The Ultimate UK Guide to Google Pixel Watch Models: Comparing the Generations
Google’s Pixel Watch family has redefined minimalist smartwatch design, featuring a stunning "water-drop" 3D domed glass face that blends seamlessly into its casing. From the very first generation to the latest releases, the core aesthetic has remained virtually unchanged.
However, under the hood, the generations are completely different. Google has shifted materials from Stainless Steel to Aluminium, updated bio-sensors, and crucially overhauled the entire charging mechanism. Knowing exactly which Pixel Watch generation you are dealing with is vital before purchasing replacements straps, protective screen layers, or compatible charging cables.
This complete guide, compiled by our specialised UK workshop technicians, provides the definitive comparison matrix and identification tools for every Google Pixel Watch.
How to Identify Your Google Pixel Watch
If you are unsure which generation you own, our workshop team uses three quick, foolproof methods to verify the model instantly:
Method 1: Check the Back Casing (The Charging Ring)
The single biggest technical change between generations was the charging system. The original Gen 1 charger will not power newer models, and vice-versa. Flip the watch over and inspect the rear glass sensor dome:
It is a Pixel Watch 1 if: The circular glass back is completely smooth and unbroken. There are no exposed metal contact points. It charges entirely via wireless induction.
It is a Pixel Watch 2, 3, or 4 if: You see four gold, circular metal pins arranged in a curved row along the bottom half of the sensor dome. These are physical contact points that must align with the charging puck.
Method 2: Check the Settings Menu
If your watch has power and the screen works:
Swipe down on the watch face and tap the Settings gear icon.
Scroll down and select System.
Tap About.
Your official Model Name (e.g. Pixel Watch 2) will be clearly displayed.
Method 3: Check the Regulatory Model Number
If the screen is broken, let the hardware itself reveal the generation. Unclip your strap; inside the recessed curved channel where the strap slides and locks into the watch body, you will find a microscopically laser-etched model number.
Pixel Watch 1: G9FPL (Wi-Fi) or GBZ4S (LTE)
Pixel Watch 2: GD2WG (Wi-Fi) or GC3G8 (LTE)
Pixel Watch 3 (41mm): G3S9A
Pixel Watch 3 (45mm): GRY0T
