Suunto Race 3S Debuts With Titanium Build and AI Coach, but Stirs Debate Over Steep Price Increase

Suunto has officially announced its latest wearable, the Suunto Race 3S, introducing a compact small-form-factor watch that arrives alongside a significant price increase and a brand-new subscription service. Running concurrently with the hardware release, the company has launched the Suunto AI Coach, a new subscription platform designed to funnel advanced Suunto App features and personalized insights to users. Having spent the past few weeks putting the Suunto Race 3S through intensive daily usage across various endurance and outdoor activities, the central question remains whether Suunto can successfully justify the dramatic price jump for what is primarily an incremental hardware refresh.

The new Suunto Race 3S brings several notable improvements to the table, including a significantly brighter display, expanded internal storage, and several software feature updates that bypassed the existing Race S model earlier in the summer. While the updates represent a welcome refinement rather than a complete reinvention of the product line, the device does sport a more premium material profile. Most notably, Suunto has shifted from the stainless steel bezel used on its predecessor to a more durable and lightweight titanium bezel, paired with a sapphire crystal lens cover to enhance overall ruggedness.

What’s New in the Suunto Race 3S

The Suunto Race 3S arrives as an evolutionary upgrade to the existing Suunto Race S, skipping any intermediate "2S" designation while curiously leaving a larger standard "Race 3" companion out of the initial lineup. When questioned about the absence of a larger flagship model, company representatives offered no official comment. Although the original Race S continued to receive firmware updates through April, the Race 3S focuses on a specific suite of hardware and software enhancements.

On the hardware front, the upgrades are substantial on paper. Peak display brightness has been doubled from 1,000 nits to 2,000 nits, while the lens cover has been upgraded from Gorilla Glass to sapphire crystal. The bezel material shifts to titanium, complemented by an updated optical heart rate sensor and a faster Apollo 510 processor. Battery performance has also seen improvements, with dual-frequency GPS tracking time increasing from 30 to 38 hours, single-frequency GPS lasting up to 45 hours, and daily smartwatch mode extending from 9 days to 12 days. Internal storage has doubled from 32GB to 64GB, enabling offline music playback restricted to MP3 files via cable transfer, as streaming service integration remains absent. Additionally, the device supports up to three concurrent SuuntoPlus apps in a single profile, a slight increase from the previous limit of two.

The official case size increases marginally from 45mm to 46mm, yet the overall weight decreases from 60 grams to 56 grams. However, the most striking change is the retail pricing structure. The watch launches at $599 USD and 499 EUR, representing a substantial price increase compared to the $349 USD and 349 EUR launch price of the original Suunto Race S. While some international spec sheets list NFC capability, that feature is strictly limited to the Chinese market, with no contactless payment options available globally due to legacy industry restrictions.

Software updates bring over features previously rolled out to the Suunto Race 2 over the summer, including a new Tide Widget, expanded map labels displaying road names, water bodies, and mountain peaks, and the addition of Ascent as an exercise target. Furthermore, Suunto has confirmed that a new Race Planner feature will arrive later in the year, designed to incorporate historical training weather and environmental factors into race preparation without requiring the separate AI Coach subscription. The watch is initially available in three color options: purple, white, and black.

In the Box and Basic Operation

The unboxing experience follows Suunto’s established retail presentation. Inside the box, users find the watch pod separated from the band, a braided magnetic charging cable, and standard documentation. The magnetic charging cable marks a noticeable improvement over the older connector used with the initial Suunto S model, which frequently suffered from alignment issues. Assembly is straightforward, requiring users to attach the standard straps to the watch body before initial setup.

The device relies on a familiar three-button layout combined with a responsive touchscreen, allowing users to navigate the interface through touch inputs or physical controls. The upper right button opens the sport menu, the middle digital crown scrolls through lists and pinned widgets during daily smartwatch usage, and the bottom button functions as a back and escape control. The left side of the case remains entirely clean of buttons.

The 2,000-nit touchscreen remains exceptionally clear and legible under bright sunlight, performing admirably in outdoor environments. Despite its high visibility, the display panel sits slightly behind the curve compared to competing models released in late 2026, which frequently utilize 3,000-nit to 3,500-nit panels at a lower price point. Power-saving algorithms also tend to act aggressively, dimming the panel rapidly within seconds of a wrist raise. Furthermore, unlike the similarly priced Suunto Vertical 2, the Race 3S lacks a physical LED flashlight, relying instead on a less effective screen-based illumination mode.

