Apple Watch Ultra 4 vs Ultra 3: Should You Wait or Buy Now in 2026?

The Apple Watch Ultra 4 is shaping up to be a major upgrade: leaked details reveal Touch ID, doubled health sensors, a thinner design, and potentially real blood pressure readings. Meanwhile, the Ultra 3 is discounted to $609— its deepest price cut yet. Should you buy the bird in hand, or wait five months for what's coming?
Ultra 3 Now
$609 on Amazon (was $799). Proven, available today, best rugged Apple Watch ever made.
Ultra 4 Coming
Expected September 2026. Touch ID, 2× sensors, thinner body, real BP readings.
Our Take
Buy Ultra 3 now if you need a watch. Wait only if Touch ID or blood pressure values are must-haves.
What Do We Know About Apple Watch Ultra 4?
Multiple leaks and analyst reports have painted a clear picture of what's coming. Here are the confirmed and high-confidence rumors:
Touch ID: Finally, No More Passcodes
References to "AppleMesa"in leaked developer software confirm Apple is building fingerprint authentication for Apple Watch. You'll likely unlock by touching the screen or digital crown — a genuinely useful improvement, especially with gloves or wet hands where the current passcode entry is painful.
Doubled Sensor Array
The Ultra 4 reportedly packs twice as many health sensors as the Ultra 3. Rather than adding entirely new measurement types, Apple is focused on making existing tracking significantly more accurate — heart rate, SpO2, and temperature sensors should all improve.
Real Blood Pressure Values
The Apple Watch Series 11 introduced basic hypertension alerts, but the Ultra 4 may deliver actual systolic/diastolic blood pressure readings. If this ships, it would be a massive leap for wrist-based health monitoring and a potential game-changer for the 100+ million Americans with hypertension.
Thinner, Lighter Design
Apple is reportedly slimming down the Ultra body while maintaining its rugged titanium build. The current Ultra 3 is 14.4mm thick — even a 1–2mm reduction would make a noticeable difference on the wrist.
What About Blood Glucose?
Not happening in 2026. Multiple analysts confirm Apple's non-invasive glucose monitoring technology isn't accurate enough to ship yet. This feature is likely several product cycles away. If glucose monitoring is your primary interest, the Oura Ring Gen 4 with its blood pressure estimation is the closest thing available in a wearable today.
How Good Is the Apple Watch Ultra 3 Deal Right Now?
Very good. The Ultra 3 is currently $609 on Amazon — down from its $799 retail price. That's a $190 discount (24% off) and its deepest price cut since launch. You get:
- Best-in-class GPS accuracy — dual-frequency GPS that's the gold standard for outdoor sports
- 36-hour battery life (72 hours in low power mode)
- 100m water resistance with depth gauge and water temperature
- Titanium case with sapphire crystal — the most durable Apple Watch
- Action Button for one-tap workout starts, waypoint marking, and more
- Siren for emergency situations, audible up to 180 meters away
Should You Buy Apple Watch Ultra 3 Now or Wait for Ultra 4?
Here's our decision framework:
Buy Ultra 3 now if:
- You need a rugged smartwatch today (training season, upcoming races, travel)
- The $609 deal is within your budget and you don't want to pay $799+ for Ultra 4 at launch
- The current health sensors meet your needs
- You're upgrading from Ultra 1 or a non-Ultra Apple Watch
Wait for Ultra 4 if:
- Touch ID is a must-have (you wear gloves, work with wet hands, or are frustrated with passcode entry)
- Accurate blood pressure readings would change how you manage your health
- You already have a functional Ultra 2 or Ultra 3
- You're willing to pay full retail ($799+) and wait until September
How Does Ultra 3 Compare to Competitors Right Now?
At $609, the Ultra 3 faces stiff competition:
- Samsung Galaxy Watch Ultra ($639) — Similar price, works with Android, larger display. The best Ultra alternative for Samsung/Android users.
- Garmin Venu 4 ($549) — Better fitness tracking depth and longer battery life. The Fenix 9 is expected later in 2026 with even more features.
- Google Pixel Watch 3 ($154) — A fraction of the price with solid Fitbit integration. Not rugged, but excellent value for everyday smartwatch use.
