Apple Watch Ultra 3 is an evolution, not a revolution compared to Ultra 2 – both watches look almost identical, but Ultra 3 has a larger display, longer battery life, satellite connectivity, and a 5G RedCap modem. For most users, Ultra 2 will still be a great choice, but if you are just buying a premium smartwatch or need maximum independence in the field – Ultra 3 is the best choice for 2025.

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) with 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 – around 61–62 g without the strap, so in everyday use, there is no noticeable difference in weight.
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 glassthat is scratch-resistant.
The construction meets IP6X, WR100 (up to 100 m immersion) and MIL-STD-810H, which is a 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 refresh rate of 1 Hz – 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 training mode.
Does the new S10 processor make a difference?
The Apple Watch Ultra 3 is powered by S10 SiP chip, which replaced 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 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 h of normal use
- Ultra 3: up to 42 h (normally) or 72 h in power-saving mode
Tests confirm that Ultra 3 actually lasts even 2–3 days with typical use (with Always-On Display).
Fast USB-C charging in 15 minutes adds about 12 h of usage.

Connectivity and new features
5G, satellite, and greater independence
Apple Watch Ultra 3 is the first Apple smartwatch with support for 5G RedCap networks and satellite SOS connectivity.
Thanks to this, the watch can connect to the network even in places where there is no GSM coverage.
The Emergency SOS via Satellite feature allows you to send an emergency message and GPS coordinates to emergency services or emergency contacts — it works similarly to iPhone 14 and 15.
This solution is mainly aimed at people engaged in trekking, sailing, or off-road activities, where lack of coverage is a real problem.
The new modem 5G RedCap 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 so far – it operates independently from the iPhone, even in the field.
Health and sports features
Both generations of the Apple Watch Ultra offer a wide range of health sensors, however, the Ultra 3 expands their capabilities programmatically.
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 rating,
- Workout Buddy – an AI smart 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 seawater 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 Ultra 3, you gain two more years of updates, and consequently – a longer device lifespan and access to new Apple Intelligence (AI) features that may require a newer chip S10.
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 Apple Watch Ultra 3 instead of Ultra 2?
For most users, the differences between Ultra 2 and Ultra 3 are not revolutionary, but 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 do not yet have a watch from the Ultra series,
- if you often stay out of network coverage (mountains, sailing, travel),
- you want the most future-proof model with 5G and SOS via Satellite,
- you care about an AI trainer and longer battery life.
When is it better to buy 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 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 the current model

Nowe funkcje są wartościowe głównie dla osób, które potrzebują ich w praktyce (outdoor, bezpieczeństwo, sport).
„Ultra 3 jest dla tych, którzy jeszcze nie mają Ultra — dla posiadaczy Ultra 2 to raczej luksus, nie konieczność.” — The Verge
Users praise primarily the longer battery life, larger screen, and the sturdiness of the construction.
