What does the Apple Watch Ultra 3 look like and how does it differ from the Ultra 2?
Does the Apple Watch Ultra 3 have a new design?
On the outside, Apple Watch Ultra 3 looks almost identical to Ultra 2, but the devil is in the details. Apple has retained the distinctive aircraft-grade titanium case (Grade 5) in a size of 49 mm, however, the new model has thinner screen bezels by 24%. This allows the Ultra 3 to offer a larger working area (1.99 ″ vs 1.92 ″) without increasing the overall dimensions.
Interestingly, the case of the Ultra 3 is also thinner (12 mm instead of 14.4 mm), which makes the watch sit better on the wrist.
The weight remains almost identical – about 61–62 g without the strap, so there is no noticeable difference in weight during daily use.
What materials are used in the Apple Watch Ultra 3?
Both watches – Ultra 2 and Ultra 3 – utilize the same, exceptionally durable titanium and sapphire glass that is scratch-resistant.
The construction meets the standards of IP6X, WR100 (up to 100 m immersion) and MIL-STD-810H, which is the military standard for resistance to shocks, dust, moisture, and extreme temperatures.
In practice, this means that both Ultra 2 and Ultra 3 are ready for mountain trekking, swimming, and even diving up to 40 m – ideal for outdoor athletes.
What colors are available for the Apple Watch Ultra 3?
Apple continues with two color variants:
- Natural titanium (silver)
- Black titanium
These are minimalist, elegant shades that pair well with any strap – from silicone sports to leather and fabric.

Display, performance, and battery – what has been improved in the Apple Watch Ultra 3?
Is the display in Ultra 3 better?
Yes. The Ultra 3 has a newer LTPO OLED 3rd generation panel, which provides better viewing angles, deeper blacks, and greater energy efficiency.
Although the brightness remains the same (3000 nits), in practice, the Ultra 3 is more readable in sunlight and has a smoother always-on mode with a 1 Hz refresh rate – for the first time on the Apple Watch, you can constantly see the second hand.
The resolution has increased from 410×502 px to 422×514 px, which is not revolutionary but improves the sharpness of dials and the readability of maps in workout mode.
Does the new S10 processor make a difference?
The Apple Watch Ultra 3 is powered by a S10 SiP chip, which replaced the S9 from Ultra 2.
The differences in speed are minimal, but S10 is more energy-efficient, which combined with the new display gives a real +6 hours of battery.
The new chip also enables the “wrist flick” gesture (waving the wrist for control) and better processing of AI features with watchOS 26.
How long does the Apple Watch Ultra 3 last on battery?
Apple declares:
- Ultra 2: up to 36 hours of normal usage
- Ultra 3: up to 42 hours (normally) or 72 hours in power-saving mode
Tests confirm that the Ultra 3 actually lasts up to 2–3 days with typical usage (with Always-On Display).
Fast USB-C charging in 15 minutes adds about 12 hours of usage.

Connectivity and new features
5G, satellite, and greater independence
The Apple Watch Ultra 3 is the first Apple smartwatch with support for 5G RedCap networks and satellite SOS connectivity.
This allows the watch to connect to the network even in areas without GSM coverage.
The Emergency SOS via Satellite feature allows you to send an emergency message and GPS coordinates to rescue services or emergency contacts — it works similarly to the iPhone 14 and 15.
This solution is primarily aimed at people who engage in trekking, sailing, or off-roading, where lack of coverage is a real problem.
The new 5G RedCap modem improves coverage and energy efficiency, not offering the full 5G speed known from smartphones, but sufficient for maps, notifications, or Siri.
In Poland, the 5G Standalone feature is already being implemented by operators, so Ultra 3 will be fully compatible in the coming months.
Additional connectivity enhancements
- improved antenna layout (better coverage in difficult terrain),
- UWB 2nd gen. – precise device locating in the “Find” app,
- dual GPS L1+L5 – accurate route tracking even in mountains and cities,
- Bluetooth 5.3 and Wi-Fi 4 (2.4 / 5 GHz) with lower power consumption.
These enhancements make Ultra 3 the most “independent” Apple smartwatch to date – it operates independently from the iPhone, even in the field.
Health and sports features
Both generations of Apple Watch Ultra offer a wide range of health sensors, however, Ultra 3 expands their capabilities through software.
The watch monitors heart rate (optical 3rd gen), ECG, blood oxygen (SpO₂), body temperature, and detects falls and accidents (Crash Detection).
The new features in Ultra 3 are:
- notifications for hypertension,
- Sleep Score – daily sleep quality assessment,
- Workout Buddy – an intelligent AI coach from Apple Intelligence, analyzing progress and motivating during workouts.
In terms of sports, both models offer:
- measurement of running power, stride length, and ground contact,
- precise GPS L1+L5 and barometric altimeter,
- Multi-sport mode (triathlon, cycling, swimming, climbing),
- 86 dB emergency siren and Backtrack mode (return navigation).
The watches are waterproof up to 100 m, resistant to saltwater and dust, and thanks to the EN13319 certification, they can serve as a dive computer.
Software and Support
How long will Apple update these watches?
Apple is known for its long support of its devices, and the Ultra series is no exception.
Apple Watch Ultra 2 debuted with watchOS 10, and after updates, it now runs on watchOS 26, while Ultra 3 comes factory-installed with this version.
How long will support last?
- Ultra 2 – security and system updates expected until around 2028,
- Ultra 3 – full support until 2030.
This means that by purchasing the Ultra 3, you gain two more years of updates, which translates to a longer device lifespan and access to new Apple Intelligence (AI) features that may require the newer S10 chip in the future.
Compatibility and Ecosystem
Both models work with iPhone 11 or newer (running iOS 26).
Thanks to integration with the Apple ecosystem, users can take advantage of:
- Apple Fitness+ (workouts with trainers),
- Apple Pay (contactless payments),
- Apple Music and Podcasts,
- health data synchronization in iCloud.
Ultra 3 and Ultra 2 also have full accessory compatibility – 49 mm bands and chargers are interchangeable between generations.
Is it worth buying the Apple Watch Ultra 3 instead of Ultra 2?
For most users, the differences between Ultra 2 and Ultra 3 are not revolutionary, but they are real.
The new model is more efficient, lasts longer on battery, supports 5G and satellite communication, and has longer support.
When is it better to choose Ultra 3?
- if you don’t have an Ultra series watch yet,
- if you often stay out of network coverage (mountains, sailing, travel),
- if you want the most future-proof model with 5G and SOS via Satellite,
- if you care about an AI trainer and longer battery life.
When is it better to buy the Ultra 2?
- when you have a limited budget – the price difference is often 400–600 PLN,
- if you mainly use the watch in the city and do not need satellite connectivity,
- if you already have the Ultra 2 – switching does not make much economic sense.
In terms of cost-effectiveness, a simple rule can be applied:
🔹 New users → choose Ultra 3
🔹 Ultra 2 owners → stick with your current model
