As Apple's September event approaches, attention is focused on the Apple Watch Ultra 3, the model most geared toward sports and outdoor activities in the company's catalog. The most consistent leaks point to an update focused on the display, battery life, safety, and performance, with limited design changes.
In this preview, we've gathered only the data that is directly related to Apple's high-end watch and that doesn't contradict each other. The goal is to give a clear overview of what to expect from the new Ultra 3 without noise or exaggeration, and with the focus on what has the most informative weight.
Design and display
No radical design changes are expected, but small adjustments, such as those of the Ultra 2: : everything indicates that the Ultra 3 will have a slightly larger screen And, above all, brighter. Sources agree that the panel could reach up to 4.000 nits, a jump intended to improve visibility outdoors and in bright light conditions, along with greater energy efficiency for the panel.

Performance and hardware
The heart of the clock would take a step forward with the S11 chip, a processor that should translate into improved performance and lower power consumption. This advancement aims for smoother animations, faster app launches, and more precise power management, without changing the basic user experience familiar to those coming from a previous model.
Autonomy and prolonged use
Autonomy would once again be one of the model's flagships. According to the most cautious reports, the Ultra 3 would offer usage times longer than those of the standard range, with figures that, depending on usage mode and settings, could be as high as up to about 72 hours when low-power mode is activated. Beyond the exact number, the priority is to endure multi-day trips with fewer calls to the charger.
Resistance and security
In the field of toughness, the Ultra 3 would maintain its robust approach, with 100 meter water resistance (check if showering with the Apple Watch) and materials designed to withstand shocks and demanding temperatures. Regarding security, several leaks agree that Apple is working to incorporate satellite messaging for emergencies, a feature designed to send alerts and location information when there is no traditional cellular coverage.
Health and smart features
In health, small refinements are expected rather than drastic leaps. Apple is reportedly testing tracking the blood pressure, but there are no guarantees that it will arrive with this generation. New sleep metrics and a digital training coach AI-assisted (Workout Buddy). Meanwhile, the Apple Intelligence platform is not yet confirmed for the watch; there is talk of possible features such as message translation or automatic replies, although these are just expectations for now.
Price and Availability
In terms of prices, Apple tends to maintain benchmarks between generations: forecasts place the Apple Watch Ultra 3 around $799 in its base configuration. Its announcement is expected at Apple's event on Tuesday, September 9 at 19:00 PM (CET), alongside the Apple Watch Series 11.
Ultra 3 vs Series 11: Who is each one for?
The Ultra range is aimed at those who prioritize endurance, autonomy and safety features for mountain, sea or other demanding environments. Compared to Series 11 (which would presumably start around $399, with 50m water resistance and brightness up to 3.000 nits), the Ultra 3 would offer 100m water resistance, brightness up to 4.000 nits, and a more capable battery. For more urban, everyday use, the Series 11 makes more budget sense; for long hikes and outings, the Ultra 3 is a better fit.
With what has been leaked so far, the new Ultra reinforces its role as watch for demanding scenariosBrighter, more efficient, with extended range and safety features that can make a difference. Official confirmation is still pending, but the roadmap points to a coherent evolution focused on what matters most outdoors.
