Quick summary: Apple Watch Ultra 4 is expected to launch in September 2026 alongside the iPhone 18 Pro. Key upgrades include a 15% thinner titanium case, possible Touch ID integration, an upgraded S11 chip, improved health sensors, and longer battery life — all at the same $799–$899 price point.
Apple’s Ultra line has always been the go-to smartwatch for serious athletes, outdoor adventurers, and anyone who wants the absolute best. Now, with the Apple Watch Ultra 4 on the horizon, the question everyone is asking is: how big of an upgrade is this actually going to be?
We’ve been tracking every leak, firmware discovery, and analyst report so you don’t have to. Here’s the most complete picture of what to expect from the Ultra 4 — and whether it’s worth waiting for.
Apple Watch Ultra 4 Release Date
Based on Apple’s consistent fall release schedule, the Apple Watch Ultra 4 is expected to be announced in early September 2026 at Apple’s annual fall event — most likely the first or second week of the month.
It will share the stage with the iPhone 18 Pro, iPhone 18 lineup, and possibly Apple’s long-rumored foldable iPhone. Pre-orders typically open the same day as the announcement, with deliveries arriving about 10 days later.
Likely Timeline
- Apple Event: First week of September 2026
- Pre-orders open: Same day as announcement
- Shipping begins: ~September 19–26, 2026
- In-store availability: Late September 2026
Apple Watch Ultra 4 Price
Good news for your wallet: Apple has held the Ultra line at the same price for three generations straight. The Apple Watch Ultra 4 is expected to start at $799, with some analysts suggesting it could go up to $899 depending on configuration.
No leaks currently point to a price increase, though rising component costs across the industry could push things slightly higher. For now, expect the same price as the Ultra 3.
Design: Finally Getting Thinner
This is where Ultra 4 gets interesting. After three generations with nearly identical dimensions, Apple is reportedly making the Ultra 4 about 15% thinner — a meaningful change for a watch that many people find bulky for everyday wear.
The core design DNA stays intact: square titanium case, flat display, Action Button, and the large Digital Crown. But the slimmer profile is expected to make it noticeably more comfortable for all-day and all-night wear without sacrificing durability.
- Titanium case retained (same rugged build)
- ~15% slimmer chassis than Ultra 3
- Flat OLED display — MicroLED delayed to a future model
- Action Button and Digital Crown design unchanged
- All existing Ultra bands (44/45/46/49mm) remain compatible
The MicroLED display many were hoping for has been pushed back. Apple’s supply chain reportedly couldn’t finalize MicroLED for 2026, so Ultra 4 sticks with the proven OLED-LTPO panel — still excellent at up to 3,000 nits brightness.
Unlike the Apple Watch Ultra 3 (which we reviewed in detail), the Ultra 4 brings a noticeably slimmer profile.

New Features to Expect
Touch ID — The Biggest New Addition?
Developers recently discovered references to “AppleMesa” inside leaked firmware for 2026 Apple Watch models. AppleMesa is Apple’s internal codename for Touch ID technology. If true, this would be the first time in Apple Watch’s 10-year history that the device includes fingerprint authentication.
Potential placement: the side button, the Digital Crown, or the Action Button. Touch ID would make unlocking the watch, authorizing Apple Pay, and accessing secure apps significantly faster and more reliable — especially useful when your hands are wet or you’re wearing gloves.
New S11 Chip
The Ultra 4 is expected to run on Apple’s new S11 chip, bringing improved processing efficiency and better battery management. Performance gains are expected to be incremental rather than transformative — but better efficiency means the hardware does more while draining less power.
Improved Battery Life
The Ultra 3 already offers impressive multi-day battery life. Ultra 4 is rumored to push that further, with some reports suggesting up to 72 hours of standard use — a meaningful jump for ultra-endurance athletes doing multi-day events.
Health & Fitness Upgrades
Apple is reportedly equipping the Ultra 4 with an upgraded 8-sensor array that promises more accurate readings across the board. Key improvements are expected in:
- Heart rate monitoring — more reliable during high-intensity workouts
- Blood oxygen (SpO2) — improved accuracy, especially at altitude
- Irregular heart rhythm detection — enhanced ECG capabilities
- Sleep tracking — better precision with the slimmer, more comfortable form factor
What’s NOT Coming to Ultra 4
Despite years of development, non-invasive blood glucose monitoring is not expected to arrive with the Ultra 4. Apple is still actively working on the technology, but 2026 does not appear to be the year it makes it to consumers. Don’t hold your breath for this one — at least not yet.
Apple Watch Ultra 4 vs Ultra 3: Is It Worth Upgrading?
| Feature | Ultra 3 (2025) | Ultra 4 (2026) |
|---|---|---|
| Design | Same as Ultra 2 | 15% thinner |
| Chip | S10 | S11 (new) |
| Touch ID | ❌ No | ✅ Possibly yes |
| Battery | ~60 hours | ~72 hours (rumored) |
| Health sensors | Standard array | 8-sensor upgrade |
| Blood glucose | ❌ No | ❌ Still no |
| Display | OLED, 3,000 nits | OLED (MicroLED delayed) |
| Price | $799 | $799–$899 |

Should You Wait for the Apple Watch Ultra 4?
If you own an Ultra 2 or Ultra 3: Probably not worth upgrading unless Touch ID gets confirmed — the changes are evolutionary rather than revolutionary. Your current watch will get watchOS 13 and remain fully capable.
If you’re buying your first Ultra or upgrading from an older model: Absolutely wait. September 2026 is just a few months away, and the Ultra 4 will be the best Apple Watch ever made at launch.
If you’re on a budget: The Ultra 3 price will likely drop significantly after Ultra 4 launches — that’s a great window to grab it.
If Apple Watch isn’t your style, the Galaxy Watch Ultra 2026 is worth considering as a strong alternative.
