Built for the Long Race

56 g, lighter than two energy gels. Flagship capability in a compact titanium build that stays comfortable through a long training day and a long race alike. Sapphire crystal glass, one of the hardest materials used in premium sports watches, holds off rock scrapes and branch strikes, so your route, data and navigation stay clear from start to finish.

Race-ready outdoor aesthetics

Exceptional scratch resistance

5 ATM water resistance

Confidence. Beyond the Trail

Precise Positioning
Dual-band L1 and L5 positioning holds steady where terrain and buildings scatter the signal. Deep forest, tight gorges, city streets — your line stays true and your track stays clean.

Free Global Offline Maps
Contour lines, place names, roads and water, downloaded to your wrist and free to keep. Complex terrain reads clearly at a glance, fully offline.

Charge Less. Run More.

Ultra-Long Battery Life

Suunto Race 3S runs on a high-density silicon-carbon battery that holds more energy in the same compact titanium body, so the longest days on the trail stay covered.
*Actual battery life may vary depending on settings, usage and operating conditions.

Up to 10 Days in Training Mode

Up to 12 Days in Daily Mode

Up to 45 Hours in Endurance Mode

Clarity When It Matters

Flagship Display

1.32" AMOLED, 2000 Nits Peak Brightness
466×466 resolution, with a 5Hz–60Hz adaptive refresh rate, 233% brighter than Race S.
Blazing sun, deep forest shade, dawn half-light — pace, route and heart rate all read in a single glance, so you keep running and keep your eyes on the trail.

Performance You. Can Count On
