Huawei Watch GT 2 Pro Specs Leaked? Full Breakdown

Yes, the Huawei Watch GT 2 Pro specifications were leaked extensively in 2020 before its official release, and the leaks proved to be largely accurate. The watch was officially announced in September 2020, and the leaked specs matched the final product almost exactly, including the titanium case, sapphire glass display, and the new SpO2 and heart rate tracking features. This article compiles the confirmed specifications, the history of the leaks, and what they meant for buyers at the time.

Background: The Leak Timeline

The first credible leaks of the Huawei Watch GT 2 Pro appeared in early August 2020, about six weeks before the official launch. The leaks came from a combination of regulatory filings (such as Bluetooth SIG and FCC listings) and tipsters who shared renders and spec sheets. The most notable leak was a series of press renders and a detailed spec list shared by a well-known leaker on social media, which matched almost exactly what Huawei later announced. The official launch took place on September 10, 2020, alongside the Huawei Mate 40 series (though the phone was delayed to October). The leaks were so accurate that many tech journalists used them as the basis for pre-launch coverage, and the final product confirmed nearly every detail, including the 5ATM water resistance and the 14-day battery life claim.

Confirmed Specifications from Leaks and Official Sources

The leaked specifications that turned out to be accurate include:

• Display: 1.39-inch AMOLED, 454 x 454 pixels, 326 PPI, sapphire glass cover
• Case materials: Titanium alloy case, ceramic back, sapphire glass lens on the sensor
• Dimensions: 46.7 x 46.7 x 11.4 mm (without sensor bump)
• Weight: About 52 grams (without strap)
• Processor: Huawei Kirin A1 chip
• Memory: 4GB internal storage (for music), no mention of RAM in official specs
• Battery: 455 mAh, up to 14 days typical usage, 7 days with heavy use
• Charging: Wireless charging (Qi-compatible) and reverse wireless charging from a phone
• Sensors: Accelerometer, gyroscope, barometer, optical heart rate sensor, SpO2 sensor, GPS (dual-band: L1+L5), GLONASS, Galileo, BeiDou
• Water resistance: 5ATM (up to 50 meters)
• Connectivity: Bluetooth 5.1, NFC (for payments in some regions), no Wi-Fi, no LTE
• Operating system: HarmonyOS 2.0 (later updated from LiteOS on the original GT series)

How the Leaks Compared to the Final Product

The leaks were almost perfect. The only minor discrepancies were in the exact weight (leaks said 52g, official was 52.5g) and the battery capacity (leaks said 455 mAh, official was the same). The design renders also matched the final product, including the two-button layout on the right side and the ceramic bezel around the sensor. The leak of the SpO2 sensor was particularly notable because it was a new feature for the GT series, and it was accurately predicted. The only thing that was not leaked in detail was the exact pricing and availability in different markets, which varied by region.

Key Features That the Leaks Revealed

The leaks highlighted several features that made the GT 2 Pro stand out:

• Premium materials: The titanium case and sapphire glass were a significant upgrade from the aluminum and regular glass on the GT 2.
• Wireless charging: This was the first Huawei smartwatch to support wireless charging, and the leaks correctly showed a magnetic charging puck.
• SpO2 monitoring: The blood oxygen sensor was new, and the leaks indicated it would be used for altitude acclimation and sleep tracking.
• Dual-band GPS: The inclusion of L1+L5 GPS was a major improvement for accuracy in urban canyons and tree cover.
• 100+ workout modes: The leaks mentioned a wide range of exercise tracking, including golf and skiing.

Common Problems and Limitations

Despite the accurate leaks, the GT 2 Pro had some limitations that were not fully highlighted in the pre-release rumors:

• No third-party apps: The watch runs HarmonyOS, but it does not support a broad app ecosystem like Wear OS. You cannot install WhatsApp or Spotify directly on the watch.
• iOS compatibility is limited: While the watch works with iPhones, some features like answering calls from the watch and sending quick replies are not available.
• No built-in speaker for music: You can store music on the watch, but you need Bluetooth headphones to listen; there is no speaker.
• Charging requires a specific puck: Although it is Qi-compatible, the charging contacts on the back mean that not all Qi chargers will work; the official puck is recommended.

How to Choose Between GT 2 Pro and Other Huawei Watches

If you are considering a Huawei smartwatch today, the GT 2 Pro is still a solid option, but you should compare it with the newer GT 3 Pro and the Watch GT Runner. Here is a quick guide:

• GT 2 Pro: Best for those who want a premium build (titanium, sapphire) and are okay with an older processor and no speaker. Often cheaper than newer models.
• GT 3 Pro: Adds a rotating crown, a speaker for calls, and a newer heart rate sensor. The titanium version is similar in price to the GT 2 Pro at launch.
• Watch GT Runner: Lighter (38.5g) and focuses on running metrics, but uses a polymer case instead of titanium.
• Huawei Watch 3 Pro: If you need LTE and a full app store, this is the one, but it has shorter battery life (5 days) and costs more.

For most people, the GT 3 Pro is a better buy than the GT 2 Pro if you can find it at a similar price, because it has a speaker and a newer sensor. However, if you find a great deal on the GT 2 Pro, it still offers excellent battery life and durable materials.

Frequently Asked Questions

Is the Huawei Watch GT 2 Pro still worth buying in 2025?

Yes, if you can find it at a discount. The hardware is still premium, and the battery life remains excellent (up to two weeks). However, it lacks a speaker for calls and has no third-party app support, so if you need those, look at the GT 3 Pro or Watch 3 series.

Can the GT 2 Pro measure blood pressure?

No, it does not have a blood pressure monitor. It has an SpO2 sensor for blood oxygen, but blood pressure is not supported. Huawei has a separate watch (Watch D) that measures blood pressure with an inflatable strap.

Does the GT 2 Pro work with iPhone?

Yes, it works with iOS via the Huawei Health app. You can receive notifications, track workouts, and see health data, but you cannot reply to messages from the watch, and some features like NFC payments are not available on iOS.

How accurate is the GPS on the GT 2 Pro?

The dual-band GPS (L1+L5) is quite accurate, typically within a few meters in open areas. In dense urban environments, it is better than single-band GPS, but it can still drift in deep canyons. For most runners, the accuracy is sufficient.

Can I make phone calls with the GT 2 Pro?

You can answer calls via the watch’s speaker and microphone, but you cannot initiate calls from the watch unless you use the phone’s dialer. The watch uses Bluetooth to relay calls from your phone. Note that the GT 2 Pro does have a speaker, contrary to some early leaks that said it did not.

Alternatives to the GT 2 Pro

If you are looking for a similar watch but with more features, consider these alternatives:

• Huawei Watch GT 3 Pro: The natural successor with a speaker, newer sensor, and rotating crown. It also has a titanium version.
• Garmin Venu 2: If you want more advanced fitness metrics and a larger app store, Garmin offers a similar premium build and better software.
• Amazfit GTR 3 Pro: A cheaper option with similar materials (stainless steel) and good battery life, but less accurate GPS.
• Samsung Galaxy Watch 5 Pro: If you use Android, this offers a full app ecosystem and advanced health tracking, but battery life is shorter (about 3 days).

Each of these has trade-offs in battery life, app support, and price, so your choice depends on what you value most.
