With its third-generation smartwatch, Nothing’s low-cost sub-brand is hitting harder than before. This is what immediately jumped out of the box.
Design and Build
Each of the three color variations of the Watch 3 Pro has somewhat different weight and size. The Dark Grey weighs 51.9 grams and has dimensions of 25.8 cm (H) x 4.7 cm (W) x 1.44 cm (D). The Light Grey is the lightest of the three at 51.0 grams and has the same dimensions of 25.8 cm by 4.7 cm, but it is somewhat thicker at 1.52 cm. The Orange version weighs 52.4 grams and is the same height and width as the Dark Grey, but it is 1.45 cm deep.
The body is made up of a metal frame and a liquid silicone strap. Because the straps are detachable, third-party or future CMF band choices are possible. The Watch 3 Pro is positioned closer to premium territory than its price category usually requires thanks to its construction method, which consists of a metal body atop a soft-touch strap.
Display
A 1.43-inch AMOLED display with a resolution of 466 × 466 pixels at 326 PPI powers the watch. The highest brightness rating is 670 nits, with an average peak of 650 nits. The interface remains fluid while navigating thanks to the refresh rate of 60 frames per second. With the help of incredibly small bezels, the screen-to-body ratio is 91%. Based on the surrounding environment, auto-brightness dynamically changes in real time.
Static, dynamic, interactive, and Always-On Display watch face options total more than 120. In addition to supporting photo album watch faces and video watch faces uploaded from the companion app, the watch’s AI-powered Watch Face Studio lets users create unique faces.
Health and Fitness Monitoring
The Watch 3 Pro makes the biggest investment in this area. In terms of heart rate, the next generation optical sensor claims to be up to 7% more accurate during activity and up to 3.6% more accurate at rest than the previous generation, capturing smaller fluctuations in blood flow. Heart rate zone tracking, resting heart rate, exercise heart rate, automatic heart rate measurement, 24-hour continuous monitoring, heart rate reminders, and average heart rate computations are all supported.
High-frequency heart rate sampling and improved motion sensors have revolutionized sleep tracking. The watch includes a high-precision mode for deeper analysis that users may activate on demand, detects brief naps, and stages sleep more precisely.
Blood oxygen (SpO2) is continuously monitored around-the-clock, and when values deviate from typical ranges, blood oxygen reminders are sent. Additionally, stress monitoring is available around-the-clock. For women, the watch includes physiological health records with intelligent cycle tracking and prediction.
Using MET (Metabolic Equivalent of Task) values and heart rate data, the Active Score system provides a single weekly activity score. It is benchmarked against a weekly objective of 100 in accordance with international health standards, integrates exercise intensity with total movement volume, and refreshes daily and after each session.
All-day step counts, calories burnt, distance traveled, exercise duration, water intake reminders, and stand-up reminders during periods of inactivity are among the other health tracking features. Additionally, breathing exercises that react to real-time stress and heart rate data are integrated into guided breathing sessions.
Fitness and Sports Features
Each of the 131 sports modes available on the Watch 3 Pro offers specific parameters such as heart rate zone data, calories, pace, and recovery time. Seven of these activities—walking, running, cycling, and rowing—benefit from intelligent automated recognition. The watch notifies the user and fills in the missing data in hindsight if a workout starts without the user manually beginning tracking.
A customized 8–16-week training plan is created by the custom running coach based on the user’s objectives, degree of fitness, and recuperation requirements. Through organized session types like tempo runs, intervals, and steady-state efforts, the strategy aims to increase VO2 max and fat burn. Depending on how the body reacts, the plan changes in real time.
Following a training, the watch creates a personalized summary that includes endurance forecasts for 5K and 10K run distances, load trend analysis, rest time suggestions, and intensity feedback. Because workout panels may be customized, users can highlight the stats that are most important to them.
3D animated warm-up guides that target particular muscle areas before to a run or cycle provide pre-session support, while post-session stretching cues aid in recuperation and lower the chance of injury. The exercise interface has built-in music controls that can be accessed with a swipe without interfering with the current session.
Sensors and GPS
An accelerometer, gyroscope, ambient light sensor, and a combined heart rate and SpO2 blood oxygen saturation sensor are all part of the sensor suite. The dual-band GPS implementation supports both the L1 and L5 signal bands for better positioning accuracy in places with tall structures, dense vegetation, and urban settings where single-band GPS usually deteriorates. GLONASS, Galileo, QZSS, and Beidou SAT networks are all compatible with the system. The rating for continuous GPS use is 17.2 hours. A linear motor is used in the haptic feedback system.
Battery
A 350 mAh rechargeable lithium-ion battery powers the Watch 3 Pro. The breakdown of rated battery life is as follows: 13 days for normal usage, 10 days for heavy use, 4.5 days for heavy use with Always-enabled Display enabled, and up to 60 days for power-saving mode. The rating for continuous Bluetooth calls is 17.9 hours. A proprietary charging line is used for charging, and it takes 99 minutes to fully charge. The watch has an IP68 grade for water and dust protection.
Smart Features and Connectivity
Version 5.3 Bluetooth connection is available. The Nothing X companion app is used to control the watch on iOS 13 and higher and Android 6.0 and above. The main hub for managing settings, viewing comprehensive health metrics (such as stress, SpO2, and VO2 max), customizing layouts, and intelligent health summaries is Nothing X. Apple Health, Strava, and Google Health Connect can all be integrated with the app.
Two powerful MEMS microphones and an integrated speaker enable Bluetooth calling straight from the wrist. More than 100,000 voice samples have been used to train the AI-based noise reduction technology. For easy access, up to 30 contacts can be synchronized. Email and messaging apps in Southeast Asia, East Asia, Europe, and the US offer brief responses of up to 140 characters.
For information retrieval, day planning, and natural language searches, ChatGPT is built right into the watch. The most recent software version is needed to use this feature, which is presently only available with Nothing OS. The Nothing X app offers voice recording with automatic transcription as well.
Every morning, the user can customize the topics of the curated daily digest of interest-based news that is delivered to their wrist by the Essential News function.
Gesture shortcuts, which use motions like a double shake or wrist flip to initiate important activities, enable control of the watch without touching the screen. Recording transcription, news reporting, cloud watch faces, photo album and video watch faces, a watch face generator, breath training, message notifications, music control, timer, stopwatch, alarm clock, emoji message alarms, weather updates, Find My Phone, flashlight, camera remote, reminders, voice assistant, calendar, calculator, and world clock are just a few of the smart features.
