Huawei Watch 3: Design

Four years is a long time and unsurprisingly the design of the new Watch 3 drastically differs from that of its predecessor. Gone are the thick bezels and the two-button layout. The Watch 3 steps proudly into the modern world equipped with a multifunctional rotating crown and a sleek 2.5D glass front.
There’s a pill-shaped button under the rotating crown, and this layout gives the Watch 3 a unique appearance. The strap connects to the body of the watch via a traditional two-horn hinge mechanism.
Huawei Watch 3: Display

The Watch 3 comes equipped with a 1.43-inch AMOLED display with a 466x466 resolution and a pixel density of 326PPI. This panel can produce up to 1000 nits of brightness, so outdoor visibility shouldn’t be a problem.
Huawei Watch 3: Hardware and connectivity
The Huawei Watch 3 runs on a custom-built LTE-enabled Hi6262 chipset and Harmony OS 2.0. There's 2GB of RAM on board, along with 16GB of native storage. The Watch 3 supports eSIM, LTE, Wi-Fi, and GPS. There are various sensors on board - a heart rate sensor, SpO2, and for the first time in Huawei wearable - a body temperature sensor.
Huawei Watch 3: Software and features

The Huawei Watch 3 is the first wearable equipped with Harmony OS - Huawei’s in-house developed operating system. The first big plus is the App Gallery, which is now on the watch itself. This means you can install apps without the need to transfer them via your smartphone.
There are other cool features baked in the watch - such as the ability to turn it into a remote control for your smartphone camera, unlock your car, or control your smart home appliances. The array of sensors provide quite thorough health tracking - you can monitor your body temperature, heart rate, SpO2, and sleep in real-time. The built-in fitness assistant supports more than 100 workout modes, and can also track your VO2max performance.
Huawei Watch 3: Battery life
Huawei smartwatches are notorious for their long battery life. The eSIM-support and the 60Hz display refresh rate have taken their toll, for sure, but the Watch 3 can still last 3 full days in 4G mode and up to 14 days in what the company calls ultra-long battery life mode.
The Huawei Watch 3 Pro on the other hand features a bigger battery and can stretch those numbers to 5 days of standard 4G use, and 21 days in ultra battery mode respectively.
Huawei Watch 3: Price and availability

The Huawei Watch 3 will be available in different styles - Active (silicone strap), Classic (leather strap), and Elite (metal strap). The Watch 3 Pro will be available in Classic and Elite Edition.
