Hands-on with the New Apple Watch Series 12 and Apple Watch Ultra 4: What’s New, What’s Better, and What It Costs
Apple unveiled the Apple Watch Series 12 and Apple Watch Ultra 4 at its September 9, 2026 event, alongside the company’s first foldable iPhone. The new wearables bring faster processors, longer battery life, and refined health sensors—but the Ultra 4 is expected to command a higher price than its predecessor. Here’s what we know from early hands-on reports and preorder data.
Why This Matters
For the estimated 200 million+ active Apple Watch users, this refresh determines whether to upgrade, hold, or switch platforms. For the broader wearable industry, Apple’s annual cadence sets the benchmark for health tracking, battery efficiency, and rugged design. The Series 12 and Ultra 4 also arrive as Apple pushes deeper into AI-driven health insights—a trend that could reshape how consumers use wearables for proactive wellness, not just passive tracking.
The September 9, 2026 Launch: Key Facts
Apple held its annual hardware event on September 9, 2026, with new CEO John Ternus making his debut on stage. The event featured the first foldable iPhone (dubbed the “iPhone Duo” in some reports) and the iPhone 18 Pro, but the Apple Watch Series 12 and Ultra 4 were the wearable highlights.
Preorder deals went live immediately after the event, with major carriers and retailers offering trade-in bonuses and bundle discounts. According to CNET’s deal tracking, the best preorder offers include up to $150 off with qualifying trade-ins and free Apple Watch bands with select carriers.
Series 12 vs. Ultra 4: Specifications and Early Impressions
Early hands-on reports from The Verge and CNET highlight two distinct philosophies: the Series 12 as the everyday health companion, and the Ultra 4 as the extreme-environment powerhouse. Here’s how they compare based on confirmed specs and first impressions:
| Feature | Apple Watch Series 12 | Apple Watch Ultra 4 |
|---|---|---|
| Processor | New S-series chip (faster neural engine) | Same S-series chip, tuned for sustained performance |
| Display | Standard brightness, always-on | Brighter (up to 3,000 nits), flat sapphire crystal |
| Battery | All-day (up to 18–20 hours) | Up to 60 hours in normal mode, 100+ in low-power |
| Case Material | Aluminum, stainless steel, titanium | Titanium only (grade 5) |
| Health Sensors | ECG, blood oxygen, temperature | All Series 12 sensors + depth gauge, dual-frequency GPS |
| Price (starting) | $399–$429 (est.) | $799–$849 (up from $799) |
| Target User | Daily health, fitness, notifications | Athletes, divers, hikers, extreme sports |
Hands-on notes from early reviewers:
- Series 12: The new processor makes Siri responses noticeably faster, and the always-on display is easier to read in direct sunlight. The temperature sensor now provides nightly baseline reports with less drift.
- Ultra 4: The rugged build feels identical in weight to the Ultra 3, but the battery life improvement is the standout—reviewers report 2.5 days of heavy use without charging. The new depth gauge app now supports recreational dive profiles, not just depth logging.
Battery and Processing Power: The Ultra 4’s Big Leap
One of the most anticipated upgrades was the Ultra 4’s battery. CNET’s pre-launch analysis suggested the Ultra 4 could get a “back-to-back refresh with more processing power and battery, but potentially at a higher price.” That prediction held: the Ultra 4 starts at $849, a $50 increase over the Ultra 3.
The processing upgrade is shared across both models—a new chip with a faster neural engine that enables on-device AI for workout form analysis and sleep apnea detection. For Series 12 users, this means the same health features as the Ultra 4, minus the extreme-environment hardware.
Preorder Deals: What’s Available Right Now
If you’re planning to buy, the preorder window is the best time to save. According to CNET’s live deal tracker (published September 9, 2026), here are the standout offers:

FAQ: Common Questions About the Series 12 and Ultra 4
Q: When will the Apple Watch Series 12 and Ultra 4 ship?
A: Preorders opened September 9, 2026. Most models ship by September 18, with Ultra 4 configurations potentially delayed to late September due to higher demand.
Q: Is the Ultra 4 worth the $50 price increase over the Ultra 3?
A: If you need the extended battery (60+ hours) or the enhanced dive features, yes. If you use your Ultra mostly for workouts and notifications, the Series 12 offers the same processor at half the price.
Q: Does the Series 12 have the same health sensors as the Ultra 4?
A: Yes—both share the same core health suite (ECG, blood oxygen, temperature, sleep apnea detection). The Ultra 4 adds depth and water temperature sensors for diving.
Q: Will my old Apple Watch bands fit the Series 12 and Ultra 4?
A: The Series 12 keeps the same 45mm and 49mm case sizes, so existing bands fit. The Ultra 4 uses the same 49mm lug design as the Ultra 3.
Q: Should I upgrade from a Series 9 or Ultra 2?
A: The new processor and AI-driven health insights are the main reasons. If you don’t need on-device AI or the latest sleep apnea detection, your current watch remains supported.
The Road Ahead: What This Refresh Signals
The Series 12 and Ultra 4 aren’t revolutionary—they’re a consolidation of Apple’s wearable strategy. The processor upgrade is the real story, enabling AI features that will mature over the next year through watchOS updates. The Ultra 4’s price hike, while modest, signals that Apple sees the rugged smartwatch as a premium niche, not a mass-market product.
For buyers, the smart move is to decide based on battery needs and case durability, not specs alone. The Series 12 delivers 90% of the Ultra 4’s functionality at half the price. The Ultra 4 earns its premium for those who genuinely need multi-day battery and extreme-environment reliability.
As watchOS evolves, expect these devices to become more proactive—suggesting workouts, flagging health anomalies, and integrating deeper with Apple’s Health app. The hardware is here; the software is just getting started.
