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

Suunto has officially announced the launch of its newest small-form-factor wearable, the Suunto Race 3S. Alongside the hardware release, the company has introduced a new subscription service called Suunto AI Coach, which serves as a new hub for advanced application features. Following several weeks of extensive testing across diverse athletic activities, tech analysts and reviewers are examining how the new device operates and whether Suunto can successfully justify its significant price increase compared to previous iterations.

The new Suunto Race 3S arrives with a brighter display, expanded storage capacity, and several software updates that were notably omitted from the existing Race S model earlier in the year. While these modifications do not represent a sweeping reinvention of the product line, the improvements are welcomed by users. Hardware modifications include a shift from a stainless steel bezel to a more premium titanium bezel, paired with an upgraded sapphire crystal glass lens cover.

When evaluating the hardware alterations against the original Suunto Race S, which continued to receive firmware updates until this past spring, several distinct changes emerge. The peak display brightness has been upgraded from 1,000 nits to 2,000 nits. The lens cover material has transitioned from Gorilla Glass to Sapphire Crystal, and the bezel has shifted from stainless steel to titanium. Internally, the watch incorporates an upgraded optical heart rate sensor, a faster Apollo 510 processor, and expanded internal storage moving from 32GB to 64GB.

Battery performance has also seen incremental gains. GPS tracking time in dual-frequency mode has increased from 30 hours to 38 hours, while single-frequency mode yields 45 hours. Daily smartwatch battery life has risen from 9 days to 12 days. The device now includes support for offline music playback utilizing MP3 files transferred via cable, though it lacks modern streaming service integrations. Additionally, the number of concurrent SuuntoPlus apps allowed in a single profile has expanded from two to three, and the official case size has shifted slightly from 45mm to 46mm while decreasing in weight from 60 grams to 56 grams.

The most contentious change, however, is the retail price. The Suunto Race 3S launches at $599 USD and 499 EUR, a sharp increase from the $349 USD and 349 EUR price point of the original Suunto Race S. This dramatic shift places the device in a highly competitive bracket, particularly when compared against alternative sports watches launched during the same period.

Software updates integrated into the Race 3S include the addition of a Tide Widget, expanded map labels displaying road names, water features, and mountain peaks, and the inclusion of Ascent as a dedicated exercise target. Furthermore, Suunto has confirmed that a new Race Planner feature will arrive later in the year via a software update, focusing on comprehensive race day preparation, including weather pattern analysis. The watch is available in three color options: purple, white, and black.

Unboxing the Suunto Race 3S reveals a familiar packaging design consistent with recent Suunto releases. The box includes the watch pod, a standard band strap, paper documentation, and a braided magnetic charging cable that offers improved connection reliability compared to the magnetic mechanism found on the original S model. Attaching the strap to the watch pod requires a brief assembly process before the device is ready for daily use.

Navigating the user interface relies on a three-button layout combined with a responsive touchscreen. The upper right button opens the sport menu, the middle digital crown scrolls through screens and accesses pinned widgets, and the bottom button serves as a back and escape function. The left side of the watch case remains clean of buttons.

The 2,000-nit touchscreen performs adequately in bright outdoor conditions, though power-saving algorithms tend to dim the panel quickly after a wrist gesture. Notably, unlike the similarly priced Suunto Vertical 2, the Race 3S lacks a physical LED flashlight, relying instead on a screen-based illumination feature. Widget navigation reveals a customizable suite of quick-access data fields, including standard metrics for steps, sleep, and weather, alongside the newly introduced tide tracker.

Sleep tracking metrics generally align closely with competing wearables regarding sleep duration and wake times, while heart rate-driven calculations benefit significantly from the newly integrated optical sensor located on the bottom case of the watch. The expanded 64GB internal storage is designed primarily to accommodate offline audio files. Because Suunto watches do not support offline streaming services like Spotify due to industry limitations, users must manually transfer owned MP3 files via USB cable and pair a set of Bluetooth headphones to listen to music during workouts. Basic smartphone notifications deliver standard text and emoji alerts.

Accessing sports and navigation features is streamlined through the upper right button, which opens the workout panel to search for GPS signals, heart rate locks, and paired external sensors. Users can select from a wide array of sport profiles, load navigation routes, and enable up to three concurrent SuuntoPlus apps. While mapping data is not pre-loaded on the device, regional maps can be easily downloaded over Wi-Fi through the companion smartphone application.

During sports usage, the watch provides reliable turn-by-turn navigation alerts with audible chimes and on-screen prompts. Map rendering performance presents a mixed experience; while map rotation is instantaneous and smooth, zooming in or out consistently triggers temporary black square tiles while the display renders the detailed map graphics. Post-workout summaries are displayed directly on the watch face and automatically synchronized with the Suunto mobile app, which in turn pushes data to third-party platforms like Strava and TrainingPeaks.

The newly designed optical heart rate sensor, featuring six LEDs and four photodetectors beneath curved sensor glass, demonstrates a marked improvement over previous generations. Field testing across varied terrain, including steep descents, rolling hills, and technical trail runs with frequent changes in elevation and pace, shows that the optical sensor maintains strong correlation and accuracy when compared against chest strap monitors.

GPS tracking performance using multiband and dual-frequency settings remains consistently solid across open outdoor environments. While urban environments featuring dense high-rise buildings present typical multi-path interference challenges for all modern wearable devices—leading to minor trajectory drift and corner-cutting—the watch performs reliably once clear of architectural obstructions. Elevation tracking similarly proves stable, matching expected barometric profiles across extended training sessions.

Alongside the hardware release, Suunto has introduced the Suunto AI Coach subscription service, which analyzes historical and current training data to provide advanced race planning and personalized insights. While the new watch includes a three-month complimentary trial of the service, Suunto has not yet disclosed the permanent pricing structure that will take effect once the trial period concludes. This lack of upfront pricing transparency has drawn scrutiny from users wary of subscription models. Additionally, Suunto announced a free analytics initiative known as Suunto MCP, which will remain accessible to all platform users without a recurring fee.

Evaluating the overall market position of the Suunto Race 3S reveals a challenging paradox. Following a prolonged period of well-received product releases and continuous software support, the Race 3S arrives with a pronounced price premium that surpasses a seventy percent increase compared to its predecessor. Although the device features a brighter display, expanded storage, and a vastly improved optical heart rate sensor, it lacks certain physical hardware attributes—such as a dedicated LED flashlight, integrated microphone and speaker hardware, or native streaming music integration—that are increasingly common among competing products available at comparable or lower price points.

Ultimately, while the Suunto Race 3S delivers reliable athletic tracking, robust navigation tools, and significantly enhanced optical heart rate accuracy, its high retail price point places it in a fiercely contested market sector where value and feature parity are heavily scrutinized by consumers.
