Suunto Unveils Race 3S Smartwatch Alongside New AI Coach Subscription Service

Finnish sports watch manufacturer Suunto has officially announced its latest wearable, the Suunto Race 3S. Designed with a smaller form factor, the new device arrives with a notable shift in pricing strategy that has raised eyebrows across the industry. Alongside the hardware release, Suunto has introduced a new subscription service, the Suunto AI Coach, which serves as a centralized hub for advanced app features and data analysis. Following weeks of hands-on testing across diverse athletic environments, reviewers and athletes alike are examining whether the hardware updates and software ecosystem can justify the steep price increase compared to its predecessors.

The Suunto Race 3S introduces several evolutionary upgrades over the existing Race S model, featuring a significantly brighter display, expanded internal storage, and various software feature updates. One of the most notable physical changes involves an upgrade in build materials, with the watch shifting from a stainless steel bezel to a lightweight and durable titanium bezel. The device has been put through rigorous real-world testing across a wide variety of outdoor activities to evaluate its general durability, navigational capabilities, and performance metrics against competing sports watches released around the same time.

What’s New in the Suunto Race 3S

The Suunto Race 3S serves as a direct upgrade to the existing Suunto Race S lineup. Curiously, the release leaves a gap in the product ecosystem, as there was no intermediate Suunto Race 2S model, and the company has not yet introduced a larger companion device bearing the Suunto Race 3 moniker. When questioned about future variants, company representatives offered no comment, leaving the exact roadmap for larger form-factor models open. Meanwhile, the original Suunto Race S continued to receive firmware updates until recently, but the focus for the new generation centers firmly on tangible hardware and software expansions.

Looking closely at the hardware specifications, the Suunto Race 3S brings a substantial list of revisions. Peak display brightness has been doubled from 1,000 nits to 2,000 nits. The protective lens cover material has been upgraded from Gorilla Glass to durable Sapphire Crystal glass, while the bezel transitions from stainless steel to titanium. Internally, the watch houses a newly upgraded optical heart rate sensor, a faster Apollo 510 processor, and expanded battery efficiency. GPS endurance climbs to 38 hours in dual-frequency mode or 45 hours in single-frequency mode, while daily smartwatch battery life extends from 9 days to 12 days.

Internal storage has also been doubled from 32GB to 64GB, paving the way for offline music playback. The device now supports local playback of MP3 audio files paired via Bluetooth headphones, though it lacks integration with mainstream third-party offline music streaming services. Additionally, the watch permits up to three concurrent SuuntoPlus apps within a single active profile, a slight increase from previous limitations. The official case size increases marginally from 45mm to 46mm, yet the overall weight decreases from 60 grams to 56 grams.

Despite these hardware enhancements, the retail pricing has undergone a dramatic shift, jumping from $349 USD for the original Race S up to $599 USD for the Race 3S, alongside a European pricing shift from 349 EUR to 499 EUR. Industry analysts note that while near-field communication may appear on specification sheets for specific regional variants like China, contactless payment integration is absent in other markets. Software enhancements mirror features previously rolled out to the Suunto Race 2, including a new Tide Widget, expanded map labels highlighting road names, water bodies, and mountain peaks, and Ascent as a dedicated exercise target. Suunto has also confirmed that a new Race Planner feature will arrive via a software update later in the year, designed to assist athletes with environmental and weather adaptation strategies. The device launches in three distinct color options: purple, white, and black.

In the Box and Unboxing Experience

The retail packaging for the Suunto Race 3S follows the clean, minimalist design language established by the company’s recent wearable releases. Opening the box reveals a straightforward collection of components, including the watch pod separated from the strap, a braided charging cable, and essential product documentation.

The magnetic charging cable represents a welcome improvement over the hardware included with earlier models, offering a more secure and reliable connection that prevents the misalignment issues reported by users of previous generations. Setting up the device requires a brief assembly process to attach the standard straps to the watch pod, after which the system is ready for initial configuration and pairing.

The Basics and Daily Usability

The user interface of the Suunto Race 3S relies on a traditional three-button layout combined with a responsive touchscreen, allowing users to navigate menus through touch inputs or physical controls depending on preference. The upper right button opens the workout menu, the central Digital Crown enables scrolling and quick access to pinned widgets during daily smartwatch use, and the bottom button functions as a back and escape control.

