Apple Watch Series 11: what changed

• Blood pressure trends: not a cuff replacement, but it flags rising patterns over weeks — the kind of early warning that matters. FDA-cleared.
• 20% better battery: a genuine 28-hour day including sleep tracking, up from "charge it during dinner."
• Faster S11 chip: apps launch noticeably quicker; same always-on display.

Apple Watch Ultra 3: who it's for

• Satellite emergency SOS: send help messages off-grid — a real feature for hikers, not a marketing checkbox.
• 42-hour battery: a weekend trip without the charger.
• 3,000-nit display: readable in direct mountain sun.
