Verdict

The OnePlus Watch is a 46.4mm circular smartwatch featuring a 1.39-inch AMOLED display (454x454 resolution, 326 PPI) housed in a 316L stainless steel case with IP68 and 5ATM water resistance. It runs a proprietary RTOS-based operating system with 4GB of internal storage and a 402mAh battery that provides a standout typical life of up to 14 days, supported by fast charging that offers a day's power in just five minutes. Key characteristics include integrated GPS, heart rate monitoring, SpO2 blood oxygen tracking, and over 110 workout modes, alongside the ability to take Bluetooth calls and control music directly from the wrist. Main pros are its premium build quality, exceptional battery endurance, and responsive interface; however, it is frequently criticized for its lack of third-party app support, absence of an always-on display at launch, and its single large size which may be too bulky for smaller wrists.

OnePlus Watch Review: Needs Work

The Coach review characterizes the original OnePlus Watch as a "frustrating," first-generation device, highlighting a premium 1.39-inch AMOLED display and a 14-day battery life as its main strengths. However, the experience is hindered by "underdone" software, a bulky 46mm design, and an uncomfortable strap system. Key drawbacks include inaccurate, slow-locking GPS and a limited health app that lacks third-party syncing capabilities. Despite these, the watch offers fast Warp Charging and a competitive price point.

The device boasts a high-quality 316L stainless steel design, a 1.39-inch AMOLED display, and fast Warp Charge technology.

XDAKey disadvantages highlighted include a lack of third-party app support, no Always-on Display at launch, and restricted notification interaction. While fitness features like GPS and blood oxygen monitoring are generally accurate, the experience feels more like a high-end fitness tracker than a full-featured smartwatch.

A standout feature is the exceptional battery life, which lasts several days in normal use and charges quickly, providing nearly a full day of power in just 10 minutes. Performance is smooth, supported by a dual-chip architecture that manages energy efficiently. Pros include extensive fitness tracking with over 100 modes, along with practical features like Bluetooth calling and on-board music storage. However, the watch is limited by its closed ecosystem, which lacks third-party app support and NFC payments in some regions. Furthermore, it is only available in a single 46mm size, which may not suit smaller wrists, and some users may find the software less mature than competitors. While the device offers high-end build quality, the review notes occasional inconsistencies in GPS tracking accuracy during outdoor activities. Despite these limitations in functionality, the device serves as a stylish, long-lasting wearable, as described in the CHIP.de video review.

OnePlus Watch Review: A Beautiful Smartwatch with a Major GPS Problem

The OnePlus Watch features a premium 316L stainless steel design with a bright 1.39-inch AMOLED display and impressive 14-day battery life, though it is limited to a 46mm size that may feel bulky. Major issues exist with the GPS, which frequently fails to track routes accurately, and the proprietary software limits functionality, lacking third-party apps and key features like a voice assistant. Ultimately, despite its solid construction, the device feels unfinished for fitness tracking due to inconsistent, or completely missing, data during workouts.

OnePlus Watch Review: A Youthful Mistake?

The Journal du Geek review describes the original OnePlus Watch as a "youthful mistake," highlighting a premium stainless steel design and vibrant 1.39-inch AMOLED display, yet it suffers from unfinished software and limited functionality. While featuring over 110 sports modes and 5ATM water resistance, the proprietary RTOS lacked essential features like a 12-hour clock, third-party apps, or an Always-On Display (AOD) at launch, resulting in a device that felt more like a fitness tracker than a smartwatch. Positively, the device delivers excellent endurance, providing nearly a week of battery life with heavy use, complemented by "Warp Charge" technology that offers a full day of power in five minutes. Despite this, significant drawbacks include inaccurate GPS tracking, buggy health data syncing with the OnePlus Health app, and the inability to respond to notifications. Consequently, the review concludes that the polished hardware is overshadowed by software, making it a difficult recommendation.

Summary of the review

The OnePlus Watch is an underwhelming work in progress

The GQ review characterizes the OnePlus Watch as a visually impressive "work in progress" that prioritizes hardware over software, featuring a premium 46mm stainless steel case and a bright AMOLED display. While the design is a highlight, the substantial size is a drawback for smaller wrists, and the watch severely lacks functionality with no third-party app support or NFC. Despite these limitations, the device boasts exceptional 14-day battery life. Performance-wise, the review highlights significant cons regarding tracking accuracy, withGPS and heart-rate data proving unreliable for serious fitness use. Ultimately, the watch is deemed a stylish but under-featured tracker rather than a full-featured smartwatch, making it difficult to recommend despite its attractive price point.

OnePlus Watch review - TechRadar

The TechRadar review describes the original OnePlus Watch as a premium-looking, competitively priced device featuring a polished stainless steel chassis, a sharp AMOLED display, and exceptional battery life lasting roughly a week with fast charging. Key advantages include its sturdy build quality and impressive longevity, making it a stylish, budget-friendly alternative to high-end wearables. However, the watch is hampered by a limited, proprietary operating system (RTOS) that lacks third-party app support and exhibits first-generation software bugs, such as inconsistent GPS tracking and UI glitches. Furthermore, the 46mm design is considered bulky, and the companion app’s initial Android-only exclusivity restricts its user base. While offering extensive fitness tracking, the device lacks the advanced, deep ecosystem integration found in competitors. It is ultimately recommended for those prioritizing battery endurance and aesthetics over advanced smart functionality.

