Design and build quality

Rugged titanium case

Apple designed both Ultra models around a 49 mm titanium case with a flat sapphire crystal. The metal’s strength and corrosion resistance make the watch suitable for saltwater, desert dust or snow. Raised side rails protect the Digital Crown and side button, while the orange Action button on the opposite side provides quick access to workouts, waypoints or dive functions. The watches support interchangeable Ocean Band, Alpine Loop and Trail Loop straps to match different activities.

Durability and water resistance

Both watches are certified to 100 m water resistance under ISO 22810 and can handle recreational scuba diving down to 40 mappleinsider.com. They also meet MIL‑STD‑810H standards for shock, vibration and extreme temperatures, making them well‑suited to mountaineering or desert treks. Apple includes a loud siren and dual speakers for emergencies and uses dual microphones with wind‑noise reduction for clear calls in harsh conditions.

Unchanged physical design

There are no external design changes between the original Ultra and Ultra 2appleinsider.com. Both share the same dimensions, weight and button layout. While this continuity ensures band compatibility, it means Apple has yet to address the watch’s large footprint. People with smaller wrists may find the 49 mm case bulky, and there is still no smaller Ultra variant. Users seeking a compact watch should consider the Apple Watch Series 9 or Series 10 instead.

Display improvements

Brightness boost

The first Ultra introduced Apple’s largest and brightest watch display at 2 000 nitsmacrumors.com. The Ultra 2 retains the 49 mm LTPO OLED screen but pushes brightness to 3 000 nits, a 50 % increase, and can dim down to 1 nit for nighttime useappleinsider.com. This extra luminosity improves readability when mountaineering in snow glare or diving in clear water. Reviewers report that the flashlight function, which uses the screen as a torch, is significantly brighter and can be boosted via the Digital Crown.

Modular Ultra face

Both models run watchOS 10 and support new widget‑based faces, but only Ultra 2 includes the Modular Ultra watch face, which uses the entire screen to display metrics like altitude, dive time or running paceappleinsider.com. The face takes advantage of the brighter display and S9 chip to update real‑time data smoothly.

Performance and hardware

S8 vs S9 processors

The original Ultra runs on the S8 System‑in‑Package (SiP), derived from the A13 Bionic chip. It delivers smooth performance for most tasks, from tracking workouts to navigating maps. However, the Ultra 2 upgrades to the S9 SiP, which contains 60 % more transistors and a 30 % faster GPUappleinsider.com. The S9 also has a 4‑core Neural Engine, enabling machine‑learning tasks such as gesture recognition and on‑device voice processing.

New capabilities with S9

The S9’s additional processing power enables:

• On‑device Siri – The watch can process many voice commands locally without contacting Apple’s servers, providing faster responses and improved privacyappleinsider.com. You can start workouts, set timers or check health metrics even when offline.

• Double Tap gesture – By detecting a subtle double tap between your thumb and index finger, the Ultra 2 can answer calls, scroll through widgets or control musicappleinsider.com. It uses accelerometer, gyroscope and optical heart‑rate data with the Neural Engine to identify the motion. Reviewers report that the gesture works most of the time but occasionally misfires.

• Precision Finding – The second‑generation Ultra Wideband chip allows the watch to locate a nearby iPhone 15. On screen, you see an arrow and distance indicator, and haptic feedback guides you to your phoneappleinsider.com. This is particularly handy at campsites or crowded gyms.

Storage

Apple doubled storage from 32 GB on the original Ultra to 64 GB on the Ultra 2. The extra space is helpful for offline maps, dive logs, training programs and music. While streaming services reduce the need for local storage, adventurers in remote regions may appreciate the option.

Health, fitness and adventure

Shared sensor suite

Both models offer an extensive set of sensors: dual‑frequency GPS (L1+L5) for accurate location, electrical heart sensor for ECG, third‑generation optical heart‑rate sensor, blood oxygen sensor, skin temperature sensor for cycle tracking, accelerometer, gyroscope, barometer, depth gauge and water temperature sensorappleinsider.com. They support Crash Detection, Fall Detection, Emergency SOS, and International Emergency Calling. The Oceanic+ app turns the watch into a recreational dive computer, offering dive planning and real‑time decompression data.

