Suunto’s 56g Race 3S combines a bright AMOLED display, dual-band GPS, offline maps and extended battery life, but its $599 price comes with some notable compromises.
Suunto has pushed its Race line further towards the premium end of the sports-watch market with the Race 3S, a lighter 46mm model aimed at runners, hikers and endurance athletes who want a compact device without giving up flagship-class hardware. The watch weighs 56g with the strap attached and pairs a titanium bezel with sapphire glass, while Suunto says it is water-resistant to 5 ATM and available in Orchid, Feather and Black finishes. According to Suunto and early hands-on reviews, the design is intended to offer durability in a form factor that is easier to wear for long sessions and everyday use.
The display is one of the clearest upgrades. Suunto’s product information lists a 1.32-inch AMOLED panel with 466 x 466 resolution, 2,000 nits peak brightness and adaptive refresh, while T3 described it as much brighter than the earlier Race S. That matters in practical use: maps, pace data and heart-rate metrics should remain readable in direct sunlight, on shaded trails and in other difficult lighting conditions. The company also says the watch includes dual-band L1 and L5 positioning and free global offline maps, both of which are central to its outdoor positioning.
Hardware changes go beyond the screen. Suunto says the Race 3S now has 64GB of storage, up from 32GB, along with longer battery life and a new silicon-carbon battery design. The company quotes up to 38 hours in dual-band GPS mode and up to 12 days in daily use, while T3 reported a figure of 45 hours in dual-band GPS mode on launch coverage, suggesting battery life may vary depending on settings and test conditions. Tom’s Guide also noted an improved optical heart-rate sensor, saying it was more accurate than previous Suunto versions and generally matched a chest strap closely in testing, though it could still lag briefly at the start of colder outdoor runs.
For training, Suunto is leaning on a mix of navigation and coaching tools rather than consumer smart features. Tom’s Guide said the watch supports a large range of sport modes, customisable training screens, SuuntoPlus extras and a new AI Coach service, with buyers given a limited free trial. The same review found GPS accuracy strong in multi-band mode and said the watch tracked pace and distance in line with leading rivals. At the same time, it highlighted some practical limits: music support is restricted to locally stored files rather than streaming services, routes are not generated on the watch itself, and the interface still asks users to learn a fairly technical set of training metrics.
That leaves the Race 3S as a focused but expensive proposition. Suunto has set the price at $599, placing it against rivals such as Garmin and Coros models that may offer similar training tools, and in some cases more flexible navigation or lower pricing. For athletes who value compact dimensions, a bright display, offline maps and a rugged build, it is a serious option. For buyers who want streaming music, on-device route creation or the broadest feature set for the money, the compromises are harder to ignore.
