Suunto Race 3S Review: A Feature-Packed Sports Watch for Smaller Wrists

Introduction to the Suunto Race 3S

The year has been exceptional for athletes and tech enthusiasts with slender wrists, as wearable manufacturers finally embrace compact form factors for their flagship devices. Following impressive smaller releases from Garmin, Apple, and Coros, Suunto has introduced the Suunto Race 3S. This device brings premium build materials and stellar battery life to a sleeker, smaller watch profile.

Building upon the legacy of previous iterations, the Race 3S arrives with notable upgrades including a vastly brighter display, enhanced battery management, and vastly improved optical heart rate accuracy. However, these premium features come with a significant price jump, making it a compelling yet challenging purchase compared to rival budget-friendly alternatives.

Price and Availability

Launched in October 2026, the Suunto Race 3S retails at $599 in the U.S. and £435 in the U.K. This represents a steep price increase over the original titanium Suunto Race S. With direct competitors like the Coros Pace 4 Pro and the Suunto Run 2 undercutting its price point, the Race 3S faces stiff competition in the mid-to-high-end sports watch market.

Design, Display, and Build Quality

The 'S' designation denotes a smaller, refined footprint designed specifically to provide a premium experience without the bulk traditionally associated with advanced sports wearables. The device features a gorgeous 1.32-inch AMOLED display boasting an impressive 2,000 nits of brightness—three times brighter than its predecessor—making it effortlessly readable under direct sunlight.

Encased in a durable titanium bezel and protected by sapphire crystal glass, the 46mm case maintains a light and slim profile at just 56g with its silicone strap. It features a responsive digital dial alongside two physical pushers, ensuring quick and seamless navigation through the user interface.

Sports Tracking and Training Analysis

Suunto offers an extensive array of preset sports modes directly on the device, complemented by fully customizable modes via the companion mobile app. The watch grants access to the SuuntoPlus Store for downloading additional sports applications and data metrics. While its training load analytics provide deep insights into athletic performance, they rely heavily on complex acronyms that might take beginners some time to master.

GPS and Heart Rate Accuracy

Equipped with multi-band GPS support, the Suunto Race 3S delivers exceptional location tracking, matching industry giants stride for stride. Furthermore, the overhauled optical heart rate sensor addresses previous generations' shortcomings, delivering robust tracking that closely mirrors dedicated chest-strap monitors across various high-intensity workouts and endurance runs.

Battery Life and Power Management

Despite housing a vibrant AMOLED screen, the Race 3S punches well above its weight class in longevity. Users can expect up to 12 days of standard smartwatch use or up to 38 hours of continuous multi-band GPS tracking. For heavy daily users with always-on displays enabled, the watch comfortably lasts between five and six days per charge.

Smart Features, Maps, and Navigation

While the Race 3S is fundamentally a sports watch rather than a daily smartwatch, it includes offline music storage for drag-and-drop audio files and 64GB of onboard memory for downloading comprehensive regional maps. The routing interface is snappy and clear, guiding athletes seamlessly through complex outdoor trails and alerting them to upcoming elevation changes.

The Verdict: Should You Buy It?

The Suunto Race 3S is undeniably an attractive, highly functional, and robust sports watch tailored for smaller wrists. Yet, its aggressive price hike puts it in direct competition with more affordable and feature-rich alternatives like the Coros Pace 4 Pro. If you are a dedicated Suunto fan looking for premium materials in a compact size, it is a worthy investment—though budget-conscious buyers may want to wait for seasonal sales.
