The Apple Watch Ultra 4 arrives four years after the original model. Across three subsequent generations, Apple added a brighter and larger display, satellite connectivity, new health sensors, more capable chips, and longer battery life. For owners of the original Ultra, are those cumulative improvements enough to justify upgrading now, or can their existing watch last another year?



Both watches retain a 49mm titanium case, an Action button, a siren, dual-frequency GPS, and support for recreational diving to 40 meters. The Apple Watch Ultra 4 starts at $799 in the U.S. Apple discontinued the original Ultra in 2023, and it no longer supports the latest major watchOS release. Here are the key differences between the two models:

Existing first-generation Apple Watch Ultra owners can reasonably keep their watch for another year if its battery still covers their usual days and workouts. Losing support for ‌watchOS 27‌ is significant, but it does not prevent the original Ultra from continuing to handle notifications, activity tracking, navigation, and its other existing features. Owners satisfied with those capabilities may prefer to eke out another year of use and wait to see whether next year's model offers a more substantial upgrade.

However, the Ultra 4 is a worthwhile upgrade for anyone already running into the original model's limitations. The new Health Sensing System provides more detailed heart-rate and recovery insights, while sleep apnea and hypertension notifications expand its health capabilities. These changes are most compelling if you will use the additional information to follow changes in your daily condition or adjust your training.

Longer battery life and satellite connectivity strengthen the case for owners who record extended workouts or regularly travel beyond cellular coverage. If your original Apple Watch Ultra now struggles to finish an outing without charging, the improved battery life is a practical reason to replace it. The larger, brighter display, newer gestures, Audio Intelligence, and expanded Precision Finding support also make the cumulative upgrade more noticeable in everyday use.

Software support is a major reason to move on. The original Apple Watch Ultra cannot run watchOS 27, so it misses ‌Siri‌ AI and the latest operating system's other additions. If those features would materially improve how you use your watch, waiting another year means accepting those limitations in the meantime.

For this week's giveaway, we've teamed up with Lululook to offer MacRumors readers a chance to win a new Apple Watch Ultra 4. Lululook makes all kinds of accessories for Apple devices, including the Apple Watch. The company has a selection of Apple Watch bands that work well with the new Series 12 and the Ultra 4 models.


Lululook's $129.99 Strata Milanese Band matches the ‌Apple Watch Ultra 4‌. It is made from 99 percent woven grade 5 titanium, and it has a coating that protects it from scratches. The Strata band comes in black and natural finishes, and the titanium is about 40 percent lighter than stainless steel.


The band has a spring-loaded titanium locking mechanism with a side-press button to open it. Lululook says the band will stay in place during workouts and activities from running to swimming. While made for the Ultra, the band works with the larger 44mm to 49mm Apple Watch models, and it comes in medium and large size options to fit wrists from 155mm to 210mm.


For a more casual look, Lululook sells the $36.99 MagDuo Reversible Apple Watch Band. As the name suggests, the band has a dual color scheme, and users can flip between two color options. The exterior of the band features pebble-textured silicone, while the interior is made of soft silicone so it is comfortable to wear all day.


The MagDuo band has a breathable hollow design to keep the wrist cool, and it uses a double-sided magnetic closure. Lululook says the magnet was tested to 1.3kg of pull, and there are extra loops for security.


Colors include Graphite Gray/Driftwood, Cobalt Blue/Mist Blue, Pink/Purple, Black/Orange, Desert Dune/Cream, and Onyx Black/Beige. The MagDuo is compatible with all Apple Watch models, and there are two size options: one for the Apple Watch Ultra and larger-sized Apple Watch models, and one for the smaller Apple Watch models.

The Apple Watch Ultra 4 arrives three years after the Ultra 2. Across those two generations, Apple added satellite connectivity, a larger display, new health sensors, and longer battery life. Are those changes enough to justify replacing an Ultra 2 or paying more for the newest model?


Both watches retain a 49mm titanium case, an Action button, a siren, a 3,000-nit display, dual-frequency GPS, and support for recreational diving to 40 meters. The Apple Watch Ultra 4 starts at $799 in the U.S. Apple has discontinued the Ultra 2, although its refurbished store currently lists it from $589. Here are the key differences between the two models:

Is It Worth Upgrading From Ultra 2 to Ultra 4?

Most Apple Watch Ultra 2 owners should keep their watch if its battery still covers their usual days and workouts. It supports watchOS 27 and ‌Siri‌ AI, and continues to get new features through software updates.

The new Health Sensing System is the strongest reason to upgrade an Ultra 4. It measures heart rate every five seconds throughout the day and collects HRV data more frequently, enabling Recovery HRV, daytime Vitals, and the Readiness app. If you will use those insights to adjust your training or better understand changes in your daily condition, the ‌Apple Watch Ultra 4‌ offers a substantially improved health-tracking experience.

