The Ultimate UK Guide to Huawei Watch Models: Which Series Do You Own?
If you’ve ever tried to figure out the exact difference between a Huawei Watch GT, a Pro variant, or a classic numbered series, or wondered why a replacement strap designed for a 46mm GT4 won’t lock onto a 41mm model, you are definitely not alone.
Whether you are trying to figure out exactly which model is sitting on your wrist, looking to buy your next tracking companion, or trying to source the exact replacement accessories that fit your casing, this enthusiast breakdown has got you covered.
How to Identify Your Huawei Watch: Finding Your Model
Before you order a replacement screen, purchase a screen protector, or buy a fresh strap, you need to know exactly which Huawei model is on your wrist. Because Huawei releases different case sizes for almost every generation (like the 46mm vs. 41mm variants), guessing can easily lead to buying the wrong accessory.
Here is how our workshop technicians identify every Huawei device that comes across our benches:
Method 1: Check the Rear Glass Casing (Most Common)
Flip your watch over. Most Huawei models have their specific regulatory model code (such as SPG-B19 for the GT4 46mm or JPT-B19 for the GT3 46mm) laser-etched in a circular pattern around the central optical heart rate sensor.
Method 2: Check the Settings Menu (The Foolproof Way)
If the text on the casing back is too faint to read, let the software do the work:
Press the physical top crown button on your watch to wake the screen and open the app list.
Scroll down, select the Settings gear icon, and tap System & Updates.
Tap About.
Here, you will see your exact Model Name (e.g., HUAWEI Watch GT 4) alongside your MAC address and Model number.
Method 3: Check the Huawei Health App
If your watch screen is completely broken or flat:
Open the Huawei Health app on your paired smartphone.
Tap the Devices tab at the bottom of the screen.
Your connected watch's exact model name and size variation will be listed right at the top of the paired device card.
Anatomy of a Smartwatch: What Is Your Huawei Watch Made Up Of?
Have you ever wondered what actually happens underneath the glass when you swipe your screen or track a workout? To the untrained eye, a Huawei watch is just a single sealed unit. On our workshop benches, we see it as a delicate, multi layered sandwich of high end components.
Understanding these physical layers makes it easy to understand what has failed on your device and whether you need a quick outer glass repair or a deeper internal fix.
The Bezel Ring (Outer Armour)
The outermost frame of your watch. On premium models like the GT3 Pro or GT5 Pro, this is cut from exceptionally hard titanium or nanometer crystalline ceramic. On the classic GT series, it is typically polished stainless steel. This ring acts as a defensive wall to absorb the brunt of side impacts.
The Lens & Digitiser Assembly (The Glass & Touch Layer)
This is the part that gets cracked. The Lens is your protective outer glass. Standard editions feature ultra-hard tempered glass, while the premium Pro series upgrades to high strength Sapphire Crystal (which is nearly impossible to scratch but can still fracture under a direct drop). Bonded directly underneath this glass is the Digitiser, a microscopic touch sensitive grid that registers your finger taps and swipes.
The Display Panel (AMOLED)
The screen itself. Huawei uses vibrant, high density, ultra bright AMOLED panels across their entire modern smartwatch lineup. These screens offer incredible contrast and deep blacks, but they draw more battery power when "Always On Display" mode is active.
The Motherboard & Sensors
The brain of the watch. This compact board is packed with Huawei's custom processors, Bluetooth controllers, and high accuracy GPS antenna arrays. When we carry out a screen repair, our main goal is to safely swap the damaged display while keeping this delicate motherboard completely untouched and dust-free.
The Battery Cell
A highly dense Lithium-ion battery. Huawei smartwatches are famous for their industry leading battery life (sometimes lasting up to 14 days on a single charge). However, after years of heavy charging cycles, these cells will gradually lose their capacity, causing your watch to drain faster or shut down unexpectedly.

Huawei Watch GT Series: The Flagship Fitness Companions
If your watch has a beautifully polished stainless steel, titanium, or ceramic bezel, features physical side buttons (often with a rotating digital crown), and boasts an outstanding battery life of up to two weeks, you are wearing a Huawei Watch GT. Spanning from the legacy GT and GT2 up to the modern GT3, GT4, and GT5, this is Huawei's most popular tracking line in the UK.
The Real-World Hardware
The GT series packs premium materials into a highly refined chassis. However, because these watches are worn daily for workouts, manual work, and outdoor training, they take a massive beating. If your screen has cracked, bled black ink, or lost touch sensitivity, booking our professional mail-in screen replacement service will safely restore your watch casing.

The Accessory Configuration
The Huawei GT series utilizes standard Quick-Release watch pins, making strap swaps incredibly easy. To change up your style, you simply compress a tiny metal latch on the underside of the band. It is critical to match your watch's case size to the correct strap width:

Huawei Watch Numbered Series: The Premium Smartwatch
If your watch feels a bit heavier, runs on a more advanced operating system (with access to eSIM and cellular calling), and features a highly polished classic timepiece design, you are wearing a model from the Huawei Watch 3, Watch 4, or Watch 2 family.
The Real-World Hardware
These devices bridge the gap between dedicated sport trackers and full-fledged standalone smartwatches. Because they feature a more complex motherboard, they are highly sensitive to impact damage and internal moisture. If you have cracked your screen or damaged your display, our mail-in workshop technicians can carry out an expert screen swap to get your watch back on your wrist.
