Expected fall 2026
The Ultra 4 is strongly rumoured for September 2026 alongside Series 12 and iPhone 18. Multiple supply-chain sources and analysts in early 2026 point to a ~15% thinner titanium case, Touch ID integrated into the side button or crown, a new T8320 processor, doubled sensor components for future health features, and an OLED display retained. Pricing is expected to remain around $799–$899.
The Apple Watch Ultra 3, released September 2025, is Apple's most rugged and capable smartwatch — built for athletes, divers, and mountaineers. It delivers 42 hours of battery life (72h in low power mode), dual-frequency L1+L5 GPS, a 3000-nit display readable in direct sunlight, satellite emergency SOS, and hypertension detection. Starting at $799.
The Ultra 3 nearly doubles the Series 11 battery life, and satellite emergency SOS works even without cellular or WiFi coverage.
More precise GPS tracking in urban canyons and dense forests — critical for trail running, mountaineering, and triathlon.
The 49mm titanium case and 3000-nit display make this watch usable in full direct sunlight and water depths up to 100m (EN13319 certified for diving).
Serious athletes, trail runners, triathletes, and outdoor adventurers who need the most durable, most accurate GPS watch Apple makes. Also for iPhone users who simply want the best Apple Watch regardless of sport, and value the extra battery life over the Series 11.
Ultra 4 is expected in fall 2026. With a 727-day prior cycle, there's a strong case for waiting if you're buying in spring 2026. If you need a watch now, the Ultra 3 is outstanding — just expect it to drop in price when Ultra 4 arrives.
Ultra 3 wins for ecosystem integration, display quality, and cellular. Garmin Fenix 8 wins on battery life (18 days vs 1.75 days) and sports analytics depth. For pure outdoor endurance sports, Garmin; for everything else plus sport, Apple.
For most recreational and semi-elite runners, yes. Serious ultramarathon runners or those doing multi-day races where charging is impossible will still prefer a Garmin or COROS with week-long GPS battery.
Yes — Apple Watch Ultra 3 supports Emergency SOS via satellite when no mobile signal is available. It also supports satellite-assisted location sharing via Find My.
Yes — it has 100m water resistance, EN 13319 dive certification to 40m, a built-in depth gauge, and a temperature sensor. It is one of the only smartwatches certified for recreational scuba diving.
