock the car door with just a lift of their wrist. This experience is indeed very comfortable.
It also maintains excellent battery life as always. The author personally tested that when the blood oxygen, heart rate, and sleep functions are fully turned on, it can achieve 4 to 5 days of battery life in full smart mode, which is no different from the official promotion; in light mode It can achieve up to two weeks of battery life, and there is no battery life anxiety.
Overall, I feel that this OPPO Watch 4 Pro has no shortcomings in terms of experience. In addition, it takes the high-luxury quality route. It only costs 2,299 yuan to obtain such a great appearance and strength. The coexistence of high-end watches is well worth your consideration.
