As everyone's concept of physical health progresses, more and more people have begun to prevent diseases in advance. As a 24-hour wearable device, smart watches can monitor the body's data in a 24-hour and uninterrupted manner in real time with their size and portability, and understand the body's condition through more intuitive data.
And the end of the year is the best time to replace a smart watch, how can you choose a watch that suits you during this period? Next, we will start from three aspects: smart watch classification, smart watch brand, and appearance design, so that everyone can have a general understanding. Finally, we will also recommend three smart watches, which are also domestic products with the first echelon of comprehensive strength.
, smart watch classification
Currently, smart watches are mainly divided into two categories: , one is smart watch running RTOS system. Its advantage is that it has a long battery life and meets basic usage needs. The disadvantage is also quite obvious, that is, the scalability is not strong and third-party apps are extremely lacking.

The second category is smart watch running systems such as Hongmeng, WatchOS, ColorOS Watch, etc. Compared with RTOS, its battery life is naturally not as strong as RTOS, but the benefits are obvious. It not only has rich third-party APPs, but also can be used independently from the mobile phone.

2, smart watch brand
Currently, smart watch brands can be divided into two categories:
is a self-contained group, and is only compatible with its own devices:
Apple (WatchOS, only supports iOS ecosystem)
Huawei (only compatible with its own Hongmeng device)

has strong compatibility, and connecting to other devices does not affect normal use:
represents manufacturers: OPPO, Xiaomi

3, appearance design
appearance design is currently divided into two categories:
circular dial: the appearance is more in line with the traditional mechanical watch , which meets the aesthetics of most people, but the information reading rate is low
represents manufacturers: Samsung , Huawei, Xiaomi

(Huawei WATCH 3 Pro New)
Square dial: is more suitable for the design of smart watches. The square dial increases the available area of the screen, and the information reading rate is more complete
represents manufacturers: Apple, OPPO

adopts a bent upper and lower wrist growth design, which fits the wrist more well when worn, and the overall wearing feel is good. At the same time, an OLED screen with LTPO technology is provided on the front, which can achieve multi-stage adjustment of the refresh rate, and can also be displayed on the fly, which saves power consumption. This is also the only one among the current Android smartwatches. In terms of

function, it supports eSIM function, and can use the phone to make calls, surf the Internet, etc. The number of third-party APPs is also relatively rich. The app store has more than 80 applications, covering communication, payment, travel, entertainment, healthy and sports scenarios. Sports and health monitoring supports electrocardiogram detection function, cardiovascular assessment of the heart, all-weather heart rate monitoring, professional sleep monitoring, etc. It also has more than 100 exercise modes, and the experience is comprehensive and professional. With the support of Dual Engine Hybrid Technology 2.0, the battery life of the full smart mode can reach 5 days, and the light smart mode can reach 15 days, which is very durable.

Huawei Watch 3 Pro New
Recommended reasons: 21 days of ultra-long battery life, independent eSIM, support temperature monitoring,
Applicable people: Huawei Hongmeng device user
Huawei Watch 3 Pro New can be said to be the most worth buying watch for Hongmeng ecological users at present, and it is unique in terms of texture. sapphire glass mirror and a delicate and corrosion-resistant titanium shell, also use a ceramic back shell, paired with a brown leather strap or titanium strap, which has a very business-like texture. In terms of functionality, combined with the eSIM function and Hongmeng’s powerful multi-device interconnection experience, it can realize the smooth connection of mobile phones, tablets, headphones and other devices in all scenarios, and seamlessly control the whole-house smart products. In terms of sports, it supports more than 100 types of motion detection. Interestingly, it also has an independent ECG button design, body temperature measurement, all-weather continuous blood oxygen and other health monitoring functions, which always protects health. In terms of battery life, it can be used for 4 days in smart mode and for 21 days in ultra-long battery life, so there is no need to worry about battery power.

Xiaomi Watch S2
Recommended reasons: 12 days typical battery life, 1.47-inch super large circular screen, support temperature monitoring,
Applicable people: Xiaomi users, Android users, Apple users
In terms of texture, Xiaomi has also given good materials. The standard version uses a glass cover, while the leather version is equipped with a sapphire glass cover, which is scratch-resistant and wear-resistant in daily use, providing better protection performance. In terms of strap design, Xiaomi also gave a silicone strap version, and also provided the design of leather strap and contrasting strap, which corresponds to business occasions and fashion parties, to meet the needs of multiple scenes.

Xiaomi Watch S2 supports a very rich data detection, such as traditional routine testing projects such as heart rate, blood oxygen and pressure. In addition, it also adds body fat detection and skin temperature measurement to provide users with comprehensive and scientific data support in sports scenarios. The biggest highlight of Xiaomi Watch S2 is that it is equipped with a bioelectric impedance sensor. When detecting body fat data, it is supported by algorithms to finally obtain body composition data. It has a built-in 500mAh battery, which has a 12-day battery life, and its performance is enough for everyone to use on a daily basis.

Through the above-mentioned popular science, I believe that everyone has a preliminary understanding of smart watches, and the three smart watches recommended above all have strong strength. As the saying goes, no phone is finished. Every smart watch has such shortcomings. You can buy them according to your budget and needs. After all, the best thing that suits you is the one that suits you.
