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

In a market often dominated by large, bulky timepieces, the Suunto Race 3S arrives as a refreshing option for those seeking a premium sports watch tailored to smaller wrists. Launched in late 2026, the Race 3S manages to pack high-end navigation and performance tracking into a refined 46mm chassis that remains comfortable for 24/7 wear.

Design and Display

The standout feature of the Race 3S is its design approach. It bridges the gap between rugged utility and aesthetic appeal. It boasts a stunning 2,000-nit AMOLED display, offering three times the brightness of its predecessor, the original Race S. Protected by sapphire crystal and housed in a titanium bezel, the build quality feels robust yet lightweight at just 56g with its silicone strap. While the user interface navigation via the digital dial can occasionally feel slightly sluggish, the overall performance is consistently snappy.

Sports Tracking and Accuracy

Suunto has made significant strides in accuracy with the Race 3S. Equipped with a new, highly responsive optical heart rate sensor, the watch provides data that closely mirrors results from dedicated chest straps, even during intense interval sessions or strength training. The inclusion of multi-band GPS tracking further cements its status as a reliable tool for serious athletes. It excels in remote training scenarios, and users can easily sync routes with elevation alerts via the updated Suunto app.

Training Analysis and Battery Life

For data-driven athletes, the watch provides deep insights into training load. While the heavy reliance on three-letter acronyms can be daunting for beginners, it serves as a powerful resource for those tracking long-term fitness. Battery performance is equally impressive for such a compact unit, lasting up to 12 days in standard watch mode and delivering an exceptional 38 hours of high-precision, multi-band GPS tracking.

The Verdict

Despite its technical prowess, the Suunto Race 3S faces a challenging market. With a significant price hike compared to previous models, it faces stiff competition from alternatives like the Coros Pace 4 Pro and the Suunto Run 2. While the Race 3S is undeniably a high-quality, feature-packed wearable that excels in GPS accuracy and build, budget-conscious buyers might find better value elsewhere. However, for those prioritizing a sleek, durable, and capable multisport watch for smaller wrists, it remains a top-tier contender.