The S11 chip strengthens the case to upgrade. Alongside twice the memory, it enables more accurate all-day step counts, a Steps complication, and Audio Intelligence. Sound Recognition can alert you to important surrounding sounds on your wrist, while music recognition can identify songs automatically.

Satellite connectivity and longer battery life add further reasons to switch, especially if you spend time beyond cellular coverage or record long workouts. Apple's ratings increase from 36 to 50 hours of normal use and from 12 to 18 hours of standard outdoor workout tracking. The slightly larger display and faster charging are welcome improvements, but the new sensing and chip-enabled features make the bigger difference.

Should You Buy an Ultra 2 or Ultra 4?

For most people buying an Apple Watch Ultra now, future-proofing is the strongest reason to choose the latest model. Its S11 chip, 4GB of RAM, and Health Sensing System already enable Readiness, more detailed recovery metrics, and Audio Intelligence features. Live Rewind and ‌Siri‌ Recap are due later in 2026. If you plan to keep your watch for several years through successive software updates, that newer hardware makes the $799 model easier to justify.

The Apple Watch Ultra 2 remains a credible value option at a substantial discount. At Apple's current $589 refurbished price, it costs $210 less than a new Ultra 4 while retaining the same design and core features. Choose it if those existing capabilities meet your needs and you are comfortable passing up the Ultra 4's hardware-exclusive features.

Apple today announced "Audio Intelligence," a new suite of Apple Intelligence-powered features for the Apple Watch Series 12 and Apple Watch Ultra 4 that use the built-in microphone to help users catch missed moments in conversation and stay aware of important sounds.


The Apple Watch's Audio Intelligence comprises four features:

• Siri Recap: Uses ambient listening to generate high-level notes from conversations, such as takeaways from a team meeting or a parent-teacher conference, producing an Apple Intelligence-generated title, summary, and key points reviewable in the Siri app.


• Live Rewind: Lets users "go back in time for 15 seconds," transcribing and displaying what was just said in a conversation with a double press of the Digital Crown.


• Shazam: Automatically identifies music playing nearby and surfaces the song title and artist on the Music Recognition widget in the Smart Stack.


• Sound Recognition: Brings sound alerts to Apple Watch for users who are deaf or hard of hearing, listening for sirens, alarms, doorbells, a baby crying, and more, even when their iPhone isn't nearby.

Apple emphasized that ‌Siri‌ Recap is opt-in and configurable, telling users they "control if and when ‌Siri‌ Recap takes notes." Users can set it to always listen or schedule it for specific contexts, such as only at work or never at night, and can toggle it on or off at any time from Control Center. Apple reiterated that none of the Audio Intelligence features create or store audio recordings, with raw audio processed in an isolated Secure Exclave on the S11 chip and deleted immediately after use.

Audio Intelligence and ‌Siri‌ AI both require an Apple Intelligence-enabled iPhone, with Live Rewind and ‌Siri‌ Recap limited to the iPhone 16 or later (excluding the iPhone 16e).

The features arrive in beta later this year, starting in English, with additional languages to follow, and will not initially be available in the EU.

The Apple Watch Series 12 and Ultra 4 offer a range of new health and fitness features. Here's everything that's new.


Apple today revealed the following features for the two new devices:

• New "Health Sensing System": A redesigned sensor architecture with three main improvements, including increased electrode surface area for better ECG skin contact, photodiodes arranged in a ring for more efficient light capture, and larger, more power-efficient green LEDs for accurate heart rate readings during motion.


• Continuous heart rate sensing: Heart rate is now measured every five seconds throughout the day, 60 times more frequently than before, viewable via a new watch face complication.


• Higher-frequency HRV: Heart rate variability is sampled up to 24 times more often, with separate recovery and overall HRV values shown in a new section of the Heart Rate app.


• Daytime vitals view: A new toggle lets users switch between overnight and daytime vitals, potentially catching shifts in metrics before they show up in overnight readings.


• VO2 Max test: A new test has users set up their iPhone to watch them perform a series of exercises, delivering results immediately alongside data from their Apple Watch.


• Most accurate step tracking: A redesigned pedometer model with new machine learning algorithms improves distance accuracy for indoor workouts and all-day step counts.


• Steps complication: A brand-new watch face complication, enabled by the S11 chip, lets users track their step count in real time.


• Longer workout battery life: Up to 10 hours during an outdoor workout, 25% more than the previous model, with 15 minutes of charging now delivering up to 12 hours of extra battery. The Apple Watch Ultra 4 goes further, with up to 50 hours of everyday battery life, 84 hours in Low Power Mode, and a new Max Extended Workout mode rated for up to 45 hours of outdoor tracking; 15 minutes of charging adds up to 18 hours of battery.

The Apple Watch Series 12 starts at $399 and the Apple Watch Ultra 4 starts at $799, with pre-orders for both open today and availability beginning Friday, September 18.