Widget navigation reveals customizable data screens for daily metrics, though minor interface lag remains noticeable during menu scrolling despite the inclusion of the newer processor. Daily health monitoring features, including sleep tracking and heart rate variability status, align closely with industry norms, providing consistent readings that match comparative wearables within acceptable margins. Internal storage expands to 64GB, though the primary justification for the massive capacity centers on offline music storage rather than map data, given the compact size of Suunto’s highly optimized topographical maps. Music management remains limited to manual MP3 file transfers via USB cable, as native offline streaming support from major platforms is unavailable.

Sports Usage and Mapping

Accessing workout modes is accomplished through the upper right button, which launches the exercise panel to search for GPS locks, heart rate data, and external sensors. Users can easily toggle between an extensive library of sport profiles, load pre-planned navigation routes, and enable up to three concurrent SuuntoPlus apps. Exercise settings allow for customized display metrics, including the newly added Ascent training target.

Offline maps are easily downloaded via Wi-Fi through the companion application by selecting specific regional areas. However, the ecosystem continues to present minor workflow frustrations, particularly regarding app-to-watch synchronization. Initiating configuration changes frequently triggers an automatic sync that restricts manual adjustments until completion, with no straightforward option to cancel an active transfer. Customizing data fields also requires creating entirely new user profiles rather than editing default sport modes, a rigid structure that contrasts with modern competitors.

During active outdoor sessions, navigation alerts provide clear audio and visual notifications for upcoming turns and off-route deviations. Map rendering performance presents a mixed experience. While map rotation is instantaneous without missing tiles, zooming in or out consistently triggers temporary black square tiles while detailed cartography renders, creating a slightly unfinished visual appearance during fast-paced movement. Elevation profiles and climb tracking function reliably throughout workouts, and completed sessions sync automatically to third-party platforms like Strava and TrainingPeaks.

Accuracy of Heart Rate and GPS

The introduction of the new optical heart rate sensor—featuring six LEDs and four photodetectors beneath curved glass—delivers a substantial performance improvement over previous iterations. Across rigorous testing scenarios involving rolling hills, steep descents, and technical trail runs, the sensor maintains strong correlation against chest strap monitors, handling rapid cardiovascular transitions and high-intensity efforts without significant artifacts or lag. Gravel cycling sessions characterized by frequent stops and rough terrain yield similarly stable and accurate optical tracking results.

GNSS and GPS performance remains dependable across standard outdoor environments. Open-sky running and trail sessions demonstrate tight track adherence, with positional variances rarely exceeding a few meters among competing multi-band devices. Dense urban environments surrounded by tall buildings present typical challenges for all wearable manufacturers, leading to minor tracking drift as signals reflect off architectural facades, but performance normalizes immediately upon returning to open areas. Elevation tracking using the barometric altimeter remains stable, while battery performance closely mirrors official specifications, delivering multiple days of regular use with daily GPS tracking enabled.

Suunto AI Coach Subscription

Alongside the hardware release, Suunto introduced the Suunto AI Coach subscription service, which leverages historical training data and current metrics to provide advanced race planning and personalized insights. While initial buyers of the Suunto Race 3S receive a three-month complimentary trial, Suunto has not yet disclosed permanent subscription pricing once the promotional period concludes. The lack of transparent pricing has drawn scrutiny from consumers wary of open-ended software commitments. Despite these concerns, Suunto also announced a separate, free Suunto MCP platform intended to provide baseline digital enhancements without ongoing fees, aligning with broader industry trends toward hybrid freemium models.

Wrap-Up

The Suunto Race 3S arrives following a period of strong product momentum for the brand, yet its market positioning feels complicated. At a retail price of $599 USD and 499 EUR, the device represents a steep price increase over its predecessor without a corresponding leap in advanced hardware capabilities. While the titanium bezel, brighter display, improved optical heart rate sensor, and expanded storage are welcome additions, the lack of modern conveniences like streaming music integration, physical flashlights, and more competitive display panel technology makes the premium price point difficult to justify against less expensive market rivals offering comparable or superior specifications.
