El Google PixelWatch 4 It's official, and it arrives with the most ambitious leap in the family: a new screen, a larger battery, a different charging system, and Gemini AI integrated as standard. Two sizes, 41 and 45 mm, and a design that remains circular but hides key changes to improve battery life, visibility, and safety features.
During the presentation, Google emphasized that it is the deepest renewal of its smartwatch to date, and on paper it shows: noticeably thinner bezels, a maximum brightness of 3.000 nits, 25% faster charging, satellite SOS (in limited markets for now), and the possibility of replace the screen and battery with a more accessible mechanism than in previous generations.
Actua 360 Display: More usable area and up to 3.000 nits
The absolute star of the show is the new panel. We're talking about a 320 dpi AMOLED LTPO which Google calls Actua 360: physically domed, with adaptive refresh rate from 1 to 60 Hz and protected by Corning Gorilla Glass 5This redesign reduces the bezel around a 15-16% compared to the previous generation, which translates into up to 10% more active area in the same case diameter.
Visibility in sunlight takes a very noticeable leap: the Pixel Watch 4 achieves peaks of 3.000 nits50% more than the Pixel Watch 3's 2.000 nits, so reading notifications or maps in bright sunlight is no longer a challenge. Furthermore, the panel retains the option to always-on display and DCI-P3 color coverage for more vibrant watch faces and apps.
Design and materials: 100% recycled aluminum and elegant finishes
Google maintains the circular silhouette with curved glass, but now the box opts for 100% recycled aluminumLightweight and durable. Available finishes include Matte Black, Polished Silver and Champagne Goldcombined with new Active Band made of soft-touch fluoroelastomer in colors ranging from Obsidian to more striking options like Lemongrass.
Ergonomics remains one of its strengths: the thickness is around 12,3 mmAnd the weight remains manageable (around 31g for the 41mm version and 37g for the 45mm version, without the strap). The haptic feedback crown and side button round out the interaction. comfortable and precisewith a scrolling system that is both practical and satisfying.
Hardware and performance: Snapdragon W5 Gen 2 with AI coprocessor
Inside, the Pixel Watch 4 features Snapdragon W5 Gen 2, accompanied by a coprocessor Cortex-M55 Responsible for artificial intelligence and energy efficiency tasks. They are maintained. 2 GB of RAM y 32 GB eMMC storage, enough for apps, music and watch faces without depending on the mobile.
In practice, the system feels agile opening appsnavigating between cards and switching between spheres. AI support reduces latency in dictation and responses, and the system takes advantage of variable screen refresh to save energy when maximum fluidity isn't needed.
Longer battery life and new side charging: more hours and 0-50% in 15 minutes
There are two batteries depending on size: 325mAh (41mm) y 455mAh (45mm)With an always-on display, Google talks about 30h in the small and 40h In the larger version, with power saving activated, the 45mm version can stretch much further depending on usage, as indicated by initial tests. Results in approximately two and a half days in moderate scenarios.
The charging system changes completely. Goodbye to the classic magnetic dock: now a side cradle with two pins on the side of the box. The promise is a charges 25% faster, with times of 0-50% in 15 minutes and full load between 45 and 60 minutes Subject to conditions. Note: Not compatible with previous generation chargers.
State-of-the-art connectivity (and satellite SOS)
The connectivity is among the most comprehensive in an Android wearable: Bluetooth 6.0, Wi-Fi 6 (802.11ax 2,4/5 GHz), NFC for payments with Google Wallet, UWB extension (ultra-wideband) and versions with 4G LTE/UMTS to function without a mobile phone. As a key new feature, the watch adds SOS by satellite In LTE models, designed for emergencies when there is no mobile or Wi-Fi coverage (currently only available in some countries).
The positioning also improves: it incorporates Dual-frequency GNSS (L5) For more precise routes in cities and forests. Depending on the region, you can combine GPS, Galileo, GLONASS, Beidou and QZSSwhich translates into more stable tracking in complex environments.
