Apple Watch Ultra 3 — Satellite comms, S10 chip, up to 42‑hour battery
Apple’s new Watch Ultra 3 brings several upgrades focused on connectivity and endurance. Key highlights:
- Satellite communications — Emergency SOS via satellite, plus Messages and Find My via satellite. Apple includes two years of satellite service; Messages and Find My via satellite require an active cellular plan (Emergency SOS via satellite works without a paid watch plan for emergency use).
- S10 chip — New 64‑bit S10 processor for improved performance and efficiency.
- Display & battery — Larger LTPO3 wide‑angle OLED with thinner bezels; Apple claims up to 42 hours of battery life (longer in low‑power modes).
- Connectivity & health — 5G support, dual‑frequency GPS, hypertension notifications, Sleep Score and other health features introduced with Series 11, plus watchOS 26 features.
- Availability — Pre-orders start September 15, in stores on September 19. See Apple’s official product page for full specs and regional availability.
How satellite works on the Ultra 3
You can launch satellite features from Control Center or a watch complication. Emergency SOS via satellite walks you through multiple‑choice questions for rescuers and guides you to point your wrist at the sky to establish a link; Messages and Find My let you send short status updates or share location off‑grid. Apple provides a demo mode so users can practice before an emergency.
Notes & comparison
Apple’s approach mirrors the iPhone’s satellite tools and includes a two‑year free period for satellite service. Google’s Pixel Watch 4 also includes a two‑year Satellite SOS option but currently limits availability by model and region. Full country lists and post‑trial pricing should be checked on the official product page.
