Design and Display

The Pixel Watch 3 brings a more polished design and larger screen. It comes in two sizes (41 mm and 45 mm) with a round, bezel-free Actua display. The 45 mm model offers 40% more screen area than the Pixel Watch 2, providing ample room for widgets and notificationsstore.google.com. The display has been significantly upgraded: it uses an AMOLED-LTPO panel with up to 2,000 nits peak brightness, double that of its predecessordcrainmaker.com, freditech.com. In practice this means the watch is easy to read in bright sunlight and offers an immersive look for watch faces and apps. Despite the increase in size, the watch maintains a minimalist, sporty look that fits both casual and professional styles.

Two sizes, multiple bands: 41 mm and 45 mm cases, each with swappable straps.

Display: Always-on AMOLED screen; 45 mm model has ~40% larger screen area than Pixel Watch 2store.google.com.

Brightness: Up to 2,000 nits for excellent outdoor visibilitydcrainmaker.com.

Design: Round, edge-to-edge glass with a single side button and crown for navigation.

Battery Life and Charging

Battery life has long been a challenge for full-featured smartwatches. The Pixel Watch 3’s 45 mm model comes with a 35% larger battery than the prior generationdcrainmaker.com. In normal use (always-on display mode), it reliably delivers around 24 hours of life on a full charge. Using the built-in Battery Saver mode can extend this up to 36 hours by limiting background activity. In real-world testing, users report seeing about 36 hours of operation (roughly 1.5 days) on the larger model with mixed activity (notifications, a few workouts, always-on display)androidcentral.com, dcrainmaker.com. The smaller 41 mm version, with a slightly smaller battery, typically lasts closer to the 24-hour mark. All models can recharge rapidly: Google says the new charger charges about 15% faster than before, reaching 80% in roughly 30–40 minutes.

Battery specs: ~24 hr typical (always-on), up to ~36 hr in low-power modestore.google.com.

Real-world usage: Many users report roughly 2-day (36 hr) runtime on the 45 mm modelandroidcentral.com.

Charging: Fast charging support (≈80% in ~30–40 minutes).

For comparison, competing watches typically last shorter. The Apple Watch Series 9 is rated for about 18 hrs (up to 36 hrs in low-power mode)tomsguide.com, and the Samsung Galaxy Watch 7 around 24 hrs. The Pixel Watch 3’s battery improvements give it an edge in day-long use, though Garmin’s ultra-fit watches still offer multi-day or multi-week endurance for extreme fitness scenariosfreditech.com, freditech.com.

Wear OS 5 & Google AI

The Pixel Watch 3 runs Wear OS 5, bringing a refreshed interface and tighter Google integration. It features Google’s latest AI assistant, Gemini, directly on the wrist. Once set up, the watch can be commanded via “Hey Google” or by pressing and holding the side button. According to Google’s support notes, “With Gemini on Google Pixel Watch, you can turn your smartwatch into a smart, helpful, and personalized companion”. For example, you can say “Hey Google, start my run” or “What’s my heart rate?” and get real-time responsessupport.google.com. Users can also add custom shortcuts to the watch face for quick access to favorite commands. Reviewers report that even complex tasks (like running queries through Gemini) run smoothly on the Pixel Watch 3 despite its older Snapdragon chip, with no noticeable lagandroidcentral.com. This makes the watch adept at voice commands, dictation, and even controlling phone apps (e.g. sending a text from your watch using voice).

Voice assistant (Gemini): Activate via “Hey Google” or the watch button; handles queries, shortcuts, and commandssupport.google.com.

Apps & widgets: Full access to Wear OS apps (maps, messaging, Google Keep, etc.) and watch faces.

It also measures blood oxygen (SpO₂) and even electrodermal activity (EDA) for stress sensingtomsguide.com.

