Design and screen
Change compared to previous models
The drawing remains familiar (dome, roundness assumed), but the important thing is played in the details: refined edges of around 15 %, active surface +10 %, and – structuring novelty – a watch designed to be repaired: battery and screen replaceable with standard screws, ifixit in support. It is a change of posture at Google, which extends the real life of the object.
Size, resolution, brightness, Gorilla Glass / Sapphire?
- Actua 360 AMOLED LTPO screen, up to 3,000 brightness, readable in full sun.
- Adaptive frequency 1–60 Hz with Always – on.
- CORNING GORILLA GLASS 5 3D custom glass, resistance 5 ATM and IP68.
- The two sizes (41 and 45 mm) share the same density and the same display characteristics.
In use: 3,000 nits change everything for the readability of the handlebars, hiking or on a terrace at noon; Complications remain readable without broken wrist.
New colors and bracelets available
Sober and easy -to -grant combinations (polished/iris silver, golden champagne/lemon green, matt black/volcanic black, etc.), with a whole range of renewed bracelets. The ties remain simple, thought to alternate sport and office.
Performance and system
New processor (Qualcomm or House?)
The Pixel Watch 4 goes to the Snapdragon W5 Gen 2, associated with a Cortex -M55 co -processor dedicated to light and AI tasks. Beyond the figures, the interest is twofold: energy efficiency and new capacities (including the management of emergency messaging per satellite side on the platform side).
Memory and storage
2 GB of RAM and 32 GB of EMMC storage, sufficient for offline playlists, cards and sport apps.
New under Wear OS + Gemini (integrated AI)
- Wear OS 6 with Material 3 expressive: more contrasting interfaces, denser complications, fluid gestures.
- Gemini replaces the assistant: we talk, we raise the wrist (“Raise -TO – Talk”), we get contextual responses and multi -APPS actions.
- Deployment of Gemini on Wear OS started in July 2025, now generalized.
Concretely: we dictate an SMS and Gemini offers a response adapted to the content of the wire; We ask for a route, he refers to Maps on the watch; We capture a quick note without taking the phone.
Health and Sport
Heart monitoring and ECG
The Fitbit base is solid: multipoint optical sensor, ECG, SPO2, long -range skin temperature and skin conductance sensor (AEDC). Rhythm alerts and ECG remain accessible in a crown torsion.
Improved sleep monitoring
Sleep algorithm revised with a more useful morning ratio: phases, recovery, training adjustment suggestions. Gemini’s AI should adjust the plans to the quality of the night, which is more interesting than a simple score. A well -being coach IA (US overview in October) will come later to offer evolutionary weekly plans.
New fitness and VO2 max sensors
Google emphasizes the accuracy of the measurements and the recognition of activities (extended automatic detection) rather than adding exotic sensors. GPS double -fequence makes a real difference here for the distance in dense city and the clean trail traces.
Autonomy and recharge
Actual duration of the battery (30–40 h)
- 41 mm: up to 30 hours.
- 45 mm: up to 40 h.
These figures take into account the Always on; They are approximately 25 % greater than the previous generation according to Google.
In practice: a full day with sport + notifications + offline music does not force the end of the evening anxiety on the 45 mm; The 41 mm covers the day + the night of sleep without compromise.
Energy saving mode
The saving mode grows at 2 days (41 mm) or 3 days (45 mm), useful on weekend hiking when cutting the Always – on and 4G.
Type of recharge and time required
Owner side charger, more practical on bedside table: 0 to 50 % in 15 minutes, 25 % faster than before. The horizontal orientation transforms the watch into a mini -office time.
Connectivity and security
Double frequency GPS (more precise)
L1 + L5 for cleaner monitoring in town (urban canyons) and under plant cover; Combined with an updated platform -update front, positioning is gaining stability.
LTE / Bluetooth / NFC
Wi -fi/Bluetooth on all versions, LTE optional, NFC for Google Wallet – The base is complete.
New safety (sos satellite, detection falls)
- SOS by satellite: sending emergency messages and position when there is no longer a cellular network; Free during a launch period (US) then to come and come to come.
- Existing drop -down and safety tools detection are kept, with more direct integration into emergency contacts.
Satellite availability first in the United States; international extension to be confirmed.
Compatibility and ecosystem
Android and iOS compatibility?
The Pixel Watch 4 Android target. The deepest integration is done naturally with a Google Pixel smartphone and the Fitbit – iOS account is not announced as the main platform. (Google does not list iOS in the product sheet.)
