Apple Watch Ultra 4 Will Double Its Sensor Count and Feature a 'Quiet Redesign,' Reports Say

The Apple Watch Ultra 4 is shaping up to be the biggest sensor upgrade in Apple Watch history, with multiple reports from late August confirming the rugged model will significantly expand its health-tracking capabilities when it debuts at Apple's September 9 event.

Key Upgrades

• Doubled sensor count: The Ultra 4 will pack significantly more health sensors than the Ultra 3, focused on cardiovascular and metabolic monitoring
• Blood pressure monitoring: Wrist-based blood pressure trend reporting is the headline feature, building on the hypertension alerts Apple introduced in watchOS 26. Full on-wrist readings remain uncertain, but trend analysis over 30 days is expected
• New chip: An internal "Watch8" family processor (T8320) — the first major chip upgrade since the S10 generation debuted in 2023
• Display: Up to 2,000 nits peak brightness

Touch ID: Reportedly Cut

Despite persistent rumors, multiple sources now say Apple has decided against integrating Touch ID into the digital crown or action button. Design constraints and battery life concerns reportedly took precedence over the added security feature.

Pricing and Availability

The Ultra 4 is expected to hold at $799, matching the Ultra 3's launch price. Pre-orders should open September 12, with in-store availability September 19.