Crucially, Google has added new safety features to the Pixel Watch 3: it is the first smartwatch able to detect a loss of pulse. If the watch senses a sudden flatline in your heart rate, it can automatically call emergency services and share your locationfreditech.com. The watch also supports fall detection and crash detection: for instance, if you’re in a severe car crash or fall, the watch can initiate an SOS call and notify your emergency contacts. All emergency features work with or without your phone nearby (on LTE models or via Safety Signal)support.google.com.

Fitness and Sports Tracking

For fitness enthusiasts, the Pixel Watch 3 offers major upgrades. It now includes a Workout Builder and guided workouts on the watch itself, with real-time audio and haptic pacing prompts. Runners get access to advanced metrics: the watch measures running cadence, stride length, ground contact time, vertical oscillation, and moredcrainmaker.com. These efficiency metrics (and others like PR tracking for fastest 5K/10K times) sync to Fitbit’s mobile app, giving a deep analysis of your runs.

The Pixel Watch 3 also introduces Cardio Load and an enhanced Daily Readiness Score. Cardio Load calculates how hard your workouts tax your cardiovascular system, while Readiness (now available to all users) uses your recent sleep, heart rate variability, and activity to suggest whether you should train hard or restdcrainmaker.com. Unlike before, you don’t need a Fitbit Premium subscription to see your Readiness Score on Pixel Watch 3 – Google made it free for all users. (A Fitbit Premium plan can still add extra guided programs and insights if desired.)

Workout tracking: Auto-detects many activities; create custom interval workouts on watch or app. Offers 40+ built-in exercise modes.

Running insights: Real-time coaching (pace alerts), plus post-run analytics: cadence, stride, vertical oscillation, ground contact timedcrainmaker.com.

Fitbit metrics: Resting HR, Active Zone Minutes, stress and sleep tracking. Smart sleep detection automatically enters battery-saving mode when you fall asleep to extend battery.

AI coach (Fitbit Premium): Optional coaching plans and run recommendations driven by Google AI (Gemini), e.g. suggested workouts based on past runs and Readinessdcrainmaker.com.

Smart Home and Connectivity

Beyond fitness, the Pixel Watch 3 tightly integrates with Google services and smart home gadgets. You can control smart devices right from your wrist. For example, the watch can display a live feed from your Nest camera or even act as a Google TV remote. Other Pixel-specific features include using the watch as a “Find My Phone” trigger for Pixel phones, or even unlocking a paired Pixel phone, thanks to new Ultra-Wideband (UWB) supportdcrainmaker.com. If you have a compatible smart lock or car, Pixel UWB can unlock those as well.

On the communication front, all models support Bluetooth calling (with built-in speaker and mic). You can answer calls on the watch, though reviews note the in-call audio quality is only fair – some users report the speaker sounds “choppy”freditech.com. The watch also supports LTE (on cellular models) for phone-free connectivity, and NFC for Google Pay.

In summary, the Pixel Watch 3 not only tracks your health but can help control your digital life: stream music from YouTube Music, check Google Maps, send messages, set reminders – all from your wrist.

Pixel Watch 3 vs. Competitors

The Pixel Watch 3 now competes with the biggest players in smartwatches. Here’s how it stacks up:

Pixel Watch 3 vs Apple Watch Series (9/10): The Pixel Watch 3 starts at $349 (41 mm, Wi-Fi) versus $399+ for Apple Watch 9 (the direct counterpart). Both come in 41/45 mm sizes and have brilliant 2,000-nit AMOLED screens. The Apple Watch uses Apple’s S9 chip and watchOS, while Pixel uses Qualcomm SW5100 and Wear OS. The Pixel Watch offers similar fitness sensors (heart rate, ECG, SpO₂, skin temperature), and even adds electrodermal (EDA) sensingtomsguide.com; Apple has an altimeter instead. Battery life is slightly better on Pixel (about 24 hr normal vs 18 hr on Apple)tomsguide.com. The Pixel’s integration with Google apps contrasts with Apple’s tighter iPhone ecosystem (Siri now works offline, but things like its SpO₂ sensor have restrictions on US models). Overall, Pixel is the cheaper option with full day battery, while Apple remains the standard for iPhone users.

