I\u2019ve tested out both the 43<\/a> and 47mm version of OnePlus Watch 3. In this article I compare the smaller iteration versus the 41mm Google Pixel Watch 3. Both are slim, unisex, lightweight smartwatches with polished designs and plenty of health tracking. On the surface, they look similar. But after a few days of switching between them, the differences became clear. One is all about comfort and battery life. The other pushes deeper into health metrics.<\/p>\n

The OnePlus Watch 3 feels practical and straightforward. It\u2019s light on the wrist, tracks workouts reliably, and lasts far longer than most Wear OS watches. You miss out on some of the more advanced sensors, but most core features are here. GPS, heart rate, SpO\u2082, and basic health functionality are all well implemented. Plus, you get a few surprise extras.<\/p>\n

Pixel Watch 3 is a more refined experience. The curved glass, slim profile, and tight Google integration give it a premium edge. You also get skin temperature, ECG, cEDA for stress, and deeper health metrics through Fitbit. But it demands more attention. Battery life is short.<\/p>\n

Design and comfort land differently<\/p>\n

Starting off with design, and the OnePlus Watch 3 (43mm) has a clean, round face and a more traditional smartwatch aesthetic. The stainless steel build feels solid, and the watch wears flat and secure on the wrist. It\u2019s light enough to forget about, even during sleep or exercise.<\/p>\n

Pixel Watch 3, on the other hand, goes all-in on style. The domed Corning Gorilla Glass 5 blends into the aluminum case, and the 31-gram weight makes it one of the lightest smartwatches out there. If you like minimalist design, it nails that look. This generation finally introduces a larger 45mm model, but for this comparison, I stuck with the 41mm version to match sizing.<\/p>\n

All things considered, these are two very similar looking watches. Both have a crown and a flat physical button. But the OnePlus has edges that are a bit more defined, whereas the Google device goes for a more rounded look.<\/p>\n

Where the OnePlus wins is in display size. You get 1.32 inches of screen, versus 1.2 inches on the Pixel. Both peak at 2000 nits, but OnePlus gives you a bit more room to view your data.<\/p>\n

\"OnePlus Sensors and health tracking go deeper on Pixel<\/p>\n

Pixel Watch 3 brings a bigger toolkit. You get ECG, skin temperature tracking, cEDA for stress detection, irregular rhythm alerts, and a refined multi-path optical heart rate sensor. It\u2019s one of the most sensor-packed Wear OS watches available, and the integration with Fitbit makes good use of it. There\u2019s also an optional Premium Subscription level with additional health insights, but you don\u2019t really need it as you get plenty as it is.<\/p>\n

The OnePlus Watch 3 (43mm) skips those Fitbit extras but covers the essentials. It tracks heart rate, blood oxygen, sleep, mental wellbeing, barometric data, and more. The tracking is accurate, and the dual-frequency GPS is quick to lock and stays on course. What\u2019s missing is wrist temperature, ECG, and vascular metrics found in the 47mm model. So if you want those extras, you\u2019ll need to opt for the larger iteration.<\/p>\n

Essential reading:\u00a0<\/strong>Top fitness trackers and health gadgets<\/a><\/p>\n

For users who want deeper wellness insights and can tolerate shorter battery life, the Pixel Watch 3 makes sense. For those who just want reliable data without extra fuss, OnePlus gets the job done.<\/p>\n

\"OnePlus Sports tracking is solid across both<\/p>\n

The OnePlus Watch 3 supports over 100 workout modes. Running metrics include cadence, stride length, running power, VO\u2082 max, and recovery scores. I compared its heart rate tracking to a Garmin, and the results were within a beat or two. GPS accuracy was also on point, even in tougher conditions like tree cover or tight city blocks. Plus you get extras, such as running dynamics metrics, with detailed charts and explanations.<\/p>\n

Pixel Watch 3 tracks fewer activities, but makes up for it with automatic workout detection and tight integration with the Fitbit platform. It\u2019s especially strong for casual and intermediate runners. In my tests, the GPS stayed locked in, and distance accuracy was within 200 meters of a high-end Garmin on a 10K run. The lighter weight helps the heart rate sensor maintain a snug fit, which improves accuracy.<\/p>\n

Where the Fitbit falls short is in detailed performance feedback. There\u2019s no training effect, load, or recovery analysis. You\u2019ll get basics and Fitbit\u2019s Daily Readiness Score, but that\u2019s it.<\/p>\n

Granted, neither of these two watches approach Garmin\u2019s as far as sports tracking. But they are more health and fitness smartwatches, whereas Garmin devices are sports watches.<\/p>\n

\"OnePlus Smart features vs staying power<\/p>\n

Both the OnePlus and Google run Wear OS 5 and feel fast. Navigation is smooth, animations are clean, and app support through the Play Store is robust. You get the usual staples like Assistant, Wallet, Maps and messaging.<\/p>\n

Pixel Watch 3 takes it further with ultra-wideband (UWB), optional LTE, and deeper integration with Google services. Assistant is quick, call quality is great, and the whole experience just feels more complete.<\/p>\n

As far as music storage \u2013 the OnePlus Watch 3 (43mm) has 32GB of internal memory, but there\u2019s no built-in option to transfer MP3s directly through the official app or watch interface. Users can enable offline playback using third-party Wear OS apps like Wear Casts, which allow sideloading of audio files.<\/p>\n

In contrast, the Google Pixel Watch 3 supports offline music through streaming services like YouTube Music and Spotify, but this requires a paid subscription. It doesn\u2019t offer native support for local file transfers, though users can upload personal tracks to YouTube Music on desktop and then download them onto the watch as a workaround.<\/p>\n

Battery life \u2013 not that great<\/p>\n

Battery life is still a sticking point. Particularly for the Google device. The Pixel Watch 3\u2019s 307 mAh cell only lasts around 24 hours with the always-on display. The new Battery Saver mode can stretch that to about 36 hours, and charging is 20% faster than before, but you\u2019ll still be topping up daily.<\/p>\n

The OnePlus Watch 3 (43mm) lasts longer. With a 345 mAh battery, you can get up to 60 hours in standard use, and up to 7 days in Power Saver mode. A 10-minute top-up gives you a full day. It\u2019s the less demanding watch, and that matters if you don\u2019t want to think about charging. For really great battery life, opt for the 47mm variant. That one almost doubles what you get on the 43mm version.<\/p>\n

Our takeaway<\/p>\n

The OnePlus Watch 3 (43mm) and Google Pixel Watch 3 are both strong choices in the mid-range Wear OS space. But they suit different users.<\/p>\n

If you want a straightforward watch that nails the basics, lasts for days, and tracks workouts accurately, the OnePlus Watch 3 makes a strong case. It doesn\u2019t have all the bells and whistles, but it\u2019s practical, comfortable, and reliable.<\/p>\n

The Google Pixel Watch 3 is smarter, sleeker and more ambitious. It tracks more health signals, fits tighter into Google\u2019s ecosystem, and offers a polished user experience. But it needs more attention, and some features sit behind a subscription.<\/p>\n

Pick based on what you value more: battery life and simplicity, or deeper insights and a tight Google experience.<\/p>\n
