The Huawei Watch Fit 4 series has arrived, and for the first time, the lineup includes a Pro version. The standard variant offers a minor update over its predecessor, but the Pro takes a big step forward, further blurring the lines between smartwatches and smartbands. After spending a few weeks with it, here's what we found out. Table of Contents: Design

Verdict Design
The Fit 4 Pro is the thinnest Fit to date, measuring just 9.3 mm, and features the Huawei TruSense System sensors, introduced at a special event last summer. The watch itself is extremely light and yet thanks to its titanium alloy bezel, sapphire glass screen, and aluminum body.
The Green version comes with a matching nylon woven strap, but you can get additional straps - like the ones from the Black and Blue versions. These straps are made from fluoroelastomer and come with a traditional clasp.
The first thing that caught our attention is the screen – the Watch Fit 4 Pro is built around a 1.82" AMOLED display that is incredibly bright, with excellent legibility even in direct sunlight. Huawei claims an impressive peak brightness of 3,000 nits, matching the far more premium Watch 5 wearable.
We cannot overlook the similarities to an Apple Watch, but Huawei says the design and aesthetics are what consumers desire, and the company is merely responding to its users' preferences.
At least the crown button has a green color that looks great with the official band but appears somewhat out of place with a different strap. The bottom key is a quick access button, but it also serves as an ECG sensor – a feature available only on the Pro. Display
Huawei claims the panel features an "ultra-high retina resolution of 347 ppi." The display is impressively vibrant and tack sharp. Additionally, the interface is well optimized for the shape, meaning both looks and usability are great.
The bright panel serves well as a flashlight and its size makes thing easily readable even when you are in the zone and your vision is blurry from excessive effort.
HarmonyOS categorizes watch faces into three groups based on power consumption. Most of them also support AOD, which works well enough – it is visually appealing and easy on the eyes.
The Raise to Wake gesture also works as expected – detects motion, understands what needs to be done, and turns the display on and off as needed. Software & Hardware
The TruSense System integrates hardware sensors located on the back of the watch, operating in harmony (pun intended) with the operating system.
The Watch Fit 4 Pro includes six sensors that measure respiratory rate, SpO2 (blood oxygen levels), body temperature, blood pressure, and heart rate. In theory, these sensors offer 98% accuracy with under 2% error in readings, compared with certified medical equipment.
Still, the Watch Fit 4 Pro is still a mid-range wearable, which is why Huawei excluded the Health Glance feature that was heavily promoted in the Watch GT 5 and Watch 5 series. However, the Watch Fit 4 Pro still offers comprehensive health tracking, accessible through the Huawei Health app.
A few years back, Huawei obtained ECG health certifications, enabling the Fit 4 Pro to collect heart rhythm data.
Functions that debuted in GT 5 Pro and subsequently appeared in Watch GT 4 are now being integrated into the Fit line. One notable addition is the enhanced functionality for trail running.
This wearable enables runners to upload GPX tracks and navigate using a colored contour map, an offline toned-down version of Petal Maps.
In relation to Petal Maps, the Fit 4 Pro provides step-by-step navigation, though this feature activates only when the directions are configured through the phone app. Battery life
The Fit 4 Pro has a 400 mAh battery inside, just like the Fit 4. Yet the Pro charges from 0 to 100% quicker, only 60 minutes with the provided magnetic wireless charger. The design of the TruSense System allowed for a better architecture of the charging module, thus filling up the cell quicker.
We must point out that any Qi charger would work to charge the device, but it won't be as quick as the CW05 puck provided in the box.
We tested the battery life in multiple scenarios: with and without notifications, between 30 and 240 minutes of exercise every other day, variable display brightness, and GPS navigation while running.
Huawei promises 7 days of battery life with an active lifestyle; however, we struggled to achieve this in any scenario. The best case was six days, but this included no notifications and only 60 minutes of activity tracking during that period.
Using the Always-On Display reduces battery life by approximately 30%. The six-day routine provided us with four days, whereas the 10-day scenario with no running and notifications was nearly seven days with AOD on. Verdict
Huawei Fit 4 Pro starts at £250, but the Green version is priced slightly higher, due to its more premium band. The company frequently offers its devices bundled with services and accessories (where available), enhancing the overall value of the deal.
Huawei made significant progress in bridging the gap between the GT series, and the Fit lineup, effectively delivering the same functionality in two different designs and at two different price points.
The Watch Fit 4 Pro is an excellent option for those who are health-conscious, active in sports, and desire a wearable that appears minimalistic yet still has character.
