2026 Sport Watch Predictions: Fenix 9, Apple Watch 12, Vertix 4

The 2026 wearable lineup is shaping up to be the most competitive in years. Garmin, Apple, Coros, Polar, and Samsung all have major releases expected, and the rumored specs suggest real performance upgrades rather than cosmetic refreshes.

Garmin Fenix 9 is the most anticipated. The Fenix 8 already pushed solar battery life past 100 hours in GPS mode, and the 9 is expected to go further with improved multi-band accuracy and a potential recovery-tracking subscription tier that would put it directly against Whoop. That last part is speculative, but Garmin has the sensor stack to make it real.

Apple Watch 12 is rumored to include touch-based unlock, which matters less for endurance athletes than the persistent GPS accuracy issues that still haunt the Series 10. If Apple fixes the HR drift problem during high-intensity intervals, it becomes a genuine training tool. Right now, it still trails Polar Vantage V3 and Coros Pace 3 on raw training data reliability.

Coros Vertix 4 should build on the Vertix 3's already impressive battery life, which clocks around 140 hours in GPS mode. Polar Vantage V4 paired with a rebuilt FLOW platform would finally give Polar athletes the ecosystem depth that Garmin Connect users have had for a decade. Samsung Watch Ultra redesign rounds out the field, but it remains a fitness watch trying to be a sport watch.

Solid year ahead on paper. The real test is always in execution.