Sensors and health: full arsenal with ECG, SpO2 and cEDA
The Pixel Watch 4 inherits and refines the most comprehensive set of sensors in the range: compass, altimeter, barometer and magnetometer for outdoor use; a sensor multipath optical heart rate high precision; electrical sensors ECG compatible; measurement of oxygen saturation (SpO2) with red/infrared light; skin temperature sensor; accelerometer and gyroscope three-axis; and ceDA sensor to estimate the body's stress-related response.
The electrocardiogram can be performed in a quick (around 30 seconds) By resting the fingertip on the crown, the cEDA sensor provides data to identify moments of tension and offer stress management tools via Fitbit. As always, these measurements are geared towards wellness and fitness, not medical or diagnostic uses.
Wear OS 6 and Gemini: AI that activates when you raise your wrist
Premieres WearOS 6 with a design Material 3 Expressive more colorful and clear, and new features like AOD more widespread in apps. The big everyday difference is the Gemini Deep IntegrationThe assistant can be activated simply raising the wrist to speak without giving a prior command, gaining immediacy in responses and suggestions.
Gemini appears in Gmail, Calendar, and more services to offer quickly answersSummaries and contextual actions. Some AI functions and smart responses may be limited by country and by phone (certain features are enhanced when paired with a Pixel phone), but the basic experience is smooth and practical on any compatible Android device.
Repairability and durability: replaceable screen and battery
A new feature that makes a difference in the medium term: the Pixel Watch 4 is the first Google watch that allows Easily replace the screen and batteryWith simplified access via screws, the lifespan is extended and potential interventions are made cheaper compared to generations where the only solution was to replace the entire clock.
In terms of durability, the device boasts IP68 and 5 ATMTherefore, it can withstand immersion for recreational swimming. As always, water resistance is not permanent and may change. diminished by impacts or wearAfter exposure to water, it is advisable to dry the watch and strap to avoid skin irritation.
Sizes, straps and comfort
The Pixel Watch 4 is offered in Two diameters: 41 and 45 mmBoth have bodies made of recycled aluminum. fluoroelastomer sports straps They maintain the brand's quick-release anchoring system and are included. two sizes The Active Band comes in a box to fit most wrists. In terms of feel and fit, the Active Bands are comfortable to wear all day, while sleeping, or during workouts.
The user experience on smaller wrists is better with the 41mm model due to ergonomics, while the 45mm model offers more autonomy and screen surface areaBoth share the same SoC, sensors, storage, connectivity, and panel, so the choice will depend on preferred size and battery needs.
Sport and metrics: 40 modes, improved profiles, and Fitbit Morning Brief
For training, the following are included: 40 exercise modes (such as running, cycling, HIIT, yoga, or racket sports), with detailed metrics and advanced tools for runners. Fitbit provides a Morning Brief which summarizes sleep, preparation, cardiovascular load and goals for the day, helping to adjust effort sensibly.
Those who wish to delve even deeper have the option of Fitbit Premium (paid), with more personalized plans and recommendations, although the basic functions of recording, analysis and trends are extensive without a subscription and are enough for most of users.
Quick comparisons: Galaxy Watch and Apple Watch in the rearview mirror
In front of Samsung Galaxy Watch 8 ClassicThe Pixel offers two sizes (41/45 mm) compared to the Classic's single 46 mm size, which could be key for those with smaller wrists; Samsung is proud of its physical rotating bevel and more generous storage options in some models, but Google is fighting back with Gemini integrated and its ecosystem.
If we look at Apple WatchGoogle's proposal shines as the most polished option for Android, with WearOS 6Greater integration with Google services and an overall balance in design, display, and sensors. Apple remains strong in advanced health within its ecosystem, but the Pixel Watch 4 is the natural reference in Android.