Workouts and outdoor tools

The Action button can start workouts instantly or mark laps mid‑session. Both watches support Multisport mode, automatically transitioning between swimming, cycling and runningappleinsider.com. The watches can display running power, cadence, stride length and vertical oscillation for advanced training. Hikers and climbers benefit from a built‑in compass with Backtrack, which retraces your path if you stray off course. Freedivers and surfers can track depth, water temperature and tides; the Ultra 2’s brightness makes underwater metrics easier to read. New watchOS 10 features like mood journaling and vision health reminders appear on both models.

Health monitoring

Users can record ECGs, measure blood oxygen, receive high and low heart‑rate alerts, log menstrual cycles and monitor sleep. The temperature sensor tracks nightly body temperature trends for cycle predictions. The Ultra 2’s on‑device Siri can access and log health data without internetappleinsider.com, though the underlying sensors remain identical across both models. Crash Detection and Fall Detection send alerts to emergency contacts and automatically call services when needed.

Battery life and charging

Apple rates both models for 36 hours of typical use and up to 72 hours in Low Power Modeappleinsider.com. Typical use includes time checks, notifications, app use and a one‑hour workout. Though the Ultra 2’s battery is slightly larger (564 mAh vs 542 mAh)macrumors.com, the brighter display consumes more power, resulting in comparable endurance. In practice, reviewers report around two days of battery life under normal conditions and longer if you engage Low Power Mode.

Both watches charge via a magnetic USB‑C fast‑charging cable. Apple states they can charge from 0 % to 80 % in roughly 45 minutes and to 100 % in about an hour. Quick top‑ups during showers or breakfast typically keep the watch powered for daily use. Unlike some Garmin devices with solar panels, Apple’s Ultras rely on plug‑in charging, but the combination of efficient hardware and large battery makes charging infrequent.

Smart features and software

Double Tap gesture

Unique to the Ultra 2, Double Tap lets you control the watch with one hand by tapping your thumb and forefinger together. The gesture is context‑sensitive: it can answer calls, dismiss notifications, scroll through the Smart Stack or pause timers. It’s particularly useful during workouts, climbing or cooking. However, some reviewers note that the feature occasionally fails to register, so it shouldn’t replace button controls entirely.

On‑device Siri and dictation

The Ultra 2’s S9 chip processes many Siri commands locally, reducing latency and protecting privacy. You can start workouts, set waypoints or ask about your heart rate without an internet connection. The S9 also improves dictation accuracy by 25 %, making voice messages and note taking more reliableappleinsider.com. The original Ultra must send voice requests to Apple’s servers, which introduces delays and requires connectivity.

Precision Finding and HomePod integration

The second‑generation UWB chip in the Ultra 2 enables Precision Finding of iPhone 15 devicesappleinsider.com. When your phone is lost nearby, the watch displays an arrow and distance indicator and vibrates as you get closer. The watch also integrates with HomePod speakers: as you approach a HomePod, a Now Playing interface automatically pops up on your wrist, and you can hand off media back and forthmacrumors.com. The original Ultra lacks these capabilities.

Shared smart platform

Both Ultras run watchOS 10 and support the Smart Stack widget system, redesigned apps, cycling power metrics, and features like Medication reminders, Family Setup, Emergency SOS and Apple Pay. Both also support third‑party apps via the App Store and can connect to Bluetooth accessories like heart‑rate straps, power meters and dive computers.

Real‑world impressions

Reviewers generally consider the Ultra 2 a refined version of the first Ultra. AppleInsider points out that the physical dimensions are identical and the main changes are the brighter display and S9 chipappleinsider.com. LB Tech Reviews applauds the brighter screen and faster processor but criticises the inconsistent double tap gesture. MacRumors describes the upgrades as minor and recommends that most users keep their original Ultra or buy it at a discountmacrumors.com. In short, the Ultra 2 provides useful enhancements but does not drastically change the Ultra experience.