Integration with Google Home, Maps, assistant
- Gemini takes control of vocal requests, multi -APPS actions, reminders and “extensions” (access to apps).
- Google Maps natively works on the wrist with guidance and useful offline cards.
- Google Home: Quick control of scenes, handles and lights from the tiles.
The passage to Gemini on Wear Os was formalized and deployed in July 2025.
Optimized third -party applications
Strava, Spotify, Komoot, Adidas Running, Calm… Major publishers have already adopted Modern Wear OS. The Pixel Watch 4 adds better performance and intelligent responses that streamline use in these apps.
Comparative
IMPORTANT: We compare the experience and the usage lines here, not an exhaustive technical sheet.
Pixel Watch 4 vs Pixel Watch 3
- Which changes immediately: readability (3,000 nits vs 2,000), finer edges, autonomy +25 %, loads 25 % faster.
- What we feel on a daily basis: fewer micro -features (clearer haptic, clearer speaker, Gemini more useful than the previous assistant).
- This counts in the long term: screen repairability/battery – a real lasting gesture.
Pixel Watch 4 vs Apple Watch 10
- Screen: Apple has enlarged and refined its Series 10, with larger and brighter screen at the corners; Google responds with 3,000 nits and reduced edges. Two philosophies, two excellent readibilities.
- Health: Apple grows strong (Detection of announced sleep apnea), when Google relies on proactive AI and coaching fitbit. Heart follow -up/ECG is present on both sides.
- Battery: Series 10 stays on ~ 6 p.m.; The Watch 4 Pixel aims at 30–40 h depending on the size.
- Safety: The Pixel Watch 4 inaugurates the SOS by satellite on the wrist (first US). Apple does not offer a native satellite call on the watch to date.
In short: iPhone = Series 10; Android (especially pixel) = Pixel Watch 4. Two solid ecosystems; The striking novelty on the Google side is due to the gemini + satellite + repairability combination.
Pixel Watch 4 vs Samsung Galaxy Watch 7
- Price: Watch 7 leaves often lower (from around $ 300 at launch), but without gemini native at the time; Watch 4 is 399 € in Europe (41 mm Wi -Fi).
- Chip and GPS: Watch 7 on Exynos W1000 with L1+L5; Pixel Watch 4 on W5 Gen 2 with Double – Ferquency GPS too. In both cases, followed much better than previous generations.
- Autonomy: Watch 7 holds 1–2 days according to use; Pixel Watch 4 announces 30–40 h, with prolonged economy mode.
- Safety: Pixel Watch 4 introduces SOS Satellite (US first); Watch 7 remains on the classics (drop detection, cellular emergency calls).
If you are in the Samsung ecosystem, Watch 7 remains coherent; If you want the gemini and the satellite in the long term, the Pixel Watch 4 is the most direct path.
Accessories and personalization
Official and third party bracelets
Sport bracelets in fluoroelastomer, meshes and leathers adapted to aluminum housing. Rapid fasteners encourage alternation office/sport; The third -party offer is wide as soon as it is released thanks to the continuity of the format.
Charging stations
The new side dock transforms the watch into a bedside clock. It’s simple, stable, and – important point – compatible with all types of bracelets, even loops without clasp.
Cases and protections
The Gorilla Glass 5 3D cashes well, but a film or a fine protective telescope will avoid hooks of the door handles. Real interest: preserving repairability for “big” incidents, not for daily micro -scratches.
Busy experience (France)
- Where pre -order: Google Store France and partner brands, delivery from October 9, 2025.
- What size to choose:
- 41 mm if you favor compactness and comfort 24/7 (sleep included).
- 45 mm if you do long sessions (GPS, music) or want 40 h serene.
- Wi-fi or LTE:
- Wi-fi/Bluetooth is enough if you run with the phone or download your playlists.
- LTE if you want to leave the smartphone to the locker room (calls, SMS, data) – and to ultimately benefit from an off -network satellite sos where it will be deployed.
- What we check at the checkout: type of bracelet (sport vs “leather”), a second bracelet with the size that is fine, and the additional charger if you travel often.

Conclusion
The Google Pixel Watch 4 does not make unnecessary noise. It corrects the essential: exemplary readability, credible autonomy, higher level security, and a gemini assistant finally adapted to the wrist. She does not seek to play the bidding of sensors; She polishes the experience. And it does so thinking about the lifespan (repairability) – a point too rare on connected watches. For an Android user – and more a pixel user – it is Google’s most coherent watch to date.
