The scene is simple. Clear morning, frank sun. You go run. With the Pixel Watch 3, the screen remains readable, but sometimes requires to seek the shadow. With the Pixel Watch 4, no need: it pierces the light effortlessly, and you return with 20% more battery.

The real jump is there: in use, not in the show.

Display: more readable, bigger, same gesture

• Pixel Watch 3: News screen up to 2000 Nits, Gorilla Glass 5 dome, Fluid AOD.
• Pixel Watch 4: New Actua 360 screen, 3000 Nits, enlarged active surface, refined borders, still made of bombed glass.

In practice: under a summer sun, the stats remain clean, contrasting, and navigation on the wrist is more relaxing. The expansion of useful zone does not change your habits, but makes each micro-interaction more obvious. It's discreet, but decisive.

Autonomy: the point that changes the pixel watch comparison

• Pixel Watch 3: 24 hours with AOD, up to 36 h in economics mode; Quick USB - C load at the cable.
• Pixel Watch 4: 30 h (41 mm) at 40 h (45 mm) with AOD; up to 48/72 h in economics mode; New dock Quick Load: 50% in ~ 15 min, full in 45–60 min.

Concrete uses:

• Dense week: meetings + evening sport + punctual GPS → The 4 holds the day with margin, the 3 growth in the systematic “night load” ritual.
• Weekend hike: the 4 covers a long loop + return without stressing; The 3 requests a passage to the charger between two activities.

It's the “huge surprise”: Google has corrected historical weakness. If “Pixel Watch autonomy” is your n ° 1 criterion, the match clearly leans around 4.

AI and experience: more direct, more contextual

• Pixel Watch 3: Assistant, Recorder, Gmail, Maps, Wallet; Solid and reactive bases.
• Pixel Watch 4: Gemini more integrated, contextual responses and “Smart folds” more relevant, more immediate wrist interactions, always without theater: we raise, we ask, it's done.

Concretely, we dictate a reminder after the warm -up, we filter a call during a session, we launch a route without taking out the phone. Nothing ostentatious; just less friction.

Health and safety: same base, expanded scope

• Shared sensors: ECG, SPO2, Multipath heart rate, CEDA (body response to stress), skin temperature, altimeter, compass. Sleep monitoring, reading, 40+ sports. Detection of pulse loss and emergency call.
• Key new features side 4: double frequency GPS for cleaner traces in dense town or in the forest; SOS by satellite (LTE, availability according to country), to remain reachable outside the coverage. It is the brick that changes the use in the mountains, a sail, or on isolated roads.

Pixel Watch design: assumed continuity

• Two sizes (41 and 45 mm), 12.3 mm thick, 100% recycled aluminum case, Gorilla Glass 5, 5 ATM + IP68 dome. Bracelets and ergonomics remain familiar.
• The 4 refines the sensation: haptic cleaner, better “wedged” buttons, dome always sensual on the wrist. Visually, difficult to distinguish them from a distance - and it is wanted.

Performances and connectivity: what we feel, what we do not see

• Pixel Watch 3: Snapdragon W5 Gen 1 + Co -Co -Co -Cessor M33; Wi -fi ax; UWB; 4G optional.
• Pixel Watch 4: Snapdragon W5 Gen 2 + Co -Co -Co -Cessor M55; Same network bases (Wi -Fi AX, UWB, 4G), but more efficient treatment, better performance maintenance with AOD and continuous sport.

Concrete uses:

• Fractional + music on local + AOD: the 4 remains fluid and loses less battery.
• Carto wrist (MAPS) on urban bicycle: the double -frequency reduces the “jumps” of position at the crossroads.

Should we go from the Watch 3 pixel to the 4?

• Yes, if you want: better readability in full sun, a real day of serene autonomy (or more), cleaner GPS traces, and a safety net in white zone via satellite (if available at home).
• Not essential, if: your use is urban, your sport sessions are short, and the daily burden does not weigh you. The Pixel Watch 3 remains a complete and reliable “Pixel Watch 3”, with the same design language and most of the features.

To go further

Busy experience: how to try before adopting

• Size and comfort: Test 41 vs 45 mm; The 45 offers “Pixel Watch autonomy” superior and broader readability, but the 41 blends better under a shirt.
• Screen in conditions: Take the watch in the store in the store, activate AOD, check the wrist readability.
• Bracelets: Sport (fluoroelastomer) for training, leather/steel for the office. A good bracelet really changes the posture on a daily basis.
• Network and rescue: Check the LTE/Satellite management at your operator and the local availability of SOS functions.
• Ecosystem: If you are already on Pixel and Google services, the 4 magnifies the whole; Otherwise, make sure of an Android 11+ and the key apps you use.

Verdict: useful progress, not rowdyThe Pixel Watch 4 does not reinvent the watch. It reinvents tranquility: more autonomy, more readability, more precision, out -of -network help.

For many, that's exactly what we expected.
