The overall appearance of the Apple Watch Ultra 3 has not changed much compared to the previous generation. The biggest improvement comes from the screen with LTPO3 and OLED technology, making the bezel 24% thinner while keeping the same case size.

The device already supports satellite connectivity, allowing users to text emergency services and share their location when there is no mobile signal. If the watch detects an accident or a hard fall while you are unconscious and out of range, it will automatically contact emergency services.

Apple Watch Ultra 3 adds 30-day vascular reactivity-based hypertension risk monitoring.

The new Sleep Score feature analyzes sleep quality based on duration, regularity, and sleep stages. Users can also track heart rate, blood oxygen, ECG, and more.

As for battery life, Apple boosts it to 42 hours in regular mode and up to 72 hours in Low Power Mode. With continuous outdoor GPS workouts, the watch can last 20 hours while still measuring full heart rate.

The device integrates a virtual trainer that can give voice suggestions based on heart rate, speed, distance, and training history. The Workout app has also been refreshed with more customizations, increasing synchronization from iPhone to watch.

In the Vietnamese market, Apple Watch Ultra 3 is offered by Apple with prices starting from 24 million VND.