The 2,000-nit touchscreen delivers high visibility in bright outdoor environments, performing reliably under intense sunlight. However, industry observers have noted that competing devices released in the same window often utilize panels reaching 3,000 to 3,500 nits while maintaining lower price points. While screen legibility remains clear under various lighting conditions, power-saving algorithms tend to dim the display aggressively shortly after a wrist raise, a behavior that could benefit from refinement. Additionally, unlike the similarly priced Suunto Vertical 2, the Race 3S omits a physical LED flashlight, relying entirely on a screen-based illumination feature.

Daily tracking features such as step counting, sleep monitoring, and heart rate variability metrics function consistently, aligning closely with benchmark wearables. Sleep tracking accurately captures sleep onset and wake times within a narrow margin of error. The internal storage expansion to 64GB accommodates local music files for users who prefer transferring MP3 tracks via a direct computer connection, though the lack of streaming service integration limits its appeal for mainstream audiences accustomed to cloud-based audio platforms. Smartphone notifications deliver standard text and emoji displays without advanced interactive capabilities.

Sports Usage, Mapping, and Navigation

Accessing sports profiles on the Suunto Race 3S is streamlined through the workout panel, which quickly acquires GPS signals, heart rate locks, and external sensors such as cycling power meters or chest straps. Users can select from an extensive library of sport modes, load pre-planned navigation routes, and enable up to three concurrent SuuntoPlus applications or structured training guides.

Map management relies on Wi-Fi downloads through the companion smartphone application, allowing users to sync regional topographical data directly to the device. While map rotation is instantaneous and smooth, zooming in and out frequently triggers temporary black square tiles while detailed cartographic data renders. Navigation prompts provide clear acoustic chimes and visual turn-by-turn notifications, ensuring athletes stay on track during complex trail runs or unfamiliar urban routes. Post-workout summaries display comprehensive performance metrics directly on the wrist before automatically syncing data to third-party platforms like Strava and TrainingPeaks.

Accuracy of Heart Rate and GPS Tracking

The newly engineered optical heart rate sensor integrated into the Suunto Race 3S—featuring multiple LEDs and photodetectors behind curved glass—delivers significant performance improvements over its predecessor. Field testing across rolling hills, technical trail runs, and gravel cycling sessions demonstrates high fidelity when compared against traditional chest strap monitors, maintaining stability even during rapid transitions in elevation and intense physical exertion.

GNSS and GPS tracking performance remains dependable across open environments, maintaining tight alignment with known mapping paths and matching the positional accuracy of competing flagship wearables. While dense urban environments surrounded by tall buildings present inevitable multipath interference challenges for nearly all modern GPS receivers, the device recovers quickly once clear sightlines to the satellite constellations are restored. Elevation tracking, supported by the built-in barometric altimeter, records accurate ascent and descent profiles during extended mountain excursions. Battery endurance testing under continuous dual-frequency GPS usage with navigation enabled yields impressive operational longevity, aligning closely with official manufacturer specifications while providing granular power consumption data within recorded activity files.

The Suunto AI Coach Subscription Service

Suunto has introduced the Suunto AI Coach subscription service, designed to leverage historical and real-time training data to provide advanced race planning insights and personalized athletic guidance. While the feature launches alongside the Suunto Race 3S, it operates primarily within the mobile application environment rather than running locally on the watch hardware.

New purchasers of the Suunto Race 3S receive a temporary introductory trial period, though long-term subscription pricing details have not yet been finalized by the company. This approach has drawn scrutiny from consumers and reviewers wary of recurring software fees. Nevertheless, Suunto has also announced the development of a complimentary framework for all platform users, ensuring that baseline analytical tools remain accessible without a paid subscription.

Wrap-Up and Market Position

The launch of the Suunto Race 3S places the brand in a challenging market position. Despite a history of delivering well-received sports watches and consistent software updates, the substantial price increase separates the device from the competitive value proposition established by earlier iterations. While the hardware incorporates welcome upgrades—including a titanium bezel, sapphire crystal lens, expanded storage, and a much-improved optical heart rate sensor—the pricing structure places it in direct competition with heavily featured alternatives that offer higher display brightness, onboard flashlights, and native streaming audio support at lower price points. For dedicated athletes invested in the Suunto ecosystem, the Race 3S offers refined performance and reliable tracking, but its overall value proposition remains a subject of ongoing debate within the endurance sports community.
