Huawei Watch Fit 4 Pro

If the regular Fit 4 is a featherweight daily companion, the Huawei Watch Fit 4 Pro is the version for people who intend to push a rectangular watch outdoors. It keeps the thin 9.3 mm profile and the 1.82-inch AMOLED panel of the Fit family, but swaps in a sapphire cover glass, a titanium bezel, an ECG sensor, a depth sensor, a free-diving certification and a golf course database. This page is a specification-and-information review based on the published specifications and manufacturer information. Brightness, battery and charging numbers are Huawei laboratory figures, not independent measurements, and several of the headline features depend on region or on the phone you pair it with.

What the Pro label actually changes

Reading the official specification sheets side by side shows the Pro is not just a recoloured Fit 4. The case grows to 44.5 x 40.0 x 9.3 mm and the weight to about 30.4 g without a strap, roughly three grams heavier than the standard model, yet it is also thinner. The panel is the same size and resolution, 480 x 408 pixels at 347 ppi, but Huawei quotes a 3,000-nit peak against 2,000 nits for the base watch. The sensor list gains ECG, temperature and depth. On the positioning side both watches share the same dual-band satellite support, so the Pro does not navigate better in satellite terms, but it adds route and map tools aimed at golf, mountaineering and water sports. If you came here from the other Fit 4 review, think of the Pro as a differently equipped watch rather than a mere upgrade of the same one. A short route through the lineup is to place it next to the Huawei Watch Fit 5 Pro, its successor, and the round Huawei Watch GT 7.

Materials and build

Huawei describes a three-part defence against scratches and knocks: a mid-frame of aluminum alloy that it calls ultra-strong, a bezel in titanium alloy for corrosion resistance, and a screen covered by artificial sapphire glass. Sapphire is considerably harder than the glass normally used on fitness bands, so the display should tolerate keys, door frames and rock better, which is the most tangible reason to choose this model. The case keeps the rotating crown and side button and adds the electrode used for the ECG measurement on the side. The distinctive 3D wing-like shape of the case and strap lugs is shared with the standard model, but the Pro comes in only three colourways: green with a woven nylon strap, and blue or black with fluoroelastomer. Wrist size is given as 130-210 mm for all of them. NFC is supported on the Pro without the variant restriction mentioned for the standard watch.

Display

The AMOLED screen is the same 1.82 inches, but the higher 3,000-nit peak, the sapphire cover and the dark watch faces in Huawei's press images are aimed at readability on a golf course or a ski slope in bright light. Peak brightness is only reached in short bursts under specific content, so day-to-day brightness will be lower, though the headroom is welcome outdoors. Huawei describes the always-on display as optional, with battery figures changing accordingly.

Outdoor and sports tools

This is where the Pro earns its name. Golf is the headline: Huawei advertises a database of more than 15,000 golf courses with 3D fairway views, green and bunker information, distance measurements from any point you tap on the map, a digital scorecard with handicap, fairway-hit and green percentages, swing analysis and post-round review. The footnotes note that course maps for the Chinese mainland require a Huawei Health account registered there, and that maps are downloaded through the app, so check coverage for your region before treating golf as a selling point.

For hikers and trail runners the barometer, the satellite system and the map views support segment-based navigation and trail information such as remaining distance, ascent to a marked location and estimated completion time. Voice alerts, vibration and on-screen arrows tell you when you have strayed from a loaded track. Huawei lists mountaineering, hiking, skiing and triathlon among the modes that use the improved altitude measurement.

Water use is the other differentiator. The watch carries 5 ATM water resistance, an IP6X dust rating and an EN 13319 certification that Huawei says covers free dives to 40 metres. A built-in depth sensor tracks dives, and the freedive mode adds features such as a hover timer, water-type identification and breath-hold tracking with breathing guidance. Huawei also lists apnea training and testing, together with a strong safety warning that such training should be done on land, in a lying or sitting position, under supervision. The manufacturer excludes scuba, technical diving and anything beyond 40 m, along with hot showers and saunas. Water workouts include surfing, sailing, rafting, boating and kayaking with trajectory recording. Nylon straps are not meant for water use, so the blue or black fluoroelastomer versions are the sensible choice for swimmers and divers.

Health tracking and the ECG app

The extra sensors give the Pro a more complete health story than the base model. The ECG app asks you to touch the side electrode for about 30 seconds and then reports a sinus rhythm result or a reminder of atrial fibrillation or other irregularities; availability depends on country. Huawei states that the electrode technology has been improved for faster and more accurate signal collection. Beyond ECG, the Pro offers the PPG-based alerts for possible atrial fibrillation and premature beats, sleep monitoring with abnormal-breathing alerts, stress tracking, SpO2, menstrual cycle tracking and the Emotional Wellbeing and Health Insights apps. As with every watch of this kind, the readings are for reference only, the product is not a medical device, and it is not intended for diagnosis.

Battery and charging

The claimed battery life matches the standard model: up to 10 days at maximum, about 7 days of typical use and up to 4 days with always-on display, all from Huawei lab tests with a specified usage profile. What differs is the charging time, which Huawei puts at about 60 minutes to full on the second-generation wireless charger supplied in the box, against 75 minutes for the standard watch. A ten-minute charge is said to cover a day of typical use. Because outdoor modes with GPS, map views and the always-on screen all use more power than the test profile, serious users should expect fewer days than the headline figure.

Who should buy it

The Pro makes sense for golfers, hikers, swimmers and freedivers who prefer a light rectangular watch over a heavy sports watch, and for people who want an on-wrist ECG and a scratch-resistant screen for daily wear. It works with Android 8.0 or later and iOS 13.0 or later through the Huawei Health app. If you only walk, run casually and read notifications, the lighter and simpler Fit 4 will cover the basics; our comparison with the standard Fit 4 shows the differences.

Limitations

• Golf course coverage and some health features, including ECG, depend on country and account region.
• It is slightly heavier and larger than the base model, and the sapphire and titanium do not make it a dedicated expedition watch.
• The EN 13319 rating covers free dives to 40 m only; scuba and deeper diving are excluded.
• There is no cellular radio and no on-watch music storage listed in the specifications.
• Battery figures drop quickly when GPS, maps and always-on display are in constant use.

In short, the Watch Fit 4 Pro is a light rectangular watch with unusually serious outdoor and health hardware for its size. Compare it with other wearables in our rankings.
