Suunto Race 3S Review — $599 Titanium Trail Watch?! 38 Hours GPS + AI Coach

Suunto just made its smallest watch its most expensive one. The Race 3S is a 46mm titanium trail watch with a sapphire crystal, a 2,000-nit AMOLED screen, free global offline maps, and a brand-new AI Coach — all for $599. That is $250 more than the Race S it replaces. But there are no contactless payments, no LED flashlight, no speaker, and the AI Coach becomes a paid service after three free months — with no price published yet. So is it worth it? In this full review: the $599 price vs the $349 Race S and the $449 COROS Pace 4 Pro, the titanium + sapphire design, the new heart rate sensor DC Rainmaker calls really good, free offline maps, Suunto AI Coach, the 38-hour GPS battery claim (and the honest real-world caveat), and the final verdict — who should buy it, and who should take the Race 2 or the Run 2 instead.