Pixel Watch 3 vs Samsung Galaxy Watch (7/8): Both use Wear OS 5 and similar specs (2GB RAM, 32GB storage, 2,000-nit AMOLED). The Pixel Watch 3 is slimmer and more minimalist, while the Galaxy Watch 7/8 has a squircle shape and a (fully digital) rotating bezel. The Galaxy runs Samsung’s One UI 6 over Wear OS and offers unique features (like Samsung Health integration). In fitness tracking, Samsung covers more activities (over 100 exercise modes vs Pixel’s ~40thegadgetflow.com) and includes sensors like skin temperature. On pricing, Galaxy Watch is often discounted (e.g. ~ $250–300 on sale), making it very competitive. Importantly, Samsung lets you use all its health features without any subscription, whereas the Pixel Watch leverages Fitbit Premium for the most advanced insights. Battery life favored Pixel’s largest model: in head-to-head testing the 45 mm Pixel lasted ~48 hrs, while the Galaxy Watch 7 managed ~24 hrs. Connectivity-wise, Pixel Watch integrates deeply with Google devices (you can unlock your Pixel phone or control Chromecast/Google TV from it)thegadgetflow.com, whereas Galaxy Watch offers extra perks on Samsung phones (e.g. Galaxy AI messaging). In short, if you’re in the Google/Android ecosystem (especially a Pixel phone), Pixel Watch 3 is a top choice; Galaxy Watch excels for Samsung phone owners and those wanting maximum sport modes.

Pixel Watch 3 vs Fitbit-only watches (Sense/Versa): Prior Pixel Watches were essentially Fitbit smartwatches under the hood. The Pixel Watch 3 takes this further: it has more processing power, a better screen, and runs Wear OS apps – features Fitbit standalones lack. However, Fitbit devices like the Sense 2 still have longer battery life (4–6 days) and slightly deeper health sensors (e.g. stress sensor). The Pixel Watch 3 is for those who want both Fitbit’s health tracking and the full smartwatch experience (apps, Assistant, voice calls), whereas Fitbit’s own watches are more fitness-oriented.

Pixel Watch 3 vs Garmin and Others: If raw battery life is your top priority, Garmin Venu 3 (up to 14 days) or Amazfit (3+ weeks) will beat any Pixel Watch. But Garmin’s benefits come at the cost of a smaller app ecosystem and no Google Assistant. For a modern, “smart” wearable with flashy AI and safety features, Pixel Watch 3 leads its class; for extreme battery or hardcore fitness, Garmin is still kingfreditech.com, freditech.com.

Setting Up and Using the Pixel Watch 3

Getting started with the Pixel Watch 3 is straightforward for Android users. Simply pair it with an Android phone (a Pixel phone is not strictly required, but some features like hold-to-answer calls or on-watch GPS mapping work best with the latest Pixel devicesdcrainmaker.com). The Google Pixel Watch app on your phone handles initial setup and syncing Fitbit data. From there, you can customize watch faces, install apps from the Play Store, and enable Fitbit sleep tracking. A few tips:

Charge fully before first use: The watch should reach 100% charge (takes about 1 hour) for calibration.
Customize fallbacks: In Settings > Safety, confirm your emergency contacts so Crash/Fall detection can reach them.
Explore Health Permissions: Make sure the Fitbit app has permissions for heart rate, sensors and location to get full tracking accuracy.
Enable Gemini: Check that the watch’s Assistant settings are active to use “Hey Google” and the Gemini app.
Try workouts: Use the Fitbit or Workout app on the watch to start an exercise; note how guided haptics help during runs.

These steps ensure you leverage the Pixel Watch 3’s most unique features.

Conclusion

The Google Pixel Watch 3 refines and builds upon Google’s original Wear OS smartwatch vision.
