Design, Case, and Display of the New Smartwatch
The new model features the same 49 mm impact-resistant case as the Apple Watch Ultra 3. It is made using 3D printing from 100% recycled Grade 5 titanium. Overall, the device is made from 45% recycled materials, while the previous model contained only 40%. Apple Watch Ultra 4 is available in two case finishes: natural and black titanium. New band colors have also been added to the Alpine Loop, Trail Loop, and Ocean Band collections.
The customizable physical Action Button makes it convenient to control various functions. Use it to:
- start a workout;
- move to the next interval;
- turn on the flashlight.
With a case thickness of 12 mm, the Apple Watch Ultra 4 smartwatch weighs from 61.6 to 63.1 g, depending on the color and version.
The Digital Crown with haptic feedback is used to move between metrics such as elevation, segments, and heart rate zones. There is also a side button on the case that can be used to access emergency features.
Apple Watch Ultra 4 can be controlled with one hand without touching the screen. Single and double taps help open a widget, answer a call, stop a timer, or control music. A wrist flick can quickly dismiss a notification or silence an alert.
The new model features a wide-angle Always-On Retina display protected by durable sapphire crystal. The maximum display brightness is 3,000 nits.
The watch also introduces Audio Intelligence features that help work with speech and ambient sounds. The set includes the following capabilities:
- Live Rewind displays a text transcript of the last 15 seconds of a conversation;
- Siri Recap creates a brief summary of a conversation;
- Sound Recognition identifies important sounds in the surroundings;
- Shazam recognizes music playing nearby.
Data processing takes place directly on the watch without saving the original audio recordings. Importantly, in Armenia, Audio Intelligence, Live Rewind, and Siri Recap have no regional restrictions, but their use requires a compatible device and a supported interface language. 
Processor and Battery Life
Outdoor enthusiasts were impressed by the updated specifications of the Apple Watch Ultra 4. This model runs on the new S11 processor — Apple’s most powerful chip for watches. The processor helped improve step tracking and increase the accuracy of heart rate measurements, while also enabling Audio Intelligence features.
Battery life has also increased compared with the Apple Watch Ultra 3. The device lasts up to 50 hours in normal mode and up to 84 hours in Low Power Mode. This is 8 and 12 hours longer than its predecessor, respectively. Two modes are available for extended workouts:
- Extended Workout — up to 25 hours of battery life with GPS and heart rate tracking enabled;
- Max Extended Workout — up to 45 hours with GPS for running and walking workouts.
The new model also charges faster than the 2025 version. After 15 minutes on the charger, the watch is ready to run for another 18 hours.
Apple Watch Ultra 4 for Swimming and Diving
Use the new model for swimming, snorkeling, and high-speed water sports — it has a WR100 water-resistance rating and is suitable for diving to depths of up to 40 m. The device can:
- determine stroke count and swimming style;
- calculate the total distance;
- record the average pace;
- monitor swim sessions;
- measure water temperature.
Thanks to the depth sensor, the smartwatch automatically activates diving mode — simply submerge to a depth of one meter. In this mode, you can view the current and maximum depth, as well as track the duration of the dive. The watch saves water entry and exit points, making it easier to retrace the route after a swim or dive.
You can install a dedicated app from the App Store to track depth, dive time, and other underwater metrics. During a dive, the Digital Crown makes it convenient to view and switch between information on the display.
Health Features and Sensors
To track health metrics, the device features the Health Sensing System with new heart activity sensors. Together with the S11 processor, it accurately measures heart rate every 5 seconds thanks to the green LEDs in the optical sensor.
Heart rate variability (HRV) tracking capabilities have also been expanded — the device now collects this data up to 24 times more frequently. In the Heart Rate app, you can view the following metrics:
- Recovery HRV — shows how HRV changes each day;
- Overall HRV — provides an overall picture of HRV changes.
With Daytime Vitals, you can view health metrics separately for daytime and nighttime periods. This helps you notice changes in the data.
Apple Watch Ultra 4 also introduces a new activity feature — Readiness. It analyzes sleep, activity, and training load. The system evaluates the body’s condition on a scale from 0 to 10 and provides recommendations that are updated throughout the day:
- Recover (0–1 points) — give your body time to recover and avoid planning workouts;
- Pace Yourself (2–4 points) — choose a more moderate level of activity;
- Ready (5–7 points) — continue with your usual workouts, as your body has recovered;
- Go For It (8–10 points) — move on to intensive training.
The S11 chip and new machine learning algorithms have enabled more accurate step counting and distance measurement during running and walking workouts. A new Steps Complication feature has also been introduced, allowing you to track your step count on the screen in real time.
Apple Watch Ultra 4 retains the health features already familiar to users. The smartwatch can track sleep, notify you about changes in heart rate, and record a single-lead electrocardiogram in the ECG app.