Price and Availability
The family starts with four variants based on size and connectivity. official prices they look like this: 41mm Wi-Fi: €399; 45mm Wi-Fi: €449; 41mm LTE: €499, and 45mm LTE: €549. The Reservation is available and the units will begin arriving from October 9 in the planned markets.

Compatibility, security, and important notes
The clock works with Android and requires the Google Pixel Watch app and a Google account. On LTE, it requires data plan with compatible carrier, availability varies by region. Features may include: ECG, SpO2 o SOS by satellite not be active in all countries since launch.
Remember that wellness metrics (heart rate, SpO2, skin temperature, etc.) are geared towards fitness and general healthThese are not diagnostic tools. The accuracy of UWB, GPS, and connectivity depends on... distance, orientation and obstaclesCharging times and battery life are affected by usage, apps, temperature, and battery age.
What's different from the Pixel Watch 3
If you're coming from the Pixel Watch 3, you'll notice differences in the screen (3.000 nits versus 2.000), in active area (thinner bevel ~15-16%), new cargo cradle faster (incompatible with older chargers), and the presence of Gemini with wrist raise activationFurthermore, the Model 4 incorporates the possibility of battery and screen repair and they add SOS via satellite on LTE.
In the technical specifications, the Pixel Watch 3 featured Snapdragon W5 Gen 1Wear OS 5, Bluetooth 5.3 and batteries of 307mAh (41mm) y 420mAh (45mm)with official figures of 24 hours with AOD and up to 36 with power saving mode. Charging times varied depending on the percentage, with approx. 24-28 minutes 50% and 60-80 minutes to 100% using the USB-C charger and a recommended adapter.
Charging and accessories: useful notes
The new side-pin system changes the desktop routine: the clock leans to one side It's in an alarm clock format, and the software displays alerts if it detects that it's incorrectly placed on the base. It's a small detail, but very practical to avoid false charges.
In previous generations, Google offered a magnetic USB-C charger with a 1m cable and certified speeds using 30W adapters (sold separately). Now, with the faster side cradle, the aim is to reduce daily waiting times, which is welcome considering the typical cycles of autonomy of a powerful smartwatch.
Resilience and sustainability
In addition to Gorilla Glass 5 and the IP68 and 5 ATM sealsGoogle maintains its commitment to recycled materials: the chassis uses 100% recycled aluminum And, in line with the brand's initiatives, priority is given to components and packaging with a smaller footprint (as we already saw in the previous generation with rare earths and even recycled tin in plates and plastic-free packaging in its ecosystem).
As with any wearable, water resistance is not a permanent condition and may be reduced by impacts or repairsIt is also worth remembering that it is not suitable for high temperature water or high speed impacts with water.
User experience: what changes on a daily basis
Beyond the technical specifications, the most noticeable leap is the actual screen visibility and Gemini's instant response. The "raise to talk" feature eliminates the need to use voice commands and transforms the watch into a more natural assistant. Combined with improved haptic feedback and a more powerful speaker, the interactions are clearer and less intrusive.
In sports, the dual-frequency GPS better stabilizes urban routes and changes in pace, and the multi-path heart rate sensor refines peaks and transitionsAutomatic detection of common activities (running, walking, cycling) adds convenience, and the new automatic water lock Avoid accidental touches while submerging.
For those who prioritize security features, the combination of Pulse Loss Detectionfall detection and SOS by satellite (when available in your area) enhances the watch's value in critical situations. It's a layer you'll hopefully never have to use, but that makes a difference.
If you're coming from a Pixel Watch 2 or 3, the upgrade is worthwhile if you value larger screen, better brightness, faster charging, more integrated AI, and repairabilityIf your absolute priority is extending battery life for many days, there are alternatives with longer autonomy, but you lose the deep Google integration and WearOS 6.
The Pixel Watch 4 aims to be the Reference Android smartwatch For those who want a balance between design, health features, and a smarter software experience, with room for improvement in absolute battery life, yes, but with many lights where it really matters.