OnePlus Watch Review - Andrea Galeazzi

Andrea Galeazzi's review of the original OnePlus Watch highlights a well-built device featuring a 1.39-inch AMOLED display and 5 ATM waterproofing at a competitive €159 price point. While the design is deemed premium, the review emphasizes significant, unfinished software limitations, particularly regarding poor notification management and inconsistent fitness tracking. Key pros include excellent battery life (roughly 10% consumption per day), functional Bluetooth calling, and a solid selection of customizable watch faces, all packed into an aesthetically pleasing, durable chassis. However, the experience is hindered by notable cons, such as a bug that limits notifications to only the most recent message, a lack of automatic sleep tracking, and a somewhat unreliable companion app. Galeazzi concludes that while the hardware justifies the price, the software experience feels unrefined and restrictive compared to competitors.

OnePlus Watch review: sleek watch is not yet recommended due to mediocre software

The OnePlus Watch is highlighted as a stylish, well-built wearable featuring a durable stainless steel design, a vibrant 1.39-inch AMOLED screen, and an impressive one-week battery life with rapid charging. Despite this, the experience is hindered by a limited, proprietary operating system that lacks third-party app support, NFC payments, and an always-on display. Functional shortcomings, including imprecise GPS tracking and a basic "OnePlus Health" app, make it more of a premium fitness tracker than a true smartwatch. Additionally, the 46.4mm casing is quite heavy and large, potentially uncomfortable for smaller wrists. Ultimately, the device is recommended primarily for users who prioritize premium aesthetics and long-lasting battery over advanced smart features, according to the review.

Review: OnePlus Watch 2R – the lightest truly good Android Wear experience

The OnePlus Watch 2R is a lightweight (37g), affordable "flagship killer" featuring a durable aluminum case, Panda Glass, and comfortable design, according to a GadgetGear.nl review. It utilizes a "dual-engine" architecture (Snapdragon W5 Gen 1 + BES-2700) and Wear OS 4 to deliver exceptional battery life, with tests confirming 100 hours in Smart Mode and 11 days in power-saver. While praised for its 1,000-nit, 1.43-inch AMOLED display, the watch lacks a rotating crown, uses a proprietary magnetic charger instead of wireless charging, and has a large 47mm footprint.

OnePlus Watch 2 review: Wear OS watch with excellent battery life

The OnePlus Watch 2 features a "dual-engine" architecture combining Wear OS 4 and a low-power RTOS to deliver an industry-leading 100-hour battery life in Smart Mode. This design allows for full functionality without the daily charging required by competitors, while boasting a durable stainless steel chassis and a 1.43-inch AMOLED screen. However, the top crown does not offer scrolling functionality, and the device is only available in a 46mm size, which may feel bulky on smaller wrists. Despite its strong performance, the watch lacks advanced health tracking features such as an ECG, fall detection, and body temperature sensors, which are common in similar devices. It does, however, provide accurate health metrics, including dual-frequency GPS and heart rate monitoring that rivals Garmin.

Finally a Wear OS with long battery life - Review - Tweakers

The Tweakers review of the OnePlus Watch 2 highlights its "Dual-Engine Architecture" as a major breakthrough for Wear OS, featuring a Qualcomm Snapdragon W5 Gen 1 for heavy tasks and a BES2700 chip for low-power background activities. This design delivers an impressive 100-hour battery life in Smart Mode and up to 12 days in Power Saver Mode, significantly outperforming competitors. Key pros include exceptional battery endurance, a premium stainless steel case with sapphire crystal, fast VOOC charging, and accurate dual-frequency GPS. Conversely, the 47mm size is considered bulky, and it lacks advanced health sensors like ECG, skin temperature, and fall detection. Furthermore, the rotating crown is not functional, and the device is not compatible with iOS. Ultimately, the Watch 2 solves the daily charging issue for Android users but falls short of offering a complete, advanced health tracking package. It is positioned as a strong, rugged option for users who prioritize battery life over specialized health metrics.

OnePlus Watch 3 43mm review: Not just smaller

The OnePlus Watch 3 43mm offers a more refined, comfortable fit for smaller wrists, featuring a lighter 37.8g stainless steel design and a slimmer 11mm profile. A major pro is its design shift, avoiding the bulky, "cartoonish" look of previous 46mm models, making it ideal for daily wear and sleep tracking. Utilizing a dual-engine architecture, the watch balances high-end Wear OS features with efficiency, delivering up to 60 hours in smart mode despite a smaller 354mAh battery. It boasts fast charging, providing a full day of use in 10 minutes, though the lack of wireless charging remains a consistent con. Technical trade-offs include the omission of a skin temperature sensor and sapphire crystal display. While offering advanced health metrics like HRV tracking, the watch lacks ECG monitoring and fall detection, and the rotating crown remains purely aesthetic.
